    Re: .375 GSC 355 grn SP bullets PICTURES Later, Please don't. I was being open about the news I just received, and the gentleman that presented that information was reliable. Sorry for that, but it is a shout box! A simple no would suffice...and yes, still awaiting response from my...

    .375 GSC 355 grn SP bullets PICTURES

    Re: .375 GSC 355 grn SP bullets PICTURES I go back and forth sometimes on whether or not I should reply, and I would have to say it's just my nature, but I feel a little insulted. No, I'm not upset, but I do like to think I know what I say before I say it. I believe the group I work with, to...

    .375 GSC 355 grn SP bullets PICTURES

    Re: .375 GSC 355 grn SP bullets PICTURES Noel, thank you, you are right, we wouldn't be doing much without his work. As for MV's, we have tested the design to over 4,700 fps, though not with that bullet. And no, accuracy does not suffer. In fact, I have seen 1/4MOA groups with the SP's at...

    .375 GSC 355 grn SP bullets PICTURES

    Re: .375 GSC 355 grn SP bullets PICTURES Steve, the LM-105 bullet was designed and built by GS Custom Bullets. The design had been updated and improved, and is currently sold by them. GSC uses all copper, a much better material then brass or bronze, so it is the 295 grain .338 SP. The GSC...

    Barrett 82A1 Accuracy Expectations or Suggestions?

    Re: Barrett 82A1 Accuracy Expectations or Suggesti Barretts usually don't have a good trigger pull, just the nature of the beast. I believe Anzio Iron Works was/is making an excellent trigger for the 82's! I hope he is still making them, as they were about your only option, and quite nice...

    Barrett 82A1 Accuracy Expectations or Suggestions?

    Re: Barrett 82A1 Accuracy Expectations or Suggesti Second that! One thing you can do, or talk to your smith about, is to get a dry erase marker and mark the bold face, tips of the lugs and extractor, oh, and where the bold handle contacts the receiver. What happens is simple, small...

    .375 GSC 355 grn SP bullets PICTURES

    Re: .375 GSC 355 grn SP bullets PICTURES I am very interested in how that turns (pun) out. I've done some extensive study in the area, and have found that over spin stabilizing is not too good. Once you reach a certain ratio of caliber to length, it becomes very critical of twist...

    Re: Bullet design info Noel, I did mention I work under military contract, but besides that, I am very familiar with the ATF. And I am a US Navy Firearms technition and Ballisticion. They do, and I do, make commercial tungsten solids. I guess what I am getting at is that I was trying to...

    Barrett 82A1 Accuracy Expectations or Suggestions?

    Re: Barrett 82A1 Accuracy Expectations or Suggestions? Sounds like it's not the ammo, but the gun. You should have it checked out by a good gunsmith. Scope mount/rail might be a good place to start...groups like that are hard to produce with a gun like that!

    Rocky Mountain Bullets for 1000yd+ hunting

    Re: Rocky Mountain Bullets for 1000yd+ hunting Bulletsmith, I second Dave Viers, and recommend ABS (Advanced Barrel Systems)...Mike builds some spectacular rifles, and he can give you some good advice with gain twist barrels. http://home.windstream.net/mdegerness/prod03.htm

    Rocky Mountain Bullets for 1000yd+ hunting

    Re: Rocky Mountain Bullets for 1000yd+ hunting Hey guys, sorry to be redundent, again, but you should really check out the HV's at GS. I shoot the 265 and 300, and have kills out past 600 with the 265; not and issue. So ya, give them a go if you really want performance at that range...

    .375 GSC 355 grn SP bullets PICTURES

    Re: .375 GSC 355 grn SP bullets PICTURES So yes, those are the B.C.'s, and they are calculated on a G1. GS Custom always deducts about 5% off the calculated B.C. to bring the numbers into realism. Every company that makes bullets uses the same method; calculated B.C. The issue I see most...
