Re: 300 RUM and Retumbo

Would you guys consider it acceptable as long as you got over 3000 with a 200gr bullet and got good accuracy ? Or do you like your rifles to run at top speed ?

Re: 300 RUM and Retumbo

I always wondered why anyone would own a 300 RUM and shoot it @ 300 Win or 300 WBY velocities. There's certainly nothing wrong with doing it, it just seems odd to me.

However, I did notice that many posters are quite happy to get good accuracy even if the velocity is 200 ft (or so) less than the maximim listed velocity.

Re: 300 RUM and Retumbo

The reason I got a RUM was for velocity and range. You can back it off but why not just go with another cartridge and save a lot of powder and some recoil? We all have our priorities and goals. I can get 3200 fps with a 180 bullet out of a 300 WSM and 3400 out of the RUM with a lot more powder and recoil. I have considered quite a bit if it's worth it. So far, I think it is.

How are you getting 3200 with a 180 gr bullet out of a 300 WSM ?

Re: 300 RUM and Retumbo

Tang,
I shoot the exact load you want, shot a mule deer in 2008 year at 485 yards. 200 grain sierra game king 95.5 grains of retumbo oal is max in ur magazine. however the 200 game king is an elk bullet as far as im concerned it has a thicker jacket and more antimony in the lead. shot 1/2 inch groups all day. last year i went to the JLk vld 210grn. long boat tail, higher bc, at 94.0 grains of retumbo. oal 3.745 its a deer slayer. high bc. if u love sierra try the new 210 vld sierra matchking or 220 grain match, but don't shoot deer with 240 matchking they won't expand on deer at long range. I like that 210 JLK LBT, they use a J-4 jacket like berger.

With 67.5 of RL17. The actual average velocity was 3193 out of a 24 3/8" barrel - 1" less bore length than the RUM.

Re: 300 RUM and Retumbo

I agree on getting the speed. I have a .300 Win Mag already. Odds are, I might not ever need something bigger than a .308 Win, but it's nice to know I have it if I do need it. I do sometimes wonder if I should have ordered my Sendero in .300 Win Mag.

But, Im trying to obtain 3100-3150 with a 200-210gr bullet, and get 1/2" or less groups. I'm working with Retumbo, Fed 215 GM primers, and Rem brass.
