Berrys 125 gr .357.

I use them with Bullseye or Accurate #2.

I've shot them with 3.8 grains of 231. Much cleaner than Trailboss.

Nearly all shotgun and pistol powders will work well with that bullet.
I used universal, titegroup, and 700-x

I've used them in 38spl over 4.4gr HP-38 using S&B SPP and they shot well out of my S&W Model 10. Last week I tried them in 357 cases with 5.7gr HP-38 using S&B SPP shot out of a Ruger GP100. I've used the Xtreme 125gr FP using the same data and I don't notice a difference. I'm happy with them so far.

I get better accuracy from cast & coated bullets with a good crimp groove
