[QUOTE="Barrelnut, post: 940533, member: 74902"] Was the day warmer when you noticed the bolt lift issue? They say the powder is temp sensitive, but I have not proven that for myself yet. I ran RL-17 up to 65 gn in my 300 WSM with 180 NBTs, but thought it a tad hot and backed off to 64 gn. Once reason for the backoff was to see how the load performed in warmer weather. It was about 50 deg when I developed it. Also, the Alliant web site list 66 gn as max for a 180 Speer bullet, but that is a SPEER bullet, not a NOSLER AB. The bullets bearing surfaces could be different and that would affect the max load. I would back off to 64 or 65gn and see if it relieves the issue. [/QUOTE]
