My reason may change to 'not a problem anymore' when I get the charge holes chamfered. I had a friend let me try these 357, LBT, 160gr, LFN-GC - Montana Bullet Works I do believe I could throw a speed loader full of these from across the room and they would drop in. He uses this bullet to hunt deer with and seems to be happy with performance out of a 7.5" Blackhawk.
Matts has a non-gas check 160 Grain Round Flat (.359) [359-160-RF] - $17.00 : Matts Bullets
I have about 30 left of the Montana bullet. I have been working up loads with 2400 I am in the mid 1100s with 14.5gr(3"guns) and still have a grain to go to hit max. 1200fps seems obtainable. The accuracy seems to be a bit better than SWCs but it could be that I am just shooting more. I will have to do a side-by-side comparison.
Cost wise, I may see how Matts do for training as Montana is not accepting order right now.
