New upper range report
Posted: Tue Aug 07, 2018 7:56 pm
Got a Bushmaster 20" upper and finally got to take it to the range last Sunday. Took some Hornady Black ammo and handloads of 225FTX/38.0 LG/R7.5.
I used the BM mag (7 rd.), a modified (front "rib" removed) Pmag, and an aluminum GI-type 30 rd. Pmag wouldn't feed. GI worked OK, though I didn't put more than 5 rounds in. BM worked OK, but not great. Overall, disappointed with function, but I realize it's new and will probably work better with a higher round count. One of the Hdy. rounds refused to light off after multiple attempts.
Hndy averaged 2209 for 10 shots. 225's avg'd 2261. Extreme spreads were 194 and 187 respectively. Groups (5 rounds for Hdy, 10 rds. for mine) were about 5" and 3" at 100 yds using a 4X scope. (I'm capable of better, so my "excuses" are very gusty winds, no sandbags, and some recent short-term eye issues. Also the bullseye I was using was small enough that the reticle covered it.)
So, all in all, I'm disappointed with the accuracy. and not impressed with function. I may try upping the 225 load to see how that affects accuracy and internal ballistics.
Any suggestions or perspective will be given due process.
