[QUOTE="benchracer, post: 1454118, member: 22069"] Based on the above results, I had loaded a MIN-MAX runup with Superformance and 250 EH @ 3.555" in Norma brass. I loaded in one grain increments from 65-69 grains. I finally had the opportunity to shoot them yesterday. Temp was 95*. The first round in the series, the 65 grain load, gave hard bolt lift/extraction and an ejector mark. Velocity was 2862. Of course, I didn't fire the others in the series and pulled the bullets. Looks like I will be doing some testing below 65 grains. If I find some accuracy with this, it would certainly be nice to have another good powder choice. [/QUOTE]
