berger 215 hybrid in 300 rum

hi all, first post here. im from eastern WA and have been working with 215 bergers in my 300RUM.

I am starting to get some pretty good results so far i am at 90.2 grains Retumbo and 3.790 OAL. with rem brass and 215 mag match primers.

development group was 5 shots at 2 inches shot from 200 yards. 5 were about an inch group and the other was an inch away to teh left. i think it was me.

my next session i have same thing loaded but 5 at 90.5 and 5 at 91 grains.

my gun is a sendero with DE brake, action is bedded and wyatts mag installed. EGW 20 moa base and burris FFTAC 30 6.5-20 scope.

just starting out with longer range stuff outside 500 yards, but have hunted my whole life, bow and gun.

I have worked loads all the way to 95 gr of retumbo. Settled on 92.5 gr and going to start tweaking the OAL. Groups are at .7 100 yds. I expect things to get better at 2 and 300 yds. Shooting a stock 300RUM Sendero

Welcome to the forum! Excellent choice in a bullet for you 300RUM. I too am now running the 215 in my RUM. I previously used the 210VLD with great success but the 215 is a significant improvement with slightly better performance numbers at 1k than even the 230 Hybrid target bullet. My load is 92.0 H1000, Nosler Custom brass, Fed215GM mag primers and a COAL of 3.880" if memory is correct, this gives me .005" jump. My velocity is 3,140fps with less than 10fps ES. My gun wears a 27" lilja barrel. I don't believe you can find a bullet that will give you better long range performance out of your 300 RUM.

Re: berger 215 hybrid in 300 rum

Thanks tumbleweed! I have been reading yourposts. I was shooting the 210 vld also but only at 2870 and 90 grains retumbo. I am excited for the improvement of the 215. Looking back through my development groups most were all right around 1 moa and I have been working to improve my shooting with trigger control and breathing and form as well.
I am around 0.1 jump with these at 3.79 but they fit in my mag and I want to keep mag fed.
Ill keep updating this thread with my progress also.

Thanks again

Re: berger 215 hybrid in 300 rum

i went and shot the latest 2 loads this afternoon. wasnt very good.
las time i shot i was grouping a bit high so when i got home i decided to adjust my scope a bit... well i went the wrong way and when i shot today i was off paper... not good. i realized what i did before i shot the wecond load. and was able to hit paper. my group at 220 yards wasnt very great, around 3.5 inches. i am having issues holding steady ehile i am shooting. i am using a bipod and rear bag. when i aim i can see my heartbeat in the scope and am fighting small fast wobbles in teh scope. i only shot on highest power.
just need loads more practice i guess. for now i am going to stick wth 90.2 grains and just shoot some at distance and see how i do.

Re: berger 215 hybrid in 300 rum

I decided to stick with 90.2 retumbo ant coal of 3.800. Shot last weekend some. While zeroing at 220 yards I shot 2 toughing and waanted to see what kind of group I could get. Ended up at 5 shots in a 0.7 inch group! Very excited about that.
Also managed to shoot groups out to 875 yards. I was sub moa to 820 and was having a bit of trouble with wind at 875. Still got zeroed in and got my drops though.
Don't have a chrony anymore but with by ballistic calculator and all correct info entered (elevation, temp, pressure, BC, etc.) I came up with 2930 Fps which is right in line with Berger's load data. Can't wait to shoot some more!

Are the 215's any thing you would use on elk ? I see some are shooting the 208 A-max on deer and smaller.
