I wasnt asking any quesitons, I was giving you facts. You obviously dont know what youre talking about. Having the knockdown power of a 45 in a rifle is NOT knockdown power for a rifle... Thats pistol knockdown power IN a rifle when shooting subs.... Unless for fun, no use, no shine.
Shooting supers at 2150 with a good expanding bullet has more than DOUBLE the knockdown power then your subs....So you can compare for yourself, here is Black Hills 300blk ammunition page for 1 source of reference...... Their 220GR subsonic ammo has 537ft lbs of energy...... Their 125 TMK supersonic ammo Im referring to has 1224ft lbs of energy...Big difference Like I said in my previous post. 300blk subs are for fun...

Ive done some pretty extensive testing with 300blk for accuracy and expansion 4-5 years ago. You may LIKE shooting subs, but from a useful standpoint, they dont compare to supers. Also, 300blk supers are quiter out of my 10" 300blk than 5.56 out of my 10.5" 5.56 by a very noticable amount. Now Im testing and talking about practical use, not fun range toys.
Here is final load confirmation after doing a lot of accuracy testing across 5 300blk barrels 4-5 years ago then expansion testing. This 125 TMK expands like an HST, retaining all its weight and opening up into a nasty flower pedal. I gotta find the expansion pictures. I tested 200, 220gr and various 110-125gr bullets. The 110 TSX and 125 TMK are the only ones that expanded. Thats my 10" SBR 300blk 7 five shot groups @ 100yds from the bench, bipod and rear bag with a Vortex Razor Gen1 5-25 to confirm accuracy with the final load.
For some background, I refused to get into 300blk for many many years. I kept hearing its not an accurate cartridge, its a fun gun to shoot subs very quite on steel at the range. I set out with a goal to prove some people wrong. I wanted head shot accuracy from 100yd and in with supers. Home defense/truck gun with eyeball accuracy. I have to say, I didnt think I was going to achieve my goals and almost wrote off the 300blk and agreed with everyone telling me it wasnt an accuracy cartridge. I went through 3 barrels from top names and they ALL shot between 1.25-4moa... Not what I was looking for. I decided to test 1 more barrel and it exceeded my expectations. The Rainier Ultramatch 10" 300blk... It wasnt even close. You can see the 0.521" aggregate @ 100yd over 7 groups (35rds). Thats DAMN GOOD for ANY AR, let alone 300blk SBR... Even though I had no intentions of shooting it at distance, decided one day to see how far I could walk it out. I went 10 for 10 on 12" steel at 200, 300, 400 and 500yd no problem. It was dead on with my LPO on 5x.. I have now had 2 of these same barrels and they both shot exactly the same with the same load. Just to give some background.
