I'm not much for shooting unless I'm shooting at meat, but nothing quite satisfies like a custom anything. It's yours and only yours ! A couple years ago I had a .280 Rem built by Alamo Precision here in Texas. Like you said, it's great and I'm decent. About as far as I'll ever shoot in the places I hunt is 250/300 yards, but it's satisfying to know I could stretch that if I had to. I did have fun working up a load with the bullet I wanted to shoot.
Good looking rifle there BTW !
