I finally broke down and bought a set of Lee dies for the new Ruger M77 .350 Rem Mag I've had in the safe for the last few years. I'll probably pick up 100 Remington cases and 100 Hornady 200 grain Interlocks for starters. I think I'm going to put a Nikon Monarch 4x40 I have handy inside those awesome Ruger integral rings. I'll be looking for a heavier load in the future as well. I'd love to hear what bullets, powders, and performance folks are getting with this round. I suspect some .35 Whelen data you all have could be applicable too. Thx!

My Ruger M77 350 Rem Mag likes Sierra 225 GK with 748, with a muzzle vel. of 2600. You do not need a premium bullet with the 350. I tried H 380 and IMR 4320 and a few 200 gr bullets to find what my rifle liked. Use loads from a reliable source like reloading maniuals. The internet is not a reliable source. I love the 350, I am sure you will too.

Bird Dog II,

Happily, I have obtained many NEW rifles in my long life. Have you read any current reloading manuals regarding your .350? If not, I suggest you do so and read them cover-to-cover. Then, begin at the STARTING Load and LET your rifle "Tell" you WHAT loads to pursue for YOUR rifle.

Internet reloading data is NOT a shortcut to proper load development for YOUR rifle. Good Shooting.

Nosler's newest reloading manual has a good article on that caliber. I also remember reading interesting information in Hornady's reloading manual also. Both are very good books and ton's of information for pennies a page.

I had a M600 for a while, and just never fell in love with the bolt, and the short barrel was a bit of a handicap. The 225gr Sierra was a great bullet, and I used BL-C2 to get them going, close to 40 years ago. I'd still give that a try.

These days I have a pair of Whelen's, a tall .350 Magnum without a belt. The single advantage is it holds the longer bullets without eating half the case room. The 225gr Sierra is a favorite for elk, and I've bumped a couple bulls off with that, over my special reserve of RL12. RL15 is just as good. BL-C2 is a runner up along with W748. With a 24" barrel I get 2700fps, and it shoots with a good .243 as accuracy goes. My 7600 uses a bit less powder, and the 22" barrel drops speeds to the 2600fps level.

The 250gr bullets work fine also, and you can get some pretty good velocity from those in a 22" barrel. The same powders work about the same for those. For close shots at large game, the RN might be just the ticket.

An older Speer manual recommended Reloader 7 with 125 gr Sierra pistol bullets to have fun vaporizing "things". I can tell you until you've witnessed the devastation this load does, you have no idea. I mean, nothing can compare.
