Thank you very much. That gets me in the ballpark.

I purchased a whidden die set for this caliber. It came with .309-.313 bushings. Using hornady brass I've settled on the .310 bushing but I originally started with the .311.
Thank you Benny. That helped a bunch!

I'm using a Whidden .311 with Hornady brass, do you see a difference with the .310 bushing ?
Good question. I ran a ladder with it after I found a good seating depth and there was nothing wrong with the result.
Topped out about 2975 with a 175 EH.
2984fps. Oops.

I am running 2945 with 175 with great accuracy and low SD. Very happy. Gave up looking for RL 26. VV n568 worked out great

I'm using .312 bushing with whidden dies in my 7 prc with 175 EH and it shoots pretty awesome in the 1-8.4 proof.
I use RL 26 and have enough to wear out probably two or more barrels.

According to Peterson, neck wall thickness is .0142"
Aztec anneal code 0143
pilot #65
H1000 ladder test looks good also, 3024 max, appears it will run between 2970&3005. 175 EH. 24" bartlein

So my experience was I settled on a load using the .311 bushing. I then loaded 6 rounds with the .310, 6 rounds with the .311 and 6 with the .312 bushings. I shot 3 shot groups of the different bushings on 2 different days round robin style. Both days the .310 shot better so that is what I'll be using from now on unless issues come up in the future.
Obviously chambers would affect results. Mine is supposed to be sammi.
I saw a real difference between the OD of 2 different bullets, a nosler and a Berger.
Guess I'll be juggling 2 mandrels depending on my load now

Currently lot to lot variation can be a problem, more than preplandemic in my opinion. It seems the quality control has fallen apart in the rush to supply overpriced components.
One more variable to figure out on OUR time and OUR expense.
While we pay higher prices for the components that cause the issue

RL 25, RL 26, H1000 are all I can find info for......no reference to N's
I've only tried this with n568 but was told by my GS to use 7RM data, capacity is very close.
565-570 should be worth a look I'd think
