Loading over max powder charge

[onelastshot]

I don’t know how temp sensitive that powder is but if it’s only 19 degrees I’d be real careful loading anything close to a sticky bolt. I loaded some rl17 in a 284 and was getting great groups and no pressure signs around 65 degrees. Fired a couple at 95 degrees and the second one blew the primer straight out of the brass and the bolt was very hard to open. This was just slightly above max.

RL17 is known to be tempture sensitive. My loads change in the summertime.

Loading over max powder charge?

if you are asking that question then you probably shouldn't

41.9: Chrono didnt pick the velocity up but the bolt was sticky so i stopped there

No velocity increase for an increment increase in powder is a good indication that you should check your health insurance before proceeding further.
