Hi, I have a 450BM with an 18" tromix barrel/bolt and just completed Hoot's CCWS on a new M16 style bolt carrier! Also modded the ejection port with posts from here!
I figure the weight should stay put as the M16 style bolt carrier has even more surface area than the AR15 BC to adhere to. Hoot is this mod still holdig up on your rifle??
Question: Maybe this has been done in the past? Has anyone ever tried using a cannelure on the 230g fmj or 250g FTX, with either a Taper crimp at the top of the case or a stab crimp down lower?
I am seeing bullet pull after just one bolt cycle...even with Hornady 250FTX factory ammo, so I am trying to eliminate it on my reloads.
But the gun is MOA with Hornady factory ammo, so is there some reasonable explanation on how this works? I would think that .001-.002 bullet pull would add enough variation to cause problems?
Also a Big THANKS! to Hoot and the Crew for their informative posts here for the 450BM
I would not have gotten this far without em!!!!
Thanks!
