What grain for .300 Win
 

Hey everyone. I recently took my new Rem 700 300 Win mag 26" SS barrel with the Burris E1 4.5-14X42 scope on it with 150 grain Winchester XP and I cant seem to get a good solid grouping to work with up breaking it in at 200 yards. I'm thinking that the 150 grain bullet/quality ammo I'm using might be my issue and was hoping to get some suggestions from any other .300 Win mag guys on the ammo they are using and what grain of bullet seems to be the best for good accurate groupings.. Any additional suggestions are appreciated.

What are you going to be hunting with it? I'd recommend you use the same exact load you're going to be hunting with. I can't answer that question with certainty as all rifles shoot different, even among the same make/model/cartridge. I do know that the 5 different 300 win mags I've owned all "liked" 180 gr loads regardless of brand/model, and most really shot anything 168 gr and above excellent.

I like 180 grainers also. And the BC of a .308" 180 grain BTSP bullet is pretty darn good.

I'll be deer hunting with it in Nov, but also plan on large game hunting. Elk..Moose, ect. I figured 180 grain was going to be the most popular grain, but I really wanted to some insight on it from here. Any specific brand of ammo recommendations? I was looking at Winchester silver tip and federal. Seems like a lot of people are saying that shoots pretty well..but I guess the barrel likes to pick the brand of bullet sometimes.

I'd experiment around with different brands/types/grains but if it "likes" Nosler Accubonds GREAT! I don't know much about modern centerfire loadings as I use all ammo I've loaded myself only for about 35 years now or possibly even longer.

Like said depends what you plan on using it for.
I use mine for long distance (300yds or better) white tail across cranberry bogs. I hand load a 165gr Sierra HPBT game king bullet for this.
I would not hesitate to use the same load on elk or moose.

:D Al

I'd think Game Kings would open up too quick for elk or moose. I used to use the Game Kings on deer and they seldom if ever exited so a elk or moose needs a lot more penetration than what's ideal for deer, unless you use your elk load on deer.

Try 165 gr., guns are like women one shot, she do'nt like you- now you go to then next one.

I agree with all of Stalkingbear's posts - especially about Sierras.

Re. 180-grain Accubonds, they fly great out of my M70 and have put some nice critters in the freezer, but my bull elk experience last week makes me think they might be a tad fragile. (Of course, the elk's dead, so maybe I'm overthinking it.)

Dang BTM that's a great compliment! Thank you! I didn't know anybody paid any attention to my posts lol! I've had great results with 180 Accubonds out of a 300 win mag. From 50 yards to 419 yards they perform perfectly!
