annealing question

[potatoe]

I have a dasher I use for varmints but I'm using a warm load. I'm only getting around 7 firings out of the bras. According to quick load I'm running about 66k psi.

I'm thinking that an annealing machine would help me get 10+ firings but I've never annealed before. Any input would be appreciated.

Are necks cracking or primer pockets getting loose first?

No both of them are good. I've noticed though that once the bras starts clicking in the chamber my groups double in size. I'm thinking it's getting too hard. But am open to suggestions

Tony Boyers book covers this problem. Lowest shipping Midway USA. Hot loads. I think it may be related to the case side walls sticking to the chamber. Annealing doesn't help. Why do you think you have to shoot hot loads to have an effective varmint rifle?

I have his book but its at my old house and want to re-read that part. I remember that part a little. I knew this load was little warm but thought I could get a few more firings out of it. I will drop the charge to the next node but if I could get away with 80gr. Nos. BT's @ 3560 fps I was going to try everyway I could to keep it.

I am not an expert on dashers. I shoot light bullets. Have you tried 8208 and H322 for velocity?

I tried N135 but got a sticky bolt before I got up there in velocity.
