Hi all. I'm looking at starting to load for both of these and was looking at some hard cast projectiles. They are listed as .429 dia, will they shoot ok out of my micro grooved Marlins? I have read a fair bit about people saying I need to get .431-.432 but these sizes are proving hard to get in Australia. Any thoughts.....
Yeah, that's said and in theory it has merit. But with all the other factors the only way to really find out is to try'm. I'm not having any problem with Cast Performance sized .430 out of my 444's. And Oregon Trail "Laser Cast" .431 from my 94. There's also other mail order casters like http://www.beartoothbullets.com/index.htm that will cast'em bigger by request. But if you list what your shooting them out of they'll know how fat to make'em. First time I ordered from Beartooth I chose the .430 size because that's what I was shooting in the CP's. They saw what I'm using and called me to suggest I should try .432 in my Marlins. They were right.
