I was thinking 53gr and work up to 55gr but am I being conservative ?

Talk to Alpy mate, he's working one up right now. I'd be looking at 2217 in the 6.5 variant though.

My load for the 156 eol bergers is between 55 and 57 gr of 2217 i found that hornady 140 147 and 153 all were blowing up at speeds of above 2980 fps.
Hope that is of some use.

Sorry forgot the barrel is 1in8

I have my 6.5 prc now so I am going to give it a go ... I just wish I had found some lapua brass, the nosler stuff looks lovely but I dont know how tough it will prove to be ....

Nosler brass is made by Norma

Yes, I know, thats why I am concerned

I can make a few observations from my testing of the tikka UPR 6.5PRC
1. The rifle is very light for a cartridge burning 50+ grains of powder. You would need a muzzle brake for PRS, the creedmore might be a better bet. (I am going to run 2 configurations, a factory stock and an MDT stock to bring the weight up where permissable)
2. It gets HOT , I am going to try 2217 as advised by willow or cut my 2213 load. I have not chronoed it yet but its quick enough.. (3000 is my guess, will find out soon)
3. The brass is holding up better than I expected, but if I ever try another calibre I am going to hoard the lapua brass first like rolls of toilet paper during covid.
4. The tikka trigger was too heavy (2kg) but its easy to adjust and i have fixed that.
5. My next barrel(s) will be 26" rem varmint profile 7.5 twist to try heavy pills, when I can find some

This is NOT from an overloaded case, 2 firings. I also have a couple of neck cracks .... nosler brass. I have sent a box back for refund or replacement at the seller's suggestion..... but I was wondering, would AMP annealing the necks BEFORE firing help ? obviously its not lapua

Is your sizing Die clean and not binding it looks like a Die problem.

good point , although i am not sure what 'binding' means. do you mean i'm pulling the neck up ? Its clean but its an rcbs all in one die,
i have another type of die coming and i'm holding off on using this resizing die on the next batch
but i think the necks are kind of brittle

What die lube are you using?
Pete

imperial, but very sparingly. when i get my redding body die ill stop using the rcbs all in one and do some careful measuring, and i have a forster neck die thats easier on the necks

It may have been like that from the factory

I don't understand the issue with Norma brass. I've found it to be excellent

It's difficult to tell from the photo but that looks like the brass has folded inwards from an accumulation of lube, or is it a split. I would expect the neck to split first
