What ammo are you using on your AR-50
Since there are a lot of AR-50 owners here. What ammo are you using and what type of groups are you getting with that ammo.
I am still breaking my barrel in, so i am using CBC.
I shoot everything in my AR-50, you can expect the usual 2 MOA +/- a hair depending on who made it and how hot it is from surplus. Reloads will vary on how much time you spend on prepping eveything and if you're using surplus or match components. Match stuff will get you MOA or less consistantly as long as you do your job behind the trigger. Reloaded surplus can get you MOA but that's on the rare occasion that you find components good enough to do that but you can expect to see a little over MOA.
When Talon was still in business I shot a 12" group at 1K yards using their remanufactured surplus, with AMAX I can keep them under 10" inches but being an off the shelf rifle the norm that I've found is right around 10" on average.
Like children, good ammo starts at home.
Once you work up a load you'll never go back to "store bought" 50BMG ammo again.
Pmc, american eagle, cbc, & barrett. Always about 2-3 moa
I've shot lots of surplus thru my AR-50, but made sure it was "clean" surplus.
The mil-spec chamber with an inch of freebore helps to prevent over-pressure from damaging the rifle.
Newer AR-50's may have an issue due to tighter chambering specs.
For the BEST accuracy, you must reload.
In the June 2010 Spring FCSA Match at Alliance Nebraska I shot a 5-shot group under 5 inches center-to-center at 1000 yards, my first Screamer!
I was shooting Lehigh 510-130 solid brass bore-riders over 235.0 grains of VV 20N29, using heated ammo at firing line.
Have fun with yours, but remember 2 things: BE SAFE and get TRIGGER TIME !!!!
