  1. You're gonna kick my a$s, but... I don't have a chrono... yet, anyway... I've got a base reference of a verified chrono load, and I'm running ladders up from there, and doing the velocity calculations before I go out there. Using this program for the velocity calculations, based on the verified load: http://shootersnotes.com/calculator/velocity-estimator/ Once I get the load the rifle likes, and the velocity that I like, I'm running JBM Ballistic Calculator to give me a good idea of the drop in mils, and I'll go out and verify it all through the scope. Planning on this being a 400-yard hunting round. http://www.jbmballistics.com/ballistics/calculators/calculators.shtml My starting load is the 90 SGK over 21.5gr RL-7 @ 2640fps. My ending load, pressures permitting, is 90 SGK over 23.2gr RL-7 @ 2826fps. 23.3gr RL-7 @ 2837fps. I'll load in 0.2 or 0.3 gr increments and build 10 loads of five rounds, tonight. Initial JBM calculations give me 3.4 mils 3.3 mils of drop at 450 yards on the 2826fps 2837fps load, and 4.0 mils of drop at 450 yards on the 2640fps load. Whatever the rifle likes the best will get the final drop calculations, and scope verification.
  2. What did you see that would cause issues? I saw a couple thou here or there, but nothing drastic. Well, besides that gas key placement. I'll look closer at cam pin cutout dimensions, because I could see that causing a problem, one platform to the other.
  3. Working on brass right now. Just dumped a whole gallon zip-lock bag into the tumbler, all once-fired PMC Bronze brass. I've had good luck with the PMC Bronze brass in the past. Ran the first 10 of them through the expander, then resized/deprimed. I'll finish off the bag and get them all cleaned again. Gonna load up 5ea on powder differences and run ladder tests this weekend. They'll all get the Sierra GameKing 90gr HPBT and RL-7 powder, CCI 400 primers. Wanted to get that done today, and actually get out and shoot the ladders, but TactiCat got his a$s over the wall and went for a stroll. I had to find him before he got someone's dog. Spent quite the time hunting for him. Said fuk it, and put out food and water, and a first aid kit, and went back out to the reloading shed. Opened the door, and he shot out of there, dirty as hell...
  4. This might be do-able. I will steal one of Kim's 9-rounders...
  5. Well, let's get this going. Optic is a Millett DMS-1 in an American Defense mount, for now. That will change. 18" midlength barrel with a 15" handguard. Trying out a new trigger, and I really like it. It's already been given a breakin workout in the trigger jig. KE Arms DMR trigger.
  6. I'm not seeing too big of a difference, besides gas key mounting differences.
  7. If you buy it, I'll help you diagnose all the issues with it. Have at it, my brother. No matter what, we can un-fuckle the thing.
  8. My last response to his photo-bomb was magnificent. I hope all PSA owners find it.
  9. He photo-bombed it all over the site, every chance he could put it in. I think I found them all.
  10. I'm making ladders tomorrow with charge weights, and shooting the shiit out of this thing, brother.
  11. You didn't hear WRONG. Early models SUCKED A$S, before PSA unfucked themselves and discontinued them... ^^^THAT happened ALOT. And then the new owners came HERE, and started asking for help diagnosing their freshly-purchased schit-pile. Unreal... That dude completely PSA-bombed your thread, when it had NOTHING to do with PSA, didn't he?... Like a drunk college a$shole in a bar photo-bombing drunk biotches...
  12. Well, your subliminal message might not work when you mount your scope mounts backwards. And, don't bridge the rail. You might want to fix that before you shoot for groups on Sunday. I'm just sayin... Fuckin Twilight Zone in here tonight, WTF.
  13. ^^^ THAT. FUCKIN. ROCKS. Hands down.
  14. Your scope mounts are on backwards. And, you don't bridge the rail. You should fix that before you go shooting for groups on Sunday. I'm just sayin'...

  16. Gun Pusher just called... "Hey man, all your SHIIT came in. A couple days ago..." Me -"A COUPLE DAYS AGO?..." Him - "Yeah, I was out of town. People are looking at it, how much you want me to sell it for?..." Me -"I'll see you first thing in the morning, how much do I owe you?" Him -"I don't know, I didn't even add it up yet." Me - "Alright, see you in the morning, I'm loading ammo tomorrow afternoon..."
  17. Shooter was yelling Aloha Snackbar while killing people... http://www.foxnews.com/us/2017/04/18/fresno-shooting-rampage-3-people-killed-suspect-who-yelled-allahu-akbar-says-hates-white-people-in-custody.html
  18. Man, where you are, we should have drone footage of the awesome beaches!!!...
  19. From what I've been able to dig up, the 1:10 twist has been stabilizing heavier .257 projectiles in the .250-3000 Savage for years. They didn't mess with a good thing. It did a good job stabilizing that 87gr projo out to 800, and worked in the past on similar trajectories, so I'm okay with it.

    Need some clarification, Rene... Me and Sisco wanna know...
  21. I found that last night and was shocked - I didn't think you'd be able to dial up the mil drop for 800, and hit with this cartridge. Especially the 87gr factory ammo. I was already committed - my barrel and dies should be here anytime now. SS, welcome to the family, brother!
  22. That's the specs on the M110A1, Mike, compared to the original M110...
  23. The 25-45 Sharps at 800 yards... Not a typo...
  24. .308 Win. SS's barrel, I'm talking about.
  25. I tried to bait them, too, and no takers... They know...
