I have the parts to build a 22-250 Improved for heavy bullets. I bought a 6.5" twist barrel blank.I am going to build a 22-250 to shoot the heavier bullets and was going to buy a 8 twist for the project. I have a chance on a good deal for a 7 twist barrel to use instead. Am I going to be alright with a 7 twist or should I go ahead and get a 8 twist for the project?
Thanks,
Dan
His was early model Winchester model 70 chambered for theI shoot the 22xc (basically the exact same case capacity). I shoot one of my 8 twists.
It shoots quite well.
What action are you using?
How fast are you running them?7 twist 22-250ai with 70gr RDFs and RL26 has been a great combo for me.
