300 RUM/210 Berger/Retumbo... how many grains do you use?

[MtnMuley]

You should give the 190's a shot.  94 grs of Retumbo works well for me.  I swore that I was sticking to the 210 in that gun, but gave in to the 190's after their preformance.

Alrighty, so I tried 92.5 grains of Retumbo, Nosler Brass, Fed GMM215 primer and Berger 210 VLD out of my Rem 700 with 26" barrel.. I got about 100 FPS faster vs my old load of RL 25. Average of 3050.

That being said, results were about 1.25 MOA.. where with RL 25 I was shooting clovers.

So.. Im sticking with what I got.

Gonna try the Retumbo with the 200 Grain Nosler Accubonds.. they did not seem to like the RL 25 much, but perhaps with the Retumbo they will be straiten out.

Just curious, How much RL 25 are you using, is the load compressed at all?

[MDGrand]

Hi, BearPaw...

87.9 Grains of RL 25 gets me 2950 FPS and about .375 MOA. It is not a compressed load, but admittingly I am over recommended max grain from Berger. I have seen NO pressure signs whatsoever though and I have fired a LOT of these rounds.

Hmm.. Perhaps I will try that. I have pretty much wanted to stay with the 210 as well because of the rediculous BC.. but the BC out of the 190s is super high too.. (0.57).

Thanks!

We use 92 grains of H1000 with 200 accubonds and they shoot real well in our guns.

Hopefully you are still around.  I just bought a 300 RUM  700 RMEF.  What load did you end up with?  any advice will be appreciated.

[MDGrand]

Hi, Ironhead, its still somewhat of a work in progress. After anothe trip to the range the Retumbo got to about a MOA if not a bit under. The RL 25 is still working well, but at longer distances I am wondering if the FPS variance has changed a bit because my trip to the 600 yard range my shots were a bit high.. grouping but a bit high.

Just a tip.. if the 300 RUM RMEF rifle you got came with the same plastic hollow stock as mine did... do yourself a favor and go to stockysstocks.com and pick out a drop in replacement. The kick on that rifle is good enough that your finger will bang against the trigger guard. Plus, accuracy cinches up a bit more with that.

Good luck!

I made the switch to 215 Berger hybrids using 90.2 grains retumbo and oal of 3.8 shot a 5 shot group at 220 yards that measured 0.7 inches. Have held sub minute to 1000... shooting at 2950. Same powder charge nets 100 Fps more with 215 than 210 for me. Better BC (.696) also.
Just a thought. I have 60 or so 210 vlds if you are interested in buying I could part with.

I am just getting started with this round.  It appears that you have yours dialed in pretty good.  If I can even come slightly close to your numbers I will be thrilled!  I will be heading to Alaska for some hunting in the fall.  Winter will be a good time to play around and get a good load worked up.  I can shoot out to 450 from my living room!  No mop squeezer here to complain about the noise!  Thanks for the info.

try calling the guys at " best of the west" they shoot the bergers and im pretty sure they use retumbo also they might have some info for ya

[MichaelJ]

I would trust Travis (Rbros) advice over any info you'll get from the Best of the West guys... imho they are there to sell rifles and scopes, and most of their guns they sell won't hold better than 1/2 MOA on 5 rounds.  Just my opinion but maybe they do have a decent load for you.

Have u shot there rifle on paper ever?

[MichaelJ]

Have a friend with one in Moses, and my college roommate had a hunting partner that hunted with one as well. Both were about 3/4-1MOA guns.  For the money you spend on their rifle you could get better components and more accuracy from any competent gunsmith.
Why do you think you see them with hunters all the time and never at any kind of rifle match?  TV and the internet sells...

 Ok I was just wondering Ive never shot one of there's the only thing I've ever heard was from them haha and we know how that is they will say its the best gun ever made just to get u to buy one

[TheHunt]

Interesting... My son's 338 RUM really, really likes 96.4 grains or Retumbo with 250 gr. HPBT MatchKing.

I have not tried the Berger 338 300 gr Match Hybrid OTM Tactical bullet yet but I am betting it will be a good shooter as well.
