Peregrine bullets seating depth

I’m just about to start reloading Peregrine copper bullets (124gr for 6.5 PRC).

I’m a bit unconfident about the seating depth, especially about where to align it with the various grooves on the bullet.

I’d be enormously grateful if anyone could share any photos of seated Peregrine bullets (in any calibre).

Or just provide advice on what to do (assuming, quite correctly, that I can only follow extremely simple instructions).

Thanks!
 
Messaging JD direct from Peregrine:

“Wrt big jumps, our bullets are not jump sensitive, and there are no science behind any seating rings. We have a piece of info on our website indicating correct seating depth but that will be removed in due course. The only reason we work on certain COL is to ensure the round would fit the magazine of most of hunting rifles. Apart from that you can seat the bullet where you prefer to do so.”

So seat at book COAL if want to maximise speed / case fill. Or much deeper like I did when using faster powder (short barrel) to increase case fill ratio without adding more powder. In my experience they have been very jump tolerant so choose you powder and COAL of choice!

Oh that’s interesting!

I’ve never worried about seating depth when loading anything else, and never had a problem, but I’ve heard from quite a few people that Peregrine were very depth sensitive.

Like a lot of bullets (some exceptions). They either like your barrel…. Or they don’t!? You won’t know until you try them.

Viht powders have worked for me (not PRC mind)
 
*especially about where to align it with the various grooves on the bullet.”.
I really do not know what this means - grateful for an explanation chaps…..

I think they are a little tricky to get to shoot. I suspect longer jump is better 100thou? the best I managed was a 4” group at a hundred m then I gave up. Others, I’m sure, do better :)

I struggled in a .308 and a 6.5x55 then sold the leftover bullets and used yew tree tlr which I never managed to shoot a group larger than an 1” with so easy to load for

This seems to be a recurring theme!

I will give it a go and see what happens.

Give it a go I always thought the bullets look so pretty in there little boxes but yew tree tlr are so easy to load with and seem to give excellent accuracy and terminal performance.
Anyway I gave up a little early I suppose as components are so expensive and hard to get I couldn’t keep blasting away. Anyway good luck let us know how you get on
