cdnwalleyeWell I tried the marking a round with a felt pen and reincerting it at different possitions and no luck. I took abit of material off of the shell holder and then f/L resized and they would go but it looks and feels like it pushed the shoulder too far and gave them a lip that you can feel with your finger.(not smooth) I then took another bunch of once fired factory brass and just neck sized them and about 50% would chamber and allow the bolt to close with ease and the other 50% were still tight.
Does any of this make sence? I am loading 25 brand new never been fired brass tonight that chamber like a dream. I will fire a few on the weekend and see how they react.
The fella that runs the place i bought it from told me that the short and supershort win mags have very tight chambers and are tough to load for. I told him that i was sure they had tight tolorances but there are thousands of guys loading them and not all are having the problems i am. I kinda dont think he wants the hasstle of sending it back to winchester to get checked out. I sure dont want to as specialy in the middle of the most awesome time of the year for yodel dogs. Any and all help welcome.
Thanks

irwinNew set of dies? Just for giggles, take the expander/decapper out of your die and size a couple cases. It seems pretty weird that you got a 50/50 mix of good/bad brass after necksizing only. Using enough lube in the neck to keep the expander from pulling the brass?
What brand of dies are you using? Everything tight on your press; die insert, linkage, nuts and bolts? What brand and model of press?

<eldeguello>Like I said, if a once-fired case will not easily rechamber in the chamber it was fired in,
BEFORE ANY DIE TOUCHES IT, < !--color--> something is wrong. Even an '06 case fired in my M1 goes back in and allows the bolt to lock. What you are experiencing is WEIRD, if the chamber is not out-of-round. And your felt-tip pen experiment seems to indicate that that is not the problem. Taking the expander stem out of the die won't help, because it is obviously NOT the sizing operation that's causing this!!
I'd have to have a chance to examine your rifle and some unresized, once-fired brass to even maybe get a clue as to what the problem is. This is not a simple problem that can be diagnosed by remote control, obviously! Mere factory load level pressures should not cause this. When the .264 Win. Mag. first came out, some of the factory loads were sop hot they caused pierced primers, but the cases all went back into the chamber.
Do you have a reliable, highly experienced riflesmith or long-time reloader close by? If so, consult him!!

What this guy told you is of absolutely NO value in solving your problem! NO centerfire cartridge is any harder to reload for than any other, except perhaps those in the .30/30 family that have thin brass which is susceptible to collapsing if it is massaged too vigorously!
