This past season i shot Magnum Blend. I know I should have known this but I didn't think about it. There are different lots of these shells and I know that shell companies change shells. I am going to see William at Sumtoy chokes and get a choke built. I don't know if I should get a local to load me some shells with all the components listed on the box so it can be reporduced if the components are available the next time I need shells. The question is should I go ahead and get some shells loaded and then match a choke to the shells and gun or wait until I need some shells and build a shells to the gun and choke combo.
What kind of gun?? If sumtoy builds the choke for you they will have a better idea than anyone about what shell to shoot.
I would get this years mag blends in quantity enough for two - three years.
Once they make a magic shell they seem to want to screw around with it and it is almost never better. No scientific fact just past experience and scoop from others.
The gun is a SBE
As far as the shells, I order them through a buddy so there is no way to verify lot numers until they get here
