Re: 338/375 Ruger?

I'm in the early stages of testing a 338/375 Ruger. Weapon is an unmodified Sendero in 300WM rebarreled with a 27 inch, 1-9.0 twist, 1.250-.825 taper Satern barrel.

Here is a current list of data fired, I'll update every few days as I shoot.

All initial 225 Accubond loads use 215M primers and OAL set at 3.510 to use magazine.

nosler 225 accubond

RL-22, 85.5gr, 3146 fps (close to max in my weapon)

IMR 7828, 83.5gr, 3067 fps (low pressure compared to RL22 load)

H4831SC, 82.5gr, 3021 fps (primers slightly flat)

Still have Hybrid100V and few others to test.

300 sierra matchking OAL changed to 3.650, still 215M primer

IMR 7828, 75.0gr, 2623 fps (initial 300 gr load, would like to make 2700 fps before overpressure)


I've used BR-2 primers with similar charges under 90gr in similar cases so I'll try those next along with 250 AB's and MK's.

I'll be watching with interest as well. Could be an interesting creature.

Re: 338/375 Ruger?

I too have built a 338-375 Ruger. Dave Manson made the reamer and has the print on file. I built it on a long action 700 and a Shilen select match 1:10 twist barrel, but haven't put it in a stock yet. It's one of my favorite projects though, so as soon as I have the cash I'll buy a stock and get back to work. I'll try to keep everyone informed as I don't think Rick Bin is ever going to write part II of his article on the ".338 Campfire".

Still working on getting time to load up my first batch of rounds using 200 gr Hot Cores.

I'll get back to you.

I just finished my 338-375 ruger rifle. And have been quite impressed. Using a Howa 1500 action with a 26" 1:8 twist lawton barrel. My load work up is 93 gr. Vihta Vouri N570. Horandy 250 hollow point boat tail. Its chrono speed was 3120. Minimal pressure signs were seen
