[QUOTE="VinceMule, post: 2852963, member: 122164"] NEVER EVER make a bullet seater out of a Finish reamer, you need a die reamer for that as Sherm has stated. Those of us that had this done with a finish reamer, ended up: A. having the die honed out B. using the bullet seater as a full length sizer while seating a bullet C. trashing the die because it was too small There is much wisdom, hard-learned from Sherm's post. For instance, you have a particular brand of brass that measures .469 at the .200 mark on the brass, just in front of the extractor groove. Question: What dia would you make a finish reamer to eliminate premature extraction issues, and again, to eliminate clickers? HINT: 0.001 is nowhere near enough Clearance. Many bullets are oversize, but by how much? [B] What dia would you have the throat dia ground to eliminate pressure spikes from having a throat dia smaller than the bullet dia? [/B] Seat a bullet in your favorite new brand of brass. [B]How much do you add to that dimension to give a good bullet release?[/B] Some of the people you send your thrice-fired brass into do not know their *** from third base on how to design a reamer, better educate yourself or learn the hard way, [B]"an education costs money." If there was a category on Reamer design, it would be awesome as there are many mis matches between particular brands of brass and std reamers, with many gunsmiths not aware of the problems.[/B] [/QUOTE]
