[QUOTE="VinceMule, post: 3034695, member: 122164"] I would suggest that you get a RCBS small base sizer for your 7 STW brass. Brass is too large for the chamber. Mic the various brands of NEW brass just in front of the belt, get ready for a shock in how much they vary. As reamers wear, they cut smaller chambers, plus reamer makers have a +/- 0.0005 tolerance in the reamer grind. When there is only a .002 difference between the New brass dimension and the web dimension that the reamer cuts, you will end up with difficult extraction and production dies can be all over the map in spec due to reamer variances and heat treatment that may allow out-of-spec. Some brands of STW brass is pure junk, soft where if you try and push the pressures, you get hard extraction, case head swipes, and enlarged primer pockets in a hurry. I ended up with Winchster 7 STW brass and was very happy with it. If you can ever find any PMC 300 Weatherby and form it to 7 STW, you will have the finest 7 STW brass on the market. [/QUOTE]
