Anyone use coated led projectiles to reload for this rifle. Experiencing horrible leading using 240g coated E. KEITH SWC from Missouri Bullet Company. I've used coated lead bullets from MBC in 9mm, 40, 10mm, and 45 ACP for years and have never experienced leading of any kind.
I contacted MBC and was told that Henry micro grooves some of their barrels. He said if that's the case I need to go up in diameter from a .430 to a .431 or possibly even a .432 diameter projectile. Anyone ever heard of such a thing? I will say that when looking down the barrel there appear to be more lands and grooves than normally found in a regular barrel. Not sure why that would have any effect on the actual bore size of the barrel itself. He wants me to slug my barrel and get back to him. I don't have any way to slug the barrel and I'm not crazy about beating a lead swc all the way through a 20" barrel so that's not happening.
Any thoughts or ideas on this would be greatly appreciated. Thanks.
Not sure if this belongs in the reloading section or not. I put it here because my main question is about micro groove rifling of the barrel and bore diameter for this specific firearm. Mods please move it if needed.
