OT- New IMR 8208XBR Powder

[336A]

IMR has a new powder coming out called 8208XBR, it is part of the extreme line therefore it is very temp insensitive. I'm thinking about giving this powder a try if can find it, seeing how I have had rotten results with W748 and Rl15.

336a,

I haven't seen any of that new powder in central IL. But then I wasn't looking.
What kind of bad results did you have with 748? Just curious because I've used it with complete satisfaction for oh going on 40 years now.

Here is a target that I shot using W748. I was shooting at the lowe right bullseye, you will see one round on the bull and the 2 other shots almost on the one in the upper right . My results with RL15 are identical to what I was getting with 748 The rest of the groups were shot with 150gr Fed Fusion and Hornady 160gr LE ammo.

Hmmmmm, something didn't work right with that load. That's for sure.

They don't all work the same in every gun that's for sure. RL15 has given me some little tiny groups with quite a few rifles. 22-250 to 35 Whelen. You never know.

Hi Nath, no it is a 2002 vintage Marlin 336A. It is kind of funny weird because I thought I did something wrong when loading those rounds. A buddy of mine was with me and he had a 336a as well. I let him try some of the loads and his rifle shot them like they were made for one another. I'm guessing I just need to find the right powder. After reading some articles by Biran Pearce I'm also leaning toward H322.

Or the right primer, when your not playing on the edge, sometimes it's that simple to go from bleah to wow. Try at least 2 other brands of primer in it before you give up on the powder. I've seen it work too many times.
