Hey LRO!

I was wondering if anyone has any load data for a 300 RUM shooting 230 Berger Hybrid bullets with RL 33?

Any help is much appreciated.

Thanks

I shoot a 30-338 Norma Imp (which is just over 110grs of water capacity or slightly less than a 300RUM). My load is 91grs of R-33 in Norma Brass and 92grs in 423 Dakota brass of with a 230.

Start at 93gr and work up. I know guys that end up over 100gr, but YMMV

Developed loads for and shot many 300 rum's however none with RL33. Retumbo once but mostly with H1000. Having said that, I found that the max I ever could shoot was 89.9 H1000 using the 230's.
Berger is really cool to provide data and will do such via a simple email, ask for recommended load for the specific bullet, generally they respond within a day, often faster, It's safest this way. Obviously start low and work up.

Appreciate you recommendation. I have emailed Berger and they are very fast to reply! Just seeing if there was anyone that has had success with that powder and bullet. The most common from my little research is the H1000 and Retumbo...

My 30-338 Norma Imp shoots the exact same velocity with a 30" barrel and 91 or 92grs of powder depending on the case I'm using. It is stupid accurate too. 3 shot groups in the .1's and 5 shots in the .2's is the norm. My OAL is only 3.608" though.

I shoot the 230's with 101 grains of 33. Fps is high 3100's. I was shooting 102.7 grains but it was super hard on the brass. My gun seems to really like the 230, and likes the 33 even more. Great combination. Word of warning however, in my tests I've noticed that 33 is sensitive to just about everything. Temp, elevation etc.

Thanks guys!
Jayson is the 101 grains considered a compression load? What type of grouping/yardage have you shot? What is your OAL? Thanks

That's a good question?? 99 grains in my two rums was too much. Unless the rifle is throated really long, they have to be redlined.

I'm running 101.3 of RL 33 at 50 thou off in a heavy contour benchmark 28" tube. I'm over 3100 fps and got up to 3230 at 102.7. Max Load though! There is no "crunching" of powder however I would say that is compressed. My OAL is 4.0 with the help of a Wyatts mag box. This load is indeed....redlined.

Range results from yesterday say that in my rifle, with brand new Nosler brass, .025" off the lands, 3.9" OAL, 101grs of RL33, , CCI250, gets 3140 fps avg, 16 ES, shoots about an inch for 3 at 200. I'm thinking that after they have all been fired the ES and accuracy will clean up a bit, maybe grab a touch more speed as well.

Thanks Jeff!! :)

BTW, I'm not sure if you remember but you helped me pick out the 230 Bergers when they first came out in '14. I still appreciate you advise. There's been many dead animals that haven't.

I'm sorry I forgot to answer your shooting distance question. My longest successful shot came in WY 2 years ago with this combo. 1660 yards. I haven't had another opportunity like that since.

Excellent video!!! Thank you for sharing that. It's definitely hunting season soon, 48 degrees in ND this morning!!

Backed it off to 100.5grs, avg 3206fps 7fps ES, half inch groups at 100, bumped it out .015" as well. I'm pretty happy there, I just hope the bullets perform on game for me.

I'm not using the berger like many of you but am using the 225 hdy hpbt. I am at 95 grains rl33 for right at 3,000 fps from a pair of 26" factory tube 300 rum rifles... I suppose I could chase a few more fps but on hot days I already get a touch of brass flow with a hot rifle and a bit of resistance on extraction. I'mk not one for beating up rifles for a few fps so I've left it alone...
