reloading data 300 rum

[Tyler Holderby]

Hey fellas,

Wondering if some of you would help me with my first reload project, I'm shooting a 300 rum sendero, 210 vld, retumbo power...what would be the best recipe for this?? and OAL?? Thanks in advance

I've done 89gr and 89.5, and oal is 3.60 but i'm not happy with the results

My go to load in my RUM is 93.5 grains of Retumbo lit by a CCI 250. My COAL is approximately 3.75 which is .015" off the lands. This load has proven to be 1/2 MOA or less to 1,000 yards at 3189 FPS. As always work up from a lower charge but it is safe in my gun and my brass is on its 7-8th firing.

with the 210??? or a lighter bullet. 26" barrel?? I can't get a 200+ grain that fast without high pressure in my 30 rum. I do run 225's at 3K no trouble though.
I really haven't played with the berger though, mostly sierra and hornady.

Yes with the 210 in a 28" 10 twist barrel. I've been using Nosler brass and it's been treating me very well.

O.K. you're getting a bit extra on the barrel. I have a factory 26".
The ultra brass takes a pretty good beating, whether rem or nos. I'm still using some 7rum brass necked up that I tired out the last rifle on.
