    I'm completely new to reloading so I thought I'd ask those of you who know what you are doing for some insight. I got a Lee classic loader so I have that. Now I'm trying to figure out what bullet and powder to use. The rifle I'm planning to load for is a Thompson Center Compass chambered in 270 win. It has 1:10 twist, 22 inch barrel, 5r rifling. I put a vg6 gamma precision muzzle brake on it too. The pic is before the brake. IMG_20180731_173118846.jpg

    bc probably doesn't matter as much since where I hunt I can't shoot past maybe 400 yrds. I prefer a somewhat light bullet at a fast speed but not so light that I don't get exit. An exit is important to me because I don't do shoulder shots because of meat damage. I go for heart/lung or if within 100 yrds I go for a neck shot just beneath the head. I do like a bullet with nice expansion into a beautiful mushroom. I'm not really into fragmenting stuff. A few fragments is ok I guess but prefer not.

    Nice looking rifle. Whatcha plan on doing with the rifle? Hunting, putting holes in paper?. Most won't argue that the 130gn bullet and H-4831 is the way to go for the 270. My favorite caliber btw.

    What will you be hunting, deer, elk?
    130 grain for deer
    150 grain for heavier game
    60 grains of h4831 sc on 130
    60 grains of Rl 26 with the 150

    60Gns is on the high side for 4831. Please work up to that carefully.

    Is the 4831 temp stable and fast?

    I've never noticed a problem. Very hot climates i would back off a grain or 2.
    60 is the recommend max in most reloading manuals.
    Should be somewhere in velocity between 3050 to 3100

    Thanks, is there a powder that is faster but still temp stable from -20° to 100° F.

    Reloader 23 is noted as a temp stable powder.
    As far as primers i use cci. There will be others weigh in so you probably will hear of several favorites. I have had more remington to snap, than any other brand. If you use your gun in cold weather, maybe you might want a magnum primer.
    Btw remington is the only ones i have ever had to snap

    Alliant's website shows data for the 150 grain bullet only. But it should be ok for 130 with a slight increase in powder charge. One thing i can't stress enough, get you a good reloading manual. Read it and you will learn a lot before ever loading.

    Hammer Hunter 117
    H4350 @ 59.0 grains
    F210M primers

    3300fps
    0.786 inches at 200 (!) yards from a factory rifle.

    Deadly on antelope, with pass throughs and 1-shot kills every time.

    Work up to this load, as it was getting near the max in this rifle, and I use a chronograph to watch it.

    In my experience, almost anything you load in a Hammer will shoot better than you can. I tested 3 powders and this one worked the best for me.
