Does anybody know the BC of ACME 265gr 300blk bullets? There's no published data on their site and I'm trying to figure out some stuff on paper before I go out to the range. I tried this load at a block shoot on a bear-sized target (standing) at 200yds and wasn't able to even get a hole on paper (all I had the last time was a 2 MOA red dot zeroed at 100yds with 150gr Federal ammo).
I now have a Vortex Venom 1-6 LVPO on my Ruger American 300blk. I have it zeroed at 100yds with 150gr Federal ammo. To hit a 1gal milk jug with the 265gr ACME bullets at 100yds with BDC holdovers, I need to put the top of the milk jug at the 500yd BDC line (calibrated for 55gr 5.56mm ammo), so roughly 10-11 MOA of elevation if I use the elevation dial. Easy enough, but I want to know how this scales to 200yds - How many MOA do I need to come up from my 150gr/1940fps zero to make a 265gr/1050fps ACME bullet hit the vital zone on a bear-sized target at 200yds?
To get close, I need the BC of the ACME bullet. And I don't have a 200yd range to get it right so I need to use the math and hopefully get close at the next block shoot.
And once I shoot all 250rds of these ACME 265gr bullets, I'm never buying them again. It doesn't feed reliably and jams every third shot in my Ruger American Ranch - that flat point gets stuck almost every time unless I run the bolt hard and fast. And I'm experiencing bullet setback issues where I'm not sure if it's safe (but velocities are actually VERY consistent regardless) I really wish they would redesign the bullet with a round nose for more reliable feeding in bolt guns. And furthermore, I'm not so sure that the coating makes them safe to shoot through my sealed/welded suppressor.
For reference, my load is 265 ACME w/11.0 grains of CFE BLK seated to 2.120" with a velocity right around 1050. I don't have my Garmin Xero handy, but from memory the extreme spread was <12 FPS with this load, with SD in the single digit range. Perhaps my memory fails me but that's what I recall.
Have I mentioned that I'm new to all of this and having the time of my life?
