Surgeon 591 test load

[BlackWhiskey]

Had a few hours to get out to the range today and test a new load. I was only getting 2660fps so I'm thinking I may want try to bump up to the next node.

Re: Surgeon 591 test load

Good Shooting!! I am looking at a similar set up but with a different action of course. I would think you could bump up the powder a little more. I am wondering what speeds people are getting with the 140's and barrels shorter than 26 inches.
