Went out yesterday with my .300 winny to chronograph my load with 215 Hybrids. In my last barrel I was getting 2,930 fps with the same load. I'm getting 2,885 fps with an ES of 12 in my new barrel. I went with a 1-9" twist in my new barrel as opposed to the 1-10" twist in my last barrel. Both were 28" Hart's.
I'll take a small hit in velocity for the kind of accuracy I've been getting out of my new barrel. Here's a picture of the typical types of groups it has been shooting.
