[QUOTE="eshorebwhntr, post: 2377545, member: 17112"] Based on what I saw in a couple 7 mags I think you'll do well with 4350. I think the book listed max was around 59gr for 140 class bullets. I started to feel slight resistance in bolt lift at 65gr. Stopped at 66gr. 24" barrels were seeing around 3350fps. I think you should look at book data for 140s in a SAUM, start at or near the top, work up and find pressure, then back down a touch off max and look for accuracy. They were pretty easy to work with for me. [/QUOTE]
