In this edition of the BULLETin we have some exciting new developments at JP to tell you about. For starters, we’re pleased to see that the numbers are really on our side when it comes to competitive shooters choosing JP. As Front Sight pointed out in their July/August issue, JP outmuscled all the “industry superpowers” to prevail as the most popular rifle brand at this year’s Multigun Nationals. While this was the “biggest surprise” of the equipment survey according to Front Sight, it just confirms the trend we’ve seen developing for years of shooters choosing us when they need to perform at the top of their game. In more local news, we're glad to announce that JP is expanding once again! If you’re reading this, I’m sure you haven’t failed to notice how the demand for ARs and components has absolutely skyrocketed in 2012, and we have certainly not been immune. It was only two years ago that we purchased and renovated a new and larger industrial space and thought we'd never fill it up. Now, we're bursting at the seams and will again be doubling the size of our operation by moving into our current building's twin next door. Pretty soon we'll have a whole JP campus on our hands! As some of you might have seen, we've also launched a great new online tool in our JP Rifle Builder, which finally allows you to spec out complete rifles, uppers and lowers to your heart's content, save them for further reference and submit them directly to us when you're ready to order. This was a big endeavor, and we're expecting to see it really take off as the new high-tech way to get our rifles and complete assemblies into the hands of customer. For new media, make sure to check out the first installment of our new YouTube videos videos with John Paul giving a rundown on the various bipod systems he uses. Plus, we have a JP Tech Tip article from professional hand gun trainer and gun writer Dave Spaulding talking about his experiences with the JPoint and the advantages of MRD sights for pistol use. Finally, check out the links below for the new products coming online, such as our new RCS™ (Rapid Configuration System) hand guards that now allow for convenient rail mounting directly to the tube without the need for backer plates. There's also the JPA-CPG heavy-duty winged rail mount for both the JPoint and Docter sights and the JPHG-SM single-point QD swivel point for all JP hand guards. Last but not least, 2012 marks the tenth birthday of our first machined-from-billet rifle, the CTR-02. In its honor, we've produced an extremely limited run of flashy, commemorative anniversary rifles that are impossible to miss. New Bipod Video "Red Dot Rampage" by Dave Spaulding Versatile and tactical-ready, our new RCS™ Hand Guards are now available.

Hi seasprite, I was re-reading these last recent posts here on your thread. I was wondering about neck tension. I know of it but don't know how you get that measurement or how you size for it if there is something else besides the regular sizing in a FL sizing die. Is there another gauge for this? What do I need to know? Edit: P.S., I looked over the BC calcs you did and thought it would be fun to compare your data of your happy load you settled on right now. 1) because I'm bored waiting for my brass to finish cleaning in the vibrator, & 2) because I can't stop playing with the chrono and it's fun. So I ran it through my chrono trajectory calculator, and I entered for point blank zero too. Do you want to see it?

seasprite OMG I dunno if it would have occurred to me to fire them in that order, 2.815 on down to 2.790. Wow I hope I woulda, LoL!!! You know what I was looking at my brass last night. After I shoot a group I replace brass in the box the way I they were sorted for load before I fire them, so I know what they were for inspection later. The ones used in the upper charge weights look great, better than the lowest charge weights. Maybe I'll just do the 48.1 grain node afterall, or just 48? Thank You seasprite, have a good 4th, have a good 4th everyone.

You idiots must have scared her off to AR15.com <lmao> <lmao> <laughs> :o

Here's a cool thing that that chrono does. It is a balistic calculator. All you need to know is the distance of your sight to the muzzle bore, the velocity of your load & the BC of the bullet. It has over 800 bullet types stored in there. I entered the info from a group I shot yesterday using IMR 4064, 168 Amax and a average velocity of 2498. Then it asks what kind of ranging, like Point Blank or Zero Range, I said zero range. It asks what distance like starting at 100 & ending I said 500. It calculates bullet drop and velocity at a given range. here is what it does for you :)

Survivalshop, yes it's a Forster, both of those are. But I love that seater die it makes it sooooo much easier to find your depth. Yeah I'm thinking of trying SMK 175's and 178 Amax's I. Future. Someone in my ear is telling me to try 155 scenars too. My barrel 10 twist JP match cryogenic I think it's a button rifling too. Someone said JP uses Wilson blanks <dontknow> Okay you guys talked me into it. I'll do some comps with different seating depths, after all I do have the Forster now. Okay I'll try 2.790 up too 2.815. I will use the low node. I think I saw a good one at 48.1 gn too but I don't want to mess with that pressure right now, if at all. Well maybe, heck those were good velocities for a 16".

Mike, they are all seated to 2.800". Now won't be a good time for comparing bolt crud because I shot some other powder through it after the CFE.. I try to remember though.

