And do NOT give them any notoriety by using their name.

👍 Good for you! The feces has hit the fan with lots of stuff going on "at home" so I haven't gone as often as I like. But as soon as I get caught up (very soon, Monday hopefully) I'll not make up for it, but I'll go at least 2x a week. Last time I went I went I spent a bunch of time on the rowing machine after doing my rehab on the treadmill, and did something I haven't done in quite some time at Cardiac rehab at the hospital, I started to work up a sweat. Not doing anything outlandish for a workout just rowing at a decent pace (19spm) and resting for 1 1/2 minutes every 3. At cardiac they didn't like us to exercise too hard. 😆 I assume they didn't want to have to get out the paddles or worse yet, do the paperwork if we croaked. They just wanted us to exercise the heart muscle and no more. But I went easy on the rowing expecting to be a hurtin' unit the next day, but nothing was sore. I'll work my way up slowly with both resistance and time monitoring my vitals as I go. Heck, I haven't rowed anything for over 1/2 a century and I was VERY surprised that I wasn't hurting. I also expected my calves that don't get normal blood flow to be hurting as I was rowing, but I guess it's slow enough so as not to be an issue. That's not the case with the treadmill and that's exactly why I do it. For me just going to the supermarket is also rehab for the calves. I walk at my military pace, it's just so hard to slow down, and when the calves start to hurt I stop and let the blood catch up. My point is that normal everyday movement is also rehab for me.

Welcome to the forum!

Welcome to the forum from central Maine! No experience with flat wire on an AR10, but I have one in a .300BLK AR15 and it works fine.

I forgot! There's more. Despite therapy and exercise I'm losing muscle mass. Another thing I've done is to sell many of my long long guns and buy bullpups and SBRs. Without the barrel mass wayyyy out there they handle so much better.

Well, age and medical conditions caught up to me. I never thought I'd get to be this old. I doubted I'd live to be 20 and back then I was superman. But I have, and this is now, it's real, and all of a sudden I have this old worn out body with heart disease and peripheral artery disease (drastic lack of circulation in the extremities). My hunting and days of walking very far are behind me due to those medical conditions I briefly mentioned above. Before I started with therapy I couldn't walk very far at all w/o pain showing up not long into the walk. The alternative is having my femoral arteries sliced open, scraped out, then 2 months of bedrest. I would be able to get out of bed for no more than 15 minutes at a whack and only for taking a dump. But the therapy is working and I'm doing better to the point where I surprise myself at times with what I can do. Therapy doesn't have a rowing machine so I quit last week to take out a membership at Planet Fitness where I'll continue my therapy and use other cardiac machines to include a rowing machine. My last day of therapy at the hospital was Jan 31st and when I said goodbye to the nurse on duty to tell her my plans she suggested to me that I was moving into Phase 4 therapy from their Phase 3. Not only do I get the use of more exercise equipment but I can go as often as I want. Previously I was limited to 2x a week on the hospitals schedule. If weather dictated that it was closed on one of those 2 days, tough luck. Now I can work around the weather and still get in my therapy and exercise. Sure, I'm doing it for health but I also like to stay sharp for Steel Challenge and USPSA Action pistol, and they help me stay sharp for self and HD. Shortly after therapy began I decided to lose weight. I did a bunch of research into heart disease, fats/carbs, and such and decided to put myself into ketosis. Some may not know what that is. It's a drastic reduction in carbs consumed and that forces the body to begin to burn fat. The liver turns fat that is either consumed or stored into ketone which the cells can burn. If you've been following along you caught the "consumed fat" part and may be thinking, "But he has heart disease!". Yup. The common knowledge about heart disease is probably wrong. Fat, good fat, does NOT cause heart disease, carbs do. At least that's what my research turned up and what I acted on. Going into ketosis and flipping the bird to common knowledge was the hardest thing I ever did (Am I going to kill myself??). After all I'm betting my life. But my PCP Dr has told me that he agrees with what I'm doing. One positive spin off from radically restricting carb intake is... I was pre diabetic. Now I'm so not pre diabetic that my Dr has removed it from my medical record as a concern. I've lost 50# and and happy with my weight today. I could lose another 20# and still be happy, but those around me have told me that if I lose any more I'll look emaciated. Yet that would still be over my warrior weight 50+ years ago. For those inclined to choose keto... My GI (not the VA ) Dr told me that it's so difficult that she couldn't do it. I agree, when I first started into it it was very difficult. But now after having learned a great deal it's not terribly difficult to eat and stay in ketosis without a boring diet. But at first it was "What the hell can I eat!!???". I've been in ketosis for 3 1/2+ years and I still crave pasta, bread, pizza, fruit, pie, cake, yada, yada. Carbs are a difficult addiction to break.

Welcome to the forum!

Welcome to the forum from central Maine! In general terms where in Maine is your AO? I'm near Skowhegan.

I have function tested it and it works fine. But accuracy testing will need to wait until warmer weather.

I know, I know, they are heavy and fill only one function that I know of and while I will never own one that function is home defense for someone who can't or won't purchase a better handgun. If it's stolen or taken by the cops little is lost. Go out and buy another. Heck, that's the function of all Hi-Points IMO. They're ugly clubs that no one will ever take to the next BBQ to show it off. I've often thought that if one ran out of ammo they'd be just as deadly thrown at the invading perp due to the very massive slides that are required. I won't spend my very limited $ for one but if I was handed it I'd fire it just for giggles even though I need optics to hit anything at any reasonable distance today. But at bad breath distance sights wouldn't even be needed. A competition gun it definitely is not! Does it even have rifling?

