116 TMK, 2.90coal, 6CM, 16.5” PBB 7.5” twist, Hornady brass, Fed210. 100rds on the 16.5” barrel at this point.

42gr- H4350-AV 2759-SD 1.5- Slight Ejector mark. Drop to 41.5 and fire 10 next time.

44gr- H4831sc- AV 2682- SD 25.

43- N555- AV 2739-SD 14. First shot was the one not hitting the dot, this is the worst test group I have ever had with N555. I will likely redo this.

43gr- Staball65- AV 2745- SD 18- Ejector marks. Drop to 42.5 and fire 10 next time. This is the best group I have ever had with this powder.

47gr - H1000- AV2809- SD 28- Stiff bolt + ejector marks.

16” 6dasher .104” freebore Howa Mini factory barrel. All fired as fast as I could shoot steady from bench. 80*F, very windy

Alpha 3x fired brass

116tmk

3x each 2.35” 31,31.5,32gr Lever, 1x each 2.4” 32.5, 1x 33

.150 and .100 off lands, respectively.

All shot at same POA.

31,31.5 bottom cluster, 32 top left 3, 32.5/33 top right impacts.


31: 2510fps avg
31.5: 2525fps avg
32: 2600fps avg
32.5: 2625fps
33: 2675fps


33 felt a little hot. I don’t want to shoot these bullets,but I’d probably load at 32gr, maybe 32.5gr if I could load out at 2.5-2.6”
