Well, I have been loading and shooting my 358 Win (Browning BLR) quite a bit since I have been home. I have been working with two bullets (Speer 220 and Sierra 225). With 48gr of Varget, it shoots about 1.5" with the 225gr Sierra. With 49gr of Varget it shoot about 1.25 with the 220 Speer. So far the Speer seems pretty accurate and with 49gr of Varget, it is pretty much a max load. I cannot fit anymore Varget in there. The loads show 0 pressure signs.
I also tried IMR 3031, from my Speer book and they were more in the 2, 2.5 inch range. Nothing has really flipped my wig yet. I am still waiting on my local dealer to get some AA2520 in and also some IMR4895 or even H4895. Anyhow, just wanted to let you all know how the load development is going for the 358. I am using CCI250's for all loads. I know I don't need them, but I cannot find anything else on the shelves. They have some CCI BR4's? but they are pretty expensive, and I would like to keep stuff somewhat similar. I would like to get the 225gr Sierra to shoot at about 1.25 or so. The BLR does have a fairly heavy trigger, but it is decent. Anyhow, I will let you know how it is going as I keep working it out. Scotty
