Re: Contender in 223
I've been shooting the 40 gr Nosler Ballistic Tip. I load Win cases, BR4 primers, and 22.5 grs of IM4-4198, with COL 2.260". This load is a tad over the listed MAX and is fine in my pistol, but you should work up to it from 19 or so. I haven't chronographed the load, but it should be around 2950 FPS.
I read an article a long time ago that indicated only fast burning powders and light bullets shot well in the 10" barrel. If I do my part with the above load, I get sub 1" groups at 100 yards.
If you like your hunting rifle, you can keep your hunting rifle.
