    Range Report ATK / Lake City .50 ammo

    Re: ATK / Lake City .50 ammo There is a fair amount of variety in M33 projo's.... all similar, all a little different. Profile a little different, weights between 647 and 690 grains.... I generally use .64 or .65. You mileage may vary....

    Barnes 800 solid BR or 750 AMAX?

    Re: Barnes 800 solid BR or 750 AMAX? Dan, I have always found that my .50's shoot better and more consistent with full length sized brass. I like to take the firing pin out of the bolt, and run the sizing die down until the bolt will fall closed on the sized case without any pressure. I...

    resizing the bmg

    Re: resizing the bmg FWIW this is a very common problem. Understand there is no SAAMI spec for the .50 BMG. Each mfg uses their own chambering reamer. The closest thing there is to a standardization is the military drawing for the cartridge.

    New US Military .300 Win Mag Match MK 248 MOD 1

    Re: New US Military .300 Win Mag Match MK 248 MOD 1 FWIW........ The field testing for this round (and comparing the 210 SMK & 220 SMK) was performed by a retired operator who is currently still working in the NSW community. The decision to go with this round came from the end user up, not...

    The Next Thing in Military Sniper Rifles

    Re: The Next Thing in Military Sniper Rifles DARPA was working on a project similar to this using a .50BMG. The goal was to have an opto-electronic targeting system analyze the trace from the first round, correct and fire the second round before the first round impacted. I helped provide...

    Barnes 800 solid BR or 750 AMAX?

    Re: Barnes 800 solid BR or 750 AMAX? The BC (G1) of the Barnes 800 gr. is around 1.05. There are similar bullets available from several other mfg's: Lehigh Bullets Ten X Bullets AAA Arms & Ammo Most 50's will shoot the AMAX pretty well, the solids hold all the records, but it...

    Have you guy see this?

    Re: Have you guy see this? IMO, the similarities are in part due to the spec's defined for the PSR project........ The ring's come with the BORS system. If they had a contract, I'm sure Barrett would tailor the ring height as requested....

    Range Report Hornady 8720 - 50bmg w/ AMAX bullets

    Re: Hornady 8720 - 50bmg w/ AMAX bullets The problem with listed MV when they don't specify the barrel length, is you don't know if they are using the 45" military M2 barrel, or a 29" barrel. Makes a big difference.

    Range Report Hornady 8720 - 50bmg w/ AMAX bullets

    Re: Hornady 8720 - 50bmg w/ AMAX bullets I fired a few of these last month, but didn't have an opportunity to chrono it. It seemed rather on the "warm" side. Listed MV on the label is 2815, but it doesn't specify the test barrel length. I was hoping Hornady was going to come out with their...

    Re: Interesting comparision - SPR vs. AMAX 50 BMG 1k+ NH, Thanks for posting the comparison. Were you using H50BMG behind the AMAX's? I am currently getting ready to work up a Mk262 clone load for my SPR. Scott

    Input needed - Barrier round for SR-25

    Re: Input needed - Barrier round for SR-25 George, 1. Is the rifle fairly new? 2. How many rounds through it at this point? 3. Do you have the newest mags? Older mags had feed problems. 4. Do all the mags have the same propensity to intermittent misfeed? 5. I have had better luck using...

    Bi-Axial "suspension" Bipod Design

    Re: Bi-Axial "suspension" Bipod Design From my standpoint, I would look for the following: 1. As light as possible. 2. As stable as possible. My interest in a bipod for ELR purposes is different than in shorter range tactical uses. ELR shooting is not going to be leading moving targets, or...

    mcmillan action 50 bmg

    Re: mcmillan action 50 bmg I do not have any test data to support it, but I believe the single shot is more accurate. I have used the single shot McBros action in 4 different benchrest guns (all RB/LP) and also in my prone/tactical rifle. There is very little speed advantage to the mag fed...
