Hey Guys, Got a interesting problem going on...Ive reloaded for years and am usually pretty ontop of problems..this one has me stumped....Ok Reloading for a buddys 300 Weatherby...having problem with brass going back in sizing die after it is fired thru this gun....brand new brass goes in and sizes easy...they close nice in the gun...shoot them and they are stuck, have to pound them out....Go to resize...case wont go all the way in. Die...Tried Rem brass and Weatherby brass...even took factory brass, once fired...went in die fine... loaded it shoot it same thing.. its like after shooting thru gun they are expanding too much where the case will only go half way thru die before coming tight..Knowing stuck bolt is signs of pressure...knocked the load way down...3 grains under max....same thing...changed powder and same thing.....is this a chamber problem and extractor problem or am I missing something...Ive loaded this same load for this gun a few hundred rounds No problems....Thanks Guys
