Home Forums Reloading Big Game Rifles .444 Marlin resizing effort

Fairly new to reloading (I've loaded maybe 1500 .223 and a couple hundred .45 acp) and just started reloading for my .444 Marlin, bought a bag of Starline brass which appears to be beautiful stuff. Loaded some rounds with H335 and 300XTP Hornady's at 3 powder levels working my way up (still about 3 grains under the Hornady manual max). Very accurate loads, the last group with 49 grains was a very good load. It seems to have plenty of power (on both ends).
Anyway my question is now that I go to reload the now once fired brass using RCBS dies it seems to take quite a bit more force than I'm used to with the .223. I'm thinking that two things that might be possible are that I didn't use enough lube (using Lee resizing lube from tube) and that the resizing die probably resizes the brass a little more due to the fact that the caliber is mostly a lever action caliber - almost a small base die set if you will.

Hard to judge the force I know it just surprised me.

Thoughts?

Lot more brass on a 444 than a 223. That
Might be the rest of the story

Try some Imperial Sizing wax.. Works great on my 45-70 and everything else that needs to be lubed.

If you find that the extra lub doesn`t ease the sizing, your chamber may be a bit large. In spec, but a bit large. Try sizing a case maybe 2/3 of the way down, then pull it out of the die. Wipe off the lube, and you will see that where the die stoped a little bulge in the case. That bulge is how much brass your moving back in place in the sizing process. Therefore the force needed by you to do so.
Also, most straight walled cases don`t have a lot of taper to them, unlike most bottle neck cases,.223, so sizing can start right now.

Let the lube on the brass soak into it over night.. then seem to work on my 444 that I have had since 1981.....
I use Amzoil gun lube for lubing brass....
