A QuickLoad request for a .30-338 Lapua Imp. please

[IdahoCTD]

If someone can manage it I'd like a Quickload run on my .30-338 Lapua Imp. with 230 Berger's and WC872, 869, R-50, R-33, and H5010 powders. The water capacity is 123.5grs to the top of the case. It's a standard 338 Lapua necked down with a 35 degree shoulder angle and a .572" shoulder dimension. I ran up to 111grs of 872 last weekend and got 3333fps out of the 230 Berger's (it's a 33" barrel) but I'd like to try R-50 and H5010 to see what they do. I'm not a huge fan of ball powders but some cases will only get their top velocities using them. It's plenty accurate with the 872. It shot 5 of the 7 shots from 108grs to 110grs into the low .2's. One was a clean bore shot and was out about 3/8" and the other I pulled. Not bad for 3 charge weights and 104fps variance.

Here's what's there.
I used the overflow capacity you gave and a 33 barrel.

Bullet : .308, 230, Berger Hybrid G7 #30428
Useable Case Capaci: 112.134 grain H2O = 7.281 cm³
Cartridge O.A.L. L6: 3.720 inch = 94.49 mm

I appreciate it. I'm amazed at how low the velocities are. Guys are getting 3175fps with 230's in a 26" barrel using 110grs of 869. One guy has a Oehler ballistic lab and keeps it to 65kpsi or less.

 

[Dwh7271]

I set the pressure max at 64k
I would imagine you can monkey w those a little. Rifle will probably tell you when you're pushing it.
I used your overflow number though.
