@alphapygmy , I still have those 12 x 12 x 1/2" AR500 plates we talked about when I bought the three barrels from you. Lemme know if you want one. You're set with RL33.... I have a few lbs of it but haven't tried it yet.
Love to have a plate! PM sent
33 Is the powder for the 338 Lapua, especially with the heavy bullets. I have shot a variety of powders in my IMP version. RELOADER25 was ok for accuracy but I couldn't get the velocity and it was real hard on the brass. H1000 was a little better but still couldn't get the velocity I wanted and it was hard on brass. Anything faster then those powders and you won't be happy. At the price of the brass, I would really try to find Reloader33. I don't think you will be happy with the performance of anything else. MattStarting to work up my 338 Lapua and having good luck with RL33 and Hornady 285's and Berger 300's. I only have a few pounds of RL33 and no more available so I'm looking for a backup powder. I have some H4831SC but that's about the next slowest thing I have. I can get a little RL26 locally but no H1000 or Retumbo. What faster powders have you ran in your 338L with the heavier bullets?
I woukd try the bullets in the lands. My Lapau's all shoot better that way. MattHas anybody tried IMR-7977? The load data on Hodgdon's site looks promising, but I haven't heard of anybody using it. I want to try something other than RL-33; I have a good supply of it, but all the groups are MOA+. I think the factory RPR barrel may be part of the problem, but it's going to be a while before the replacement comes in.
VV powders are pretty scarce even in good times around here- central Idaho.We have been working with the 338 Lap Imp for the 2k match. RL33 is good. N570 has been even better.
