[QUOTE="AKBman, post: 2298374, member: 898"] I recently purchased 250 pieces of Peterson 300 WM Long Brass, I have been searching for more Norma Brass, but looking at the reviews I thought I'd take the plunge. It seems to be softer than my Norma Brass, and it certainly has less capacity. I loaded up 20 of them with 208gr AMax bullets over IMR4955, lit by CCI250s. Accuracy was as good or better than loads with the Norma brass, but I started seeing the ejector imprint 3 grains under the max load. I am shooting these in a factory Sendero, and so expect a little more velocity than some of the book loads using 24" barrels. At 2 grains under max, my velocities were 50fps over the expected velocity for the max book charge. I didn't notice the ejector imprints until I got home, very faint, and almost identical across a 1.5 grain increase in powder charge, the primers showed some cratering in the last rounds fired. I know that 4955, which is in the same ballpark as 4350 in burn rate, but it is the powder that was available to buy. I am going to try some RL 26, as I have a pound of it, and I have a bunch of Magpro left in a Jug I got a smoking deal on, I just don't like shooting it in hot weather. I also have a little RL22 on hand. Anyone else using this 300 WM Long brass seeing the same thing, am I over thinking this? Bolt lift and extraction were perfectly normal. [/QUOTE]
