I pushed it into bore by thumb pressure, there was some resistance with rod on way down barell, but not much.
Sounds like you've got a perfect fit. The ramrod on my 3 band will push a minie all the way down till the last three inches or so by itself. With well lubed minies it will do it first shot or 50th. You've got to keep the temp up and the mold hot to cast those big minies. I have to reheat my Lyman every few minutes to keep it hot enough to cast without wrinkles. The Lee isn't so bad. You don't want hard lead at all. The stick on wheel weights are perfect tho, just leave the clip on ones for cartridge bullets.
