anyone ever build or shoot a 7 wsm with a 22 inch barrel? this is going to be a hunting rifle so i will be shooting 160 accubonds. any short barrel info would be great.

Re: 22 inch 7mm wsm velocity

I had a custom built from a Winchester M70 action. My want was a light weight hunting rifle. I had wanted a 22" barrel and the smith recommended no shorter than 24" to get the best performance for the 7mm WSM. Don't remember all the specs though. Lilja barrel with an MPI stock. Final weight was just over 6lbs. I wanted to use 160 Accubonds but never shot well with RL19, RL22 or IMR7828. Then RL17 came out and out of frustration I tried 154gr Hornady Interbonds. Stuck with that combination. I get 2970fps with 58.5grs of RL17
