300 RUM loading results today

[PA Hunter]

200ab, and retumbo.

Haven't seen a 300rum that wouldn't shoot that combo

I load for 5 different. 300 RUMS and i load 200 Accubonds with Retumbo or RL 25. Interesting though the 200 Accubonds all group better than the LR Accubonds.

The LR’s are 210 correct? and I have heard that before

Yes, the ABLR's are 190 and 210. The regular Accubonds are 180 and 200.

Not the same cartridge, but my .338-378 shoots like garbage with both Retumbo and H1000, which to most are some of the best powders there are. Reloader 22 and h4831 have been very good to me

Until recently, I’ve only shoot 200ABs from my 26” barreled 10 twist 300rum. It shoots ridiculously good. For some reason I can’t leave well enough alone, so I picked up a couple boxes of 230gr otm tacticals. I found accuracy without pressure at 3095fps average with 91.5gr of N570 and low single digit SD/ES. I am at 4000ft altitude, though. You should look into this combo. The 230s have been popping up recently and N570 was available for a couple weeks not long ago, so there should be some around to trade/buy for.

Getting ready for my first Elk hunt in 2 weeks (CO 2nd Season OTC Unit). I put a new stock on the 300 RUM, a Manners PH. And, I bought a dedicated scope for the RUM instead of moving scopes around onto it constantly. Mounted a Bushnell LRHS 2 to it.

Sighted it in Wednesday this week, and got an an acceptable 1 MOA group. I'd like better, but I think this is the best I am getting from this big a rifle and factory ammo.

Using the 180gr Norma Bondstrike ammo. Chrono'd this ammo at over 3300 FPS using my Garmin Chrono.

Now to bag an Elk....
