I recommend you make sure you are at least .030 off the lands. That should take care of any variables.
Using the OAL shown in a loading manual may not be safe in your rifle.
The Hodgdon Annual Manual shows loads for Nosler 160 grain Partitions in the 7mm RM at 3.290 which was too long...
Aggie Dog:
You’re probably right. I’m sure the real Californians aren’t anti-gun, and most of the transplants are. We have the same crowd influencing the Greatland. Many of which came up from CA, some by the way of Seattle, and God only knows where else.

That’s a good point, but...

High primers are a potential danger because they can go off when the round is chambered.
I used to have trouble getting my primers seated deep enough until I started using one of the Sinclair Primer Pocket Uniformers. Now, I don't need to check with a straight edge, I can feel them...
Savage Fanatic:
Those cases look perfectly NORMAL to me.
The case expands when it is fired, but it cannot expand the web of the case which isn't, for lack of a better term, "hollow". Except for the primer hole, it's pretty much solid. The ring, shows you the dividing line between where it...
Probleee, yotesmoker and Steve4102 got it pegged, but always pay close attention to what Brian described.
If the crimping step is touching the case when you don’t want it to, it will start to collapse the neck spreading the shoulder. I’ve had to redo handloads done by someone else that had...
The classic cause of protruding primers after firing is LOW pressure.
On firing the case normally is knocked forward by the firing pin, and when the powder ignites the sides of the case stick to the sides of the chamber. The case then stretches backwards and flattens the primer.
If the...
I brush the inside of the necks with a brass brush, and clean only the outside of the necks, usually with steel wool. I deburr the primer holes the first time, and uniform the primer pockets, trim the length, and chamfer, and clean off all the lube after sizing, but I see no value in a case...
I clean only the necks of my cases. I don't even own, or want to own a Tumbler. I've used a number of methods, like steel wool, or tiny bit of Water soluble Brass Cleaner or even Brasso on a rag, and wipe the case neck with it.
I always wipe it off real good, and I've never had, or ever...
Granted, changing seating depth will effect the pressure curve, so in some circumstances one seating depth might work better than another. IMO, there is nothing wrong with attempting to tune a load with different seating depths, if you wanna. It might work for you. I do other things, myself...