Welcome to the forum!

I think there has been an ongoing contest to outdo each other to gather as many points as possible toward winning the most useless senator. But yeah, feinstein is right up there.

Correction (edit): the twist on my barrel is 1:7 I previously stated that it was 1:8

The sabots really require flat bottom bullets from what I recall of the way they're molded. High BC bullets would have a boattail and would have huge runout. Maybe it could be done, but I wouldn't know how to do it in a reasonable manner. In the past I found velocity to be almost magical so my thrust is toward that. But I need to find out if they will do the basics of feeding and function reliably. If that doesn't happen it's a failure. One small step at a time. This isn't going to happen rapidly. It'll be at least 1 1/2 months before I even start to think of getting my range melted and usable. . One thing at a time. I don't want to get ahead of myself. First they need the basics, to feed and function reliably. If they don't do that it's not going anywhere.

It's not a new to me idea. The military has been using it in tanks for quite some time. I think they call them discarding sabots. The Thunderbolt ground support aircraft may also use them. I used it, as do many others, with shooting black powder. The twist rate of the 300BLK was lost on me with all the other factors I was considering, but yes, it might mean a cleaner separation. I'm pretty sure my barrel has a 1:8 twist. In the end it'll either work or it won't. If I had a ballistics lab I'd be able to spend the $ and figure out what works best, but what I have is what I have and it'll either work or it won't. There's very little I can do to help it to work. I nearly forgot. That's the story I get from everyone re: the Rem' accelerators. So I guess my 3" groups weren't all that bad. It just wasn't what I was looking for. After that experiment I bought a .17 Remington and throttled the velocity down to 4060fps from 4200+. The bullets were coming apart in the air.

I'll do as I stated and post my results + or -, my interest is in helping the forum.

Absolutely legal as far as I know. Tomorrow? Who can tell, fjb and the BARF. The Sabots were still being advertised for sale in the last Firearms News.

I'm not a reloader, I'm a handloader. There's a huge difference. I wasn't fishing for attaboys, but just making "conversation". I expect nothing major as a result due to the limited powder space (I HATE repeating myself!) but stay tuned. I'll post even if it fails. It won't surprise me if it does fail.

I already stated it was out of a 10" barrel. When does it separate? I also already indicated that I didn't know and that was part of the experiment. It could be in the can which wouldn't be desirable as it would screw accuracy up but not be a disaster for the can due to the way it's made. Best if it separates outside the can. How will I know? Work up a load or loads and test. First w/o the can then with.

(You posted again)You'd be wrong in that understanding. It remains a .30, no change to the case. I'm not going to explain a sabot. Look it up (I see that you did). They're in common use esp' in tanks for the same reason I want to play with them. What I have are nylon sabots that hold a .223 bullet, what you pictured is at least similar if not exact. I just never played with them in a semi auto, or the 300BLK. Not a put down, but if you don't know reloading that might be the issue you're having. I can't promise results worth repeating, but I intend to pursue this. First they need to feed. Then the action needs to function. After that I need to get something worthy that the 300BLK can't do all by itself. But I think it's worth the experimenting.

That's a classic! Too funny! Who watches that crap? Stupid question on my part... Duhhhhh! The folks at Davos.

Good to know. I'll start looking for a replacement.

No not really. The difference is the size of the piston that the pressure pushes on and the lightweight bullet as payload. It's totally different than 5.56. Load data gets thrown out the window*. I might need to use scary fast powder and as I get older I get less adventurous. FWIW, I never blew up anything because I always made small moves and I will this time too. Maybe .220Swift or .22/250 would be more like what I was getting from the .308 handgun, but That would require another rifle. I'm also not going to look and see what the load data is for those cartridges. Maybe they use similar powder charges, but I doubt it. They don't need it because they don't use an oversize piston. It's probably not going to give me what I want though due to the low volume of the 300BLK case. It's certainly not going to be as dramatic as what I got with .308 Win. I would expect it to give me higher velocity than I would get from the same short barrel if it was chambered for 5.56. But there's only one way to find out. As for as the can... Not all cans are built the same. Should the sabot get caught in my can it's just a matter of unscrewing the can from the barrel (or just use long rod through the upper) and push it out. Think of the innards as a sort of smoothbore barrel extension. It's less about quiet and more about being short and containing the blast which it does very well (Amtac CQB). *I'm not going to check my actual load data, so no one should think that what follows is something to be copied. With .308 I remember a full charge (40+ grains) of 1680. The load data that came with the sabots used powder that would have been used with, for example, a 150 grain .30 bullet. I tried their load but knew before busting a primer that it was all wrong; safe, but wrong. If I hadn't run out of room for powder in the case I could have gotten even higher velocity. Or I could have gone to an even faster powder, but my next fastest powder was IMO too big a jump so I stopped where I was. Maybe today I could make that jump, but that experiment was shelved. I didn't expect better accuracy if I got higher velocity. But I want to see what a 10" barrel in 300BLK will give me. That's the reason for doing it. Not to duplicate what a 5.56 will do. Right now my fast load is a Maker 85 @2300 fps. I know I can do better than that with a bigger piston, lighter bullet, and MUCH faster powder. If it feeds, and that's a big if, will it even cycle the action? Will there be enough gas at the pistol length gas port for function? I suspect yes, but I don't know that due to the greatly reduced powder volume.
