Re: Anyone want to sell .50 BMG reloading gear?

FYI - You might want to read thru the posts in the Ammunition/Reloading section in this forum. The very last posting in that section.

A number of members have posted good info, plus you might want to post your query there. You might get more responses.

Good Luck. :det:

Is it 55.000, 60.000, 65.000 PSI or something else ?

Best regards


OK...
The current load generates 57,000 psi, and the cartridge has a maximum operating pressure of around 60,000 psi.

Re: Hello from Germany

One thing I would like to know: What is the maximum "safe" pressure for a Barrett Model 99 (.416) with 32 inch barrel using the original Barrett brass cases ? Thank you. I don't know the "safe" pressure figure, but Barrett recommends the following for reloading: APPROVED RELOAD ...

Re: Height of optic mounting plane?

Sorry if it came off as a snippy response, it was just retaliation . I was just hoping for an exact measurement from the manufacturer. I apologize. Retaliation is an act of revenge. Before you initiate retaliation on someone who you think has wronged you, consider whether he might A) Be right; or B...

Re: Neck Sizing for M82A1

I know it is generally discouraged to only neck size for semi auto rifles but I was wondering if anyone had tried it in their M82A1 or M107. It would be nice to be able to have the benefits of custom brass and maybe squeeze a little more accuracy out of my rifle. Any and all input is greatly apprec...

To belay any prolonged discussion of "Precision" vs. "Accuracy", I offer the following case examples to explain the differences. Case 1: Not accurate, NOT precise: A shooter aims and fires four shots at a target. Upon examining the target, the shooter sees that all four shots are...

Re: EFFECT'S OF REDUSED RECOIL SYSTEM ON ACCURACY

so,u dont know why or how does movement of the barrel reduces the accuracy? Well, I kinda know why.... Like I mentioned, the movement of the barrel does NOT have any measurable effect on "spin drift". But, the movement of a barrel or action in any rifle DOES effect (to a measurable degree...

I'm considering changing/trading barrels from a 29" to the CQ and I'm wondering if it's a pretty straight forward process and if anyone here has done it... Dan... Unless you already have someone willing to swap, I doubt you'll get any offers to swap "barrel assemblies" with you. I'm ...
