Just got a new RCBS lube size in .400 diameter. It will not fit in my Lyman 450 but I have other RCBS sizers that do. It seems to go down to the bevel on the lower end and that is where it stops before entering fully into the 450. Have there been some changes in the new sizers? This one measures .703 just before the bevel on the bottom. My other RCBS sizers (2) measure .698 to .699. My thought is the body of the sizer is to large from the bottom at the bevel to the top near the O ring.
Anyone else have this problem with a new sizer?
I will call RCBS Monday but wanted to find if there is problem I might be overlooking.
