Re: 7mm RUM reloading difficulties
Just to let everyone know, we found out the problem. Thanks for all your input!
Seems as though, when trying to press the bullet into the brass, the bullet was hitting the edge of the die, more than the peice that you screw in from the top of the die.
This was causing it to go in partially crooked I think and warp the brass. Instead of the shoulder being staight, it ended up looking bowed more.
So with different brass and loading the bullet correctly, we fixed that problem.
Also, after I realized that the rounds we loaded the first time were not going to work...we tried to unload them. We have a hammer for this usually, but due to the extreme size of the round, it wasn't working, so plyers had to be used.
The teeth in the plyers ended up indenting the bullet, and ended up also causing trouble when locking down the bolt. However, after filing some on the bullet to "de burr" it, the new round goes in great.
As of now Im using an overall length of 3.7" with 104.5 grains of BFG50 Powder. Hollow point 140 grain bullet. [img]/ubbthreads/images/graemlins/cool.gif[/img]
