338 RUM and 213 Hammer Hunter

[jamiebolseth]

Hello,

Just got a rifle rebarreled to 338 RUM (very reputable builder). 9.4 twist Proof carbon barrel at 24". Running a TBAC 33 Ultra suppressor as well.

I tried the Hammer 213 grain bullet with RL26. Accuracy was "OK". Worst group was just over an inch. Best was 0.7" with averages around 0.9". Not quite what I was looking for in a long range hunting rifle.

For what it's worth I had a few 250 Accubonds that I loaded up just so see how they shot with RL26. Both groups were right at 0.9 as well.

Wondering if anybody has found a good recipe with this bullet in 338 RUM, or Edge, or 340 Weatherby? Probably going to try a different powder, but there's not a ton of data out there for the 213 Hammer.

Thanks in advance.

The Nosler load guide for RL-22, and H-1000 are where I would start.

Sounds consistent? Small tweaks in equipment, and or technique worth looking at.

How many rounds down the new barrel?

 

[jamiebolseth]

Barrel's only at about 40 rounds. So it very well could settle in more.

Technique is always a question as the 338 RUM is a little friskier than my other rifles. But I shot an identical build (same stock, barrel, action, scope, trigger) in 7 SAUM today and shot 2 consecutive groups in the 0.1x" range. So I convinced myself that I still know how to shoot

I will try H1000 next as I know I have some.

I havent tryed the Hammer yet but one of my 338 Rums like the 285 Eldm's .

Some take a little longer to break in, my old .375 is the only one that shot brand new.

Good to have a reliable confidence builder in the safe! That friskier recoil, may prefer a little different hold, not talking flinch, just a small change in cheek weld, or follow through a little longer. Something small.

My other one like the 300 Bergers . These are both with H-1000 powder too .

h1000 ci 250 and what ive seen these bullets love speed .. you should see 3200 pretty darn easy with this combo! I shoot a ton of 338 rums with 225 accubonds and a stiff charge of h1000 and don't be afraid to seat them out .010" off the lands to start
