N120

Are there any other signs of high pressures? If not, I'd go for a change of primer.

If that doesn't sort it I'd have the headspace and firing-pin checked

Doesn't sound like too much of a problem. I get craters around the firing pin with highish loads in my Sako.

Shouldn't be more than a thou, and max' 0.003" I think? I'm puzzled if the harder primers are still resulting in cratering though, especially with the load you're using You may need to have the bolt face bushed to reduce the aperture size? What's the profile of your firing-pin tip like? Is it rounded, or is it more sharp-edged? If so, perhaps deburring it will prevent too much weakening of the primer?

Thanks it very slight not noticed when I used reloader 15.I only change powder due used up reloaded and mates said give Bit,local shop rec the 120. I have only loaded 40 rounds and can't afford not to use it up .

It would be interesting to see a picture.

I wouldn't worry about using N120 - as long as your reloads are within pressure limits. It fills the case less but provides more reloads per tub .

Thanks for the feed backs received.I have a laptop being set up within the next couple of weeks,the tablet I am using keeps cutting out on me ,and reading what I have entered seems to change when sent.Please bear with me , but it will make a great target in a couple of weeks.A mate has just called in he uses a 223 with n133 and has the same marks on his primers.I have sent an email to Vihtavuori asking for their views and will keep you updated thank you again .
