Yes I would think so with 129gnr's. Excellent shooting.

Fireforming. Mixed success I guess. Worked up to 15gn AP70N plugged with cleaning cloth...which has to pushed all the way in not just tucked in the neck (in case anyone is silly like me). Not sharp shoulders but all set for full 260AI load.
10 grains:

I used 17grs of AS-30 nice sharp shoulders.
What powder have you found the best so far?
I could've gone higher may be but was worried I'd stuff the primer pocket... @7mmsaum should I go hotter?
I am only using RE17, and have a tub of AP-70.
Would love some more RE17 if any one has some.
@25/08IMP AP-30 is their fastest powder so 17gn means I have room to move I suspect.
Abe tried 14 up to 18 grns when he did my barrel 18 had a slight ejector mark but 17 was fine and a 2" square patch pushed hard over powder.

Went to 19gn and no real improvement...very hot suppressor.
I take it off and point it into a big bag of rags.

Hahaha
Yeah I didn't use the cloth with the suppressor...was loading and firing out of gunroom window as I went...upside of rural living... the 0.25" squares were gone before the end of the barrel but decided against chance.
A 'load' of drama - fire forming [emoji41][emoji41]
Yes that fire forming load can go hotter to sharpen up those shoulders, and lube the outside of the neck and shoulder with Redding sizing wax, this helps the shoulder form even easier without chamber wall friction.
@Tikka7mm08 what's the latest on this front? Tried any of those 143gr ELD-X in this machine yet?
