30-378 Weatherby load advice

cmfi3 · #1 02-29-2008, 11:02 PM

Going to start loading for the 30-378 weatherby accumark. Looking for suggestions from those who have experience loading for this cartridge and rifle. Thinking about 200 gr. AB and/or 180 gr. TSX. Looking for some ideas for a "hunting" round out to 700 yds and any loading suggestions for this caliber. Thanks

I've tried H1000, H4831SC, H50BMG, & RL22 with 180 accubonds and 200 SMKs. The best load I have so far from my accumark has been 117 grains of H50BMG with a 200 grain SMK. WMLR primer. OAL of 3.645". I was able to get a .345" group from 100 yards. I still have a lot more testing to do at 200 yards for accuracy. I also plan to try some 220 and 240 grain SMK's when I can get my hands on some.

Used the 200 SMK load last year to take a bull elk from over 600 yards. One shot, quick kill. Personally I wouldn't shoot less than 200 grain bullets for LR purposes.

Here's an excellent place to look around. Work up to some of the max loads as they might be warm with certain bullets/guns.

thanks for the info guys, im thinking I may start with 200 gr. AB with some H50BMG as soon as I can get my hands on some. Desertdiesel, what kind of velocity are you getting out of your 200 gr SMK/H50BMG?

It was in the ball park of 3200 at the muzzle...

Heck, My RUM does 3200 fps with a 200 gr bullet. With 92 gr of powder. mtmuley

I hear you Mtmuley...I plan to try some 220 and 240's. I read where guys are getting the same velocity (3200 range) with 220 grain bullets.
