I have loaded 190 Nos CC, 208 A-Max, 220 Nos CC and 240 grain SMK.
I shoot pigs with them. Insane quiet out of a mod 7 with Omega can. Insane quiet. Pellet guns make more noise than this.
The 220 and 240 are preferable, but even the 190 at 1000 fps will exit a full grown (100-150 lb) pig and kill the pig next to it … *Almost every time.
The Nos CC are cheap to shoot but not fantastic at opening up, but, it does the job I need it to do. Kills pigs. Not always DRT, but dead somewhere else, which is preferable so I don't have to drag them off.
I did buy 200 of the 190 gr Sub-X loads. Have not shot a pig w it yet. I have loaded their 410 gr Sub-X in my 45-70. I'm very curious to see what this round will do to a pig! I have them loaded at exactly 1050 fps with Unique.
Have fun! A bolt action 300 blk is a perfect gun for that round.
