Happy with .375 H&H load results

[Longwalker]

It's so satisfying when a series of loads all play nice together! I've been developing loads for my Sako .375 H&H. This is a couple test targets from today, shot at 100 Meters.
Left target is 300 gr. Hornady round nose soft point propelled by RL 15 at 2510 FPS. A nice, accurate full power load for anything smaller than buffalo.
The right target shows three shots from a Remington 270 gr. round nose factory load which I measured with my chronograph at 2670 FPS, then four shots from a mild practise load (or hunting load equivalent to a 9.3x62). It's made with 60 gr. of IMR 3031 and a Hornady 270 RN bullet. Velocity is 2350 fps. Recoil is mild. The two 270 grain bullets show the same point of impact, and both hit just a bit higher than the 300 gr. load.
I suspect the Remington ammunition is actually loaded with Hornady bullets, they look identical. But I didn't expect that they would shoot to the same impact point with such different velocities. Sometimes its nice to get lucky!

Always nice to get lucky.

Nice load development. I also use RL15 in my 375 H&H using Barnes 309 gr TSX. If I do my part my rifle will cloverleaf 3 rounds at 100 yards.

You’re lucky! Sometimes it’s is not as easy. For example, my BRNO ZKK 602 shoots all over the paper with the Hornady 270 grains SP. I tried 3 or 4 powders and the best I got was 3-4 inches groups. I finally gave up with this bullet.

I also use Re 15 in the 375 HH but behind Nosler part.

CFE223 works very well in the 375 H&H behind 270 grain bullets, which are what shoot

@jwp475
CFE223 certainly is versatile.
17 Remington to 375H&H so far.

I may have to try CFE223 in the .375. The .222 REM loves it, varmints do not!

I use rl 15 with a 300 gr tsx at 2,610. Cloverleafs em out of my Dakota

 

[Luvthunt]

Re 15 and IMR 4350 bout covers all needs

How long is that barrel?

 

[jnmullins]

I use RL15 behind 300gr TSXs also. They shoot very well and they performed very well on everything I shot in South Africa this spring.

I have loaded and tested some white tailed deer loads in my R8 375 H&H.

13.0 grains of Red Dot behind a 270 grain powder coated cast wheel weight lead bullet. #375449.

1" at 100 yds. No filler. Running at about 1300 fps. Right at 38-55 power. Sweet shooting.
