Yea
I'm shooting a 45cal. Meant to say the 275Grain PB. And I'm going back to the range soon and will chrony the loads

I thought you had a 45 cal. from previous posts you have made. Thanks for clearing it up for us. Also thanks for chronying the load. I'mlooking forward to yourreport on that.
Just for grins and giggles it would be interesting to to see how much RS it takes in .50 cal to propel a 338 to the same velocity.
