1:8 twist, 20” barrel, Varget powder, 2600 fps. I used hornady data for 80, 88, 90s for a starting point. I’m running Varget powder and was over book max on some with no pressure signs. Had loads going 2525-2700. My gun shot a load that was 2600 fps really well so I just rolled with that. My limiting factory is mag length with a howa mini I’m at 2.315 COAL to get them in my magazine. All these loads were 7-14 SDs with 10 shot groups. Once I get a 223 barrel and bolt face for my PRS gun I’m excited to load some longer and see how they are out of a longer barrel. Be a fun round for a trainer.
