375 Ruger reloading info

Don't overlook the Hornady 270gr SP for range blasting and hunting as well. I'd use them in my 375, but it likes the 260gr Nosler ABs better.

I started a load work up, starting at 79gr of H4350 and going to 83.5gr

(Top left group)

Next I wanted a practice load, so I chose the 270gr Hornady Interlock Working up from 78gr H 4350 to 82.5, the group was opening up at 82.5 and so I backed down and took another shot with 81gr, which cut the first 81gr bullet hole, so I figured I was close enough there, too.

I briefly thought about dicking around with it for better accuracy, but decided against it. All I am going to do with that load is shoot milk jugs and bang 8" gongs from 25 yards out to 400 yards with it, I don't care if they all land in the same hole.:)

I tried out the 260gr Accubond load that had shot so well when the Hogue Stock was installed, and it did pretty much a repeat performance of the original groups:

Good to see H4350 working so well for you, Gatehouse. Hope it works similarly in my 375Ruger. Keeps the powder cabinet stocking very simple when a guy can get by with HVarget and H4350.......:)
 
In attempting to get the velocity with we wanted (2700 fps) from 260 gr ABs in my pal's .375 Ruger Alaskan, I didn't have much success with H-4350 and Winchester 760 was equally disappointing producing a velocity of 2600 before high pressure was observed. We then tried Re-19 and 90 grs broke 2800 fps, but required a drop tube which I have little patience for. The 89 grs load made the target velocity all right, but still required a drop tube. Finally I ordered some Hybrid 100V and liked it so much it has become my go to powder, not only in the Ruger, but also for my .375 Ultra and the .30/06. We settled on 86.0 grs of Hybrid 100V which drove the 260 gr AB at 2734 (5 degrees C, at sea level) and it did not require a drop tube to charge the cases. Accuracy was .75 MOA for 3 shots from prone.

Just goes to show that every rifle is an individual...H 4350 gave me better than expected velocities, with no pressure issues.
