RE: Cast 38-55 gas -checks?
When I wrote my second post I meant to write it with respect. I hope it was taken that way. I also write this reply with complete respect, so please accept it as such.
I have seen some nasty things done to barrels with improper wadding being used. That is why I said I would never consider a metal GC. IMO you are basically adding an additional projectile, and you are putting it inside the case. I avoid any filler's or even wads inside the case. Are they safe?? Yes-but only if applied properly. That is when I brought up beginner reloaders. I would hate to see a beginner "Ring" a perfectly good firearm due to inexperience. That was my only point.
I am sure you know of what you speak.
I have pushed pure lead up to 1650 fps without any leading problems. I do not think you would have any problem at all with 1300 fps. But this is just my opinion. Tom.