Okay, yes that's good then. I bet you will a difference when you do that step.

seasprite, I'd be curious to see what happens for you if you tried Remington #9 1/2 primers. My SD's are lower than yours but why? <dontknow> I have 1500 remaining of those. I was told they have thick jacket walls and less prone to slam fire in a auto loader. It's why I use them anyway, but I'd like to try something different to have a look see.

yes 2.800 and all verified with caliper. I would try 2.815 like you said you like

Thanks bro!!! :)

Thanks seasprite, I was hoping you would find this soon <thumbsup> I don't think I've settled on anything yet, I have not digested it all and not really sure if I saw any groups tightening up anywhere, but maybe that 48.1 gn CFE looks a little better somehow as far as the grouping? I have to take another look here. From 47.1 gn to 48.3 gn there is not really a dramatic increase in velocities, maybe about 40 FPS or so. I'm not going to go any higher because I don't feel comfortable with any more pressure at all. I think a good idea would be in the other direction below 47.1 gn and see what happens. When I fired the first shot with 47.1 gn CFE and looked at the chrono read out it blew me, and my bro in-law, away. We weren't expecting that much velocity from the get go out of my 16". And when he shot the 47.7 charge weight out of his 24" SR25 and averaged 2898 FPS and a SD of 17.1, he showed pressure signs with the primers bulging a bit. I will be more comfy going the other way with this powder. I don't know if I'll do anything with seating depth. Like you say going a little deeper could be provoking pressure. And I can't go any further than 2820" COAL with my Pmags, as you know. But I will make them all consistently 2800" or consistent wherever I put them. I think the main thing is powder and bullet and how well/consistent you prepare them. I want to try other bullets & weights. I think 175 SMK & 178 AMAX, and 155 scenar. Try some RL15 or something else. I dunno lots to think about........

Here's a new goodie we just got too

This is about the average I am able to shoot as far as how those holes in the paper end up. I really feel that the gun is better than that. The scope is just a 6x and it's FFP. At 6x this particular reticule is a bit too thick for precision. I have another 6x FFP coming and the reticule specs and the reticule design should make for some improvement but not like a scope better suited for this stuff, of course I did want that type of scope for a different purpose. I wouldn't be surprised if i get a low end 10x or something if I wanna really shine more just at the range. But a lot of it, probably most of it is me. I darned well know when I yank one and I think I do it a lot. More trigger time so I can learn how to drive this thing. But as for the trigger it is awesome.

After my first 4 groups the next one blew up bad, you will see in the first pic here. So I cleaned my barrel and it got better. after that the rest are the 4064 charges.

Now the target pics: All the dots are 2"

That was it for the CFE. but I did bring some loads I did with IMR 4064, 168 gn AMAX @ 2.800 COAL all verified with caliper, Winchester brass all weight sorted & Remington # 9 1/2 primers. By the way those are all the same components i used with the CFE233 rounds i did, don't think I mentioned that above. Look closely at this first one with the IMR 4064 43.5 gn. Now I like that ES!!! Beats me why the others were no where near that one <dontknow> IMR 4064 printouts:

I had a group loaded with 47.7 gn Hodgdon CFE223 but I don't have the printout. My brother in-law asked me if he can shoot one of my groups out of his SR25. He has one of the original from Knight's from when they were using barrels from Remington. His is a Remington 24" bull. He has the printout, I wish i would have thought to print another so i could show you what that group did. I do have a pic of the target I will post in a minute. But I kid you not, his group averaged over 2900 FPS, 168 gn AMAX!!! We think it was a little too hot in his gun and I saw some mushrooming in some primers, I think that's what it was. Never saw that in mine even with the hottest ones I had, which were hotter. But his group was better than any of mine, which kinda suck.... More printouts:

OK I'm chilled now had a nice nap. It's late but i have energy. To start off the first two groups I liked the velocities coming out of the 16" JP match barrel. But I have to say the Winchester brass heads were lot's of times coming out messed up. One was kinda chewed, and several had extractor marks. This had me worried and it crossed my mind to seriously stop right there. but i decided to try one more group and that one improved a whole lot. Out of all the groups charged with the CFE223 there were no bad pressure signs having to do with the primer, albeit sometimes a little cratering around the firing pin whole, sometimes I would see the slight presence of ejector mark, but nothing else. I pressed on and shot it all. One thing I don't like is most of the ES's. You will see what I mean. I used our new PACT Professional XP Chronograph my Bro in-law and I went in on together. It does lots of things and I have not yet learned everything about how to operate all functions but got enough to get somewhere today. It has a printer. I am posting pics of the printouts to make it all easy to follow here, plus it's really cool <thumbsup> So here is all the data. I'm just going to let it speak for itself, should be self explanatory, I guess. EDIT: Load info Hornady AMAX 168 grain Winchester case Remington #9 1/2 LRP Powder, Hodgdon CFE223 (later data on IMR 4064) 2.800" No Crimp END EDIT

http://m.dillonprecision.com/mcontent/p/9/pid/25547/catid/3 This will do nicely <thumbsup>

I just got home. I have lots of velocity data I need to put down here but need to settle myself down and try and do at least half decent report for you all. But I am excited to say that in my 16" .308 I saw groups with what I think are great velocities. I'll try and report like seasprite did. How about 47.1 gn CFE @ like 2660 or so average? That was what I started with... I chrono'd same bullet with 43.5 gn IMR 4064 and averaged like 2500 FPS, that surprised me a lot, figured way less than that before chrono. Give me time I'll work on your report....... :)

an absolute must IMO!! And it's how I realized I needed to reset my sizing die to do that shoulder bumping. And it's how I know I trimmed it good or how I know I need to trim. I have so far thrown out some brass when I can't get something right after sizing then checking with the case gauge. You need one!!!

LoL brother unforgiven!! Hey did you place your finger over your mouth with like the V sign when you wiggled your tongue? <lmao>

Fkg BASTARD!!!! Trying to make it easy pickings for his PLA/PRC friends....
