No on the SW4350. Have used Precision and Berger 105 Hybrids with great results. I believe SW4350 might be a tad too slow. SW Long Rifle shot pretty good out of my 6BR.
@Perk: I know one PRS guy who run Hodgdon 4350 in their PRS 6mmBRs and swear by it. I gave it a try in my 29" barrel using Lapua, CCI 450s and a 105 Berger Hybrid.
Mostly I wanted to see if there was an advantage in velocity and there was. 33.2 grains in my barrel yielded 2908 FPS with no indication of pressure. I shot 3 5-shot groups and saw SDs of 5.1, 8.2 and 5.6. Not great but, not terrible either. Group size at 100 yards was .47, .69 and .79 MOA. I didn't do any further testing. it was about 40 FPS faster than a 30 grain Varget load and wasn't worth the extra load development for me.
I am assuming that the SW powder is reasonably similar to H4350 based on what I've read on the Internet.
Hope that helps,

SW 4350 is supposed to be the slowest of all the 4350 powders. But if you have it, try it. Now days you shoot what you can get, not what you want.
