I just got a used ( its new to me) 375 Ruger Alaskan. I have some 270 hornady bullets. I eventually want to shoot 260 nosler accubonds but for initial getting it on paper and trying it out I am using the cheaper 270g
I have r15, imr 4350, and 4831.
I am looking for a middle of the road maybe 2500-2600 fps load that is accurate. Any recommended loads to start with?
Also, anybody use 375 h&h load data since the case capacity is so close?

Hodgdon website has data.

I have read tons on how using RL15 is the gold standard in the .375, but that's the H&H. Not sure about the Ruger. Tagged to see what works for you!

Re 15 is all you will ever need for a Ruger .375. I've had one for about five years, and have tried some others, but they really don't come close.

I'm shooting a 270 gr load at about 2600 fps, which are about 250 fps down from the top -- but then who really cares...

I use IMR 4350 for practice and Marmot/P-dog use. 81-82 gr and the Hornady 270 SP gives just over 2700 in my Alaskan.

For 270 TSX bullets I use the max listed of RL-15 and get almost exactly the same speed but the POI changes a little. Both loads are varmint rifle accurate with only a 1.5-5 VX-III. I've shot the Hornady out to 400 yds. on steel with great results.

Dennis,

Out of sheer curiosity, at 2600 fps do you find a noticeable decrease in perceived recoil?

Would you mind sharing the load?

I am thinking of 70g R15 and 72g imr4350. Any idea where that would put me?

Some, but no big deal. It still has plenty of action...!

Dennis

I load 72 gr on mine, at 23". The bullets are running just at 2650 fps, and shoot just under an inch. I know I can shoot heavier loads, but don't know of any reason to do so.

Dennis

72g r15 sounds good. That is one of the few loads I have been able to find on the net. I have checked a lot of sights and found either bullets I have listed with different powder or powder I have listed with different bullet weights. I would also be interested in any loads using imr 4064 or 4895.

I've used RL15 for my 375 Ruger reloads, with good success- but prefer the results I get with Big Game powder. I mostly load the Barnes 270 TSX, with MV around 2800 fps, which gives very accurate results.

Are Hornady 270 spire points Interbonds or Interlocks?

Hard to beat a maximum charge of 81.5 - 82.0 gr Ramshot Big Game and a 270 grain Barnes TSX for 2700 fps out of the 20" barrel of my Ruger Alaskan.

I,ll 2nd that load!

Interlocks...

76 gr of imr 4831 with that bullet in my H&H is submoa
