deserthntr Report post Posted September 13, 2010 reloading question. so i reloaded some ammo and shot it, found a decent load, and was going from there. well today i was working up some more and when i had seated the bullet it wouldnt fit in the gun. it would go until i could almost close the bolt. so i could push it far enough in until it was time to push the bolt down. nothing changed since i had last reloaded, except i noticed some of the brass were 300 mag, not 300 win mag. idk if there is a difference but i would resize and everything would fit good, but everytime i seated the bullet it would no longer fit in the gun well enough to close the bolt. so could seating a bullet on a 300 magnum not a 300 win mag mess up my die? and i would check if the brass would fit before seating the bullet, everything was fine, seat the bullet-not work-, then take the bullet out the brass and it still wouldnt work. i was doing this with just 300 win mag brass after i noticed some was 300 mag. but could anyone help me out? and maybe someone who does a lot of reloading could come and help me make sure my dies are set up correctly? thanks i appreciate any info/help. oh and i am in mesa Share this post Link to post Share on other sites
azgutpile Report post Posted September 13, 2010 This is just a guess, but it sounds like you might have the seating die set to deep, which can crush the case and cause it to bulge right below the shoulder. What kind of dies are you using? Share this post Link to post Share on other sites
jeffro Report post Posted September 13, 2010 To start all your brass should be the same brand and head stamp. If you can all the same lot is great. Was the brass shot out of different guns. If so the chambers of two different guns are not the same size. If you are not FL sizing your brass this could cause a problem. If you want to FL size screw the die down until the bottom hits your SH. This will cause more wear and tear on your brass, but if some are fitting, and other are not this should help.

jeffro Report post Posted September 13, 2010 When you use brass with different head stamps you can run into many issues. The case volumes can be quite different. Neck tension can be very different. On and On. This will cause problems with ES SD and preasures. It all depends on what you want to get out of the rifle I guess. Share this post Link to post Share on other sites
deserthntr Report post Posted September 13, 2010 i figured it out, and i had my die set too deep, i was making it so i ran it past the belt on the bullet, and i guess it was doing something. got it so i wasnt doing that and everything is working out perfect! thanks for the input!
