Regardless of what bullet material used stick with a RN or RNFP (aka "cowboy style") and you'll have no feeding problems.
WRONG, WRONG, WRONG in lone wolf barrel.
The only lead bullet to function was 230 gr, round nose in my lone wolf barrel, but the others ( 185 and 200 - LDSWC or RNFP) function perfect in the glock barrel and also my 1911. I use Berry Bullets with No Problems.
I have to other lone wolf barrels 40 to 9mm for a G22 and 357sig for G35 and have use all weight of bullets and all have worked well. I love the 357 sig barrel, it's a fire breathing dragon!!!
