I'm running low on H4350 as well and want to use up the remaining on my 140 bullets. I have some TS 15.5(which is probably harder to find than 4350) that I just tried with 120gr ELD_M that I have. 24" barrel with a 8 twist and usually shoots .5 moa on good days. At 42gr I started getting hard bolt lift but no other pressure signs.
@Bill Norris I like your target, thanks for posting it.
