RE: Hornady Light Mags
It is an extreme compressed load. Most rifles don't like them. Especially those with small pencil barrels. It most likely will have sufficent hunting performance. But I would recommend you stay with the standard Hornady stuff.
I tried some 270 long time ago, and got 4" groups from my 7400. I can get 1.5" with handloads. I figured it was just the gun.
So Hornady sent me a new box of 308 due to a friend had trouble with them shooting in his model 7. So I figure why not send them back and then I could evaluate them. I did, and they sent me a new box. So I tried it in three different guns. Two A-Bolts, and a FN APR tactical rifle (that is the best tack driver I ever shot). None would get below 2.5MOA at 100 yards. I wouldn't waste the money.
