375 H&H Mag 250 gr SMK

[JD338]

When I started the 375 H&H Mag adventure, I wanted to try the Sierra 250 gr Game King bullet but they were unavailable. Fotis mentioned to me he was about to use this bullet a couple weeks ago so I got a couple boxes.
I loaded up 4 rounds with CFE223, a load that I had used with the 250 gr TTSX. Went out to the barn and shot 3 at 100 yds. The Garmin Xero recorded and average speed of 2894.6 fps and the group measured .625". I put the 4 bullet into the jugs. Recovered in #5 but dented jug #6. The recovered bullet weights 204.5 he's and measured .790". I think I have a load for deer!
I loaded up 3 more and took a walk out back late that same afternoon. Shot a big doe at 50 yards and the impact knocked her right off her feet!
Not to shabby for a load development job, completed in one day with 5 shots.
I will play around with it a little more just because.

Very good, Jim. Yes, I do believe you have an excellent load that'll work for far more than deer. But it does unquestionably work for deer.

Damn, that looks like an excellent combo and that bullet held together surprisingly well for that speed. Nice job. What are you shooting it out of?

 

[NYDAN]

Very nice, Jim. Congratulations. Looks like a great combination.

Very nice Jim, you getting the big bore fever for whitetails like Rick. At least you not using the 460 Bee with a 500 grain bullet like he does. Big thumper for sure at 2900 fps.

I shot that same bullet for quite a few years in my 375-358STA. Mine was running 3080fps in a 27" tube with 4350. It hammered all kinds of animals from a duiker to a kudu in Africa and antelope to elk here.

 

[JD338]

Thanks fellas. I'm very happy with the results.
The rifle is a Nosler M21 topped off with a Leupold VX-5HD 2-10x42mm with fire dot reticle and a CDS dial. I've shot it out to 600 yards. Hopefully it will make a trip to AK and Africa.

You made quick work out of the load development and test media, both jugs and deer. No doubts about this one.
Dan.

 

[RL338]

A very quick and rewarding development Jim.

 

[Hunter26]

Sweet rifle, would love to get an M21 eventually. Did you mean 2-12? Or is it a VX-5?

My bad. It's a VX-5HD 2-10x42mm

Dan,
The amazing part of it is it was all done in one afternoon! The stars must have been aligned just right.

4 loads for development and then a deer with the 5th. That's a great use of components and they will last a long time that way! That 250 gr Sierra looks really good, the 225 gr 358 performs very similar.

 

[salmonchaser]

Excellent, gotta love the 375HH

 

[truck driver]

Very nice JD, you have to love the medium bore calibers, 358 and up, they just simply work on whatever you shoot with them and surprisingly very accurate also.

 

[Guy Miner]

OUTSTANDING!

I've never tried that bullet from the 375... Hmmm... That's a LOT of velocity too.

Congrats on your great results.

Regards, Guy

Take a look at this bullet being tested out of a 378 Weatherby. The results are impressive.

Nice work Jim. Man, that bullet came out looking great.

The 225 version is awesome in the Whelens so I always wondered how good the 250 375 worked.

 

[FOTIS]

The 300gr SGK is exactly like this one . Very tough. Got it through my 378 and what newsprint at 40 yd at 3,050 ft per second and it looks exactly like this

 

[FOTIS]

Jim. What your COAL with the 250 Sierras
