Due to the scarcity and inconsistancy of the info on the subject I would like to gather any info 50bmg precision rifle related in one thread. I have found it is difficult to seperate the m2 type data from the match rifle data out there.
I can edit data into the first post for easier reading...
1. 50BMG rifles shooting surplus BMG ammo or improperly sized ammo(for the rifle chamber) can experience hang fires/misfires. Due to the type of primer or the action binding the sear the detonation could be delayed or absent. It is critical that the operator understand the proper immediate action drills for their particular rifle to avoid death or serious injury.
a) Military primers can be less sensitive by design IOT prevent slam fires
b) Some Surplus ammo has tar inside the neck which causes tight chambering. This tight chambering can cause binding of the sear. The sear can release if the bolt is opened turning the bolt into a projectile.
2. Properly re-loaded ammo and factory commercial ammo are as safe and reliable as in any other cartridge and and can provide excellent accuracy and long range wind resistant performance. The same rules apply as to any other cartridge
3. The 50BMG rifle has been replaced in many LEO/Military roles by smaller more man portable platforms in 338/300 calibers. The 50BMG as a precision rifle round offers many desirable characteristics if portability is less of an issue such as in civilian competition.
4. Popular re-loading powder are:
- H50bmg
- US869
-
-
-
5. Popular projectiles are:
- Hornady AMAX 750 grain
- lehigh solid match
- M33 pulled
-
