[QUOTE="243winxb, post: 1340173, member: 97793"] Apply RCBS Lube -2 , using a pad. Lube inside of necks. There have been many post online when spray lube has been the problem. Lube must fully dry before sizing. But cracking 3 FL dies very strange. I would guess the web is expanding from high pressure? Reduce the powder charge after buying new brass. Do not use brass fired in the first rifle. When FL sizing , at the top of the stroke, make sure the shell holder and FL die are in contact. Use a flash light if needed. If the shell holder is in full contact every time and rounds will not chamber, then remove a few thousands from the shell holder. Do not use this shell holder for any other cartridges. The 300 wsm has a working pressure of 65,000 PSI. Very close to when brass will no longer spring back after firing. The web area may never spring back above this pressure. Are the primer pockets tight in the used brass. If pockets become loose within 5 firing, pressure is to high. [/QUOTE]
