Just reading an older thread.

On the load and velocity above, that should not be taken as representative and perhaps the chrono reading was not reliable.

Why?

A 338/375 Ruger is in the approximate class/capacity as the 340 Weatherby. The 340 cannot safely send a 250 grain downrange at 3100fps. The 340 is more of a 2850-2900fps round. In fact, the 338 Lapua, with its much increased capacity, should not be expected to send 250 grains at 3100fps. The Lapua is normally rated at 2950-3000 fps with 250 grainers. Bore-riding bullets or long parallel throats could extend these expectations, of course.

Anyway, even though I love 416Rigby-based cartridges, I think that a 338 "Ruger" is probably about ideal for a 338 calibre and could have been the initial Winchester offering 50 years ago if it weren't for the silly belts that gave up all of the capacity in the case body.

Also Im About To Build A Modified 375 Verson Of This Im Gambling On It Pushing A 350 Gr Smk @ 2700 Fps. Argue It All You Will But That Isnt Going To Make Me Wrong. Going To try

Re: 338/375 Ruger?

A 338 Ruger full magnum would cover about 98% of the hunting that a 338 Lapua would cover.

Of course, everything is a sliding cline: a 300 WM would cover 98% of a 338 Ruger with proper bullets and shot placement, and one can go down the ladder a bit more, the 270 Win will cover 98% of the 300WM given good bullets.

But I'd much rather have a 338 WM (or bigger) if I faced an unexpected lion or buffalo.

So bang for the buck, ie., safety and killing punch for the dollar, a 338 WinMag gives maximum huntability for commonly priced rifles (under $800-900). And if someone did an inexpensive, commercial 338 Ruger, it would overtake the 338WM for all-around huntability on a budget rifle rig. In the meantime, Ruger and Howa have the 375Ruger for that niche. Sweet little rifles.

Just saying.

Go for it.
I'm not against trying, but I tend to lower my expectations to similar muzzle energies per cartridge. 2700fps may be pushing that 350 grainer a bit out of my safety zone, but I would probably expect the 250 TTSX to do 2900fps. I think of the 375 Ruger as an '4500-5000ftlbs' sort of cartridge.

I Also Have Advantage Of Being At 5,000' Elevation. I'm Not Sure About Pressure. I Will Just Keep Working Up The Load Till There Are Warnings Then Back Off. I Don't Know Any Better Way. Due To Books Under Rating Loads

Re: 338/375 Ruger?

Has anyone tried 300 grain bergers in the 338/375. If so I would be interested in the velocity and load data including coal.
Thanks,
Jon
