Help with Small magnum primers

[plumber01]

This might be one for the Muir and co , I use 308 palma brass , I'm having trouble getting small magnum primers , question is , can you use BR primers, or even small rifle primers, and what might the effects be, I tend to use about 44.4 N150 with a lapua scenar 167 gn, this is for target only.
I would like to know, is it safe,? and what is it likely to do to accuracy / velocity

Look up targetshooter online magazine. I did a three-part examination of the issues involved and tested some 15 models in 308 Win Lapua Palma brass with coincidentally the 167gn Scenar and Viht N150.

for the final part, but I'd recommend looking at parts 1 and 2 re the issue of SRP types and classifications.

Depending on your rifle's firing pin to bolt-face aperture fit, the thinnest cup models, Rem 6 1/2; CCI-400; Winchester WSR may prove too fragile and crater badly, worse 'blank' (ie pierce blowing a disk of cup metal back into the bolt).

BR models are in effect SRMs so far as cup strength goes.

Loads can be very primer sensitive and often need some fine-tuning on changing the model. As a rule, the smaller the cartridge and powder charge, the more this applies - 223, 6.5 Grendel, 6BR etc can all behave differently on a primer swap with no other changes.

If you can get them locally, I'd recommend the latest version of the Russian Murom KVB-223 standard primer, packaged as Small Rifle Competition, or something like that. For Russian primer fans, a warning. When current in-country stocks run out, there will be no resupply - the import ban on Russian products is now being enforced strictly I'm told.

Which AI? AI didn't transition to a small firing pin until post 2014, which if your rifle is older, you'd have a chance of needing to have the bolt face bushed, and firing pin turned down to use SRP. Not an easy task considering the hardness of the AI bolt heads (ask me how I know).

If it's a short action, they do sell now complete bolt bodies, FP's and bolt heads, but that gets expensive very quickly. Not sure how that is affected by your laws requiring serialization of bolts to firearms...

Not sure if this is actually a requirement?

Remember reading on here about a guy who bought a Remington 783 (ooohh...) and asking if there was a problem if the bolt serial didn't correspond with the receiver.

The gunshop, Raytrade (importer) and the proof house all shrugged their shoulders and denied responsibility!

Probably got put back into the wrong rifle when being proofed for a second time... seems what Remington do/did was insufficient

Can you buy more and keep some for me?

Pretty Please?!

 

[MarinePMI]

I think I'm good for a while...though that case of 9mm at the bottom left is almost all gone.

 

[plumber01]

Thanks Marine PMI , yes AI is 2019 model, so OK with SRP
cheers

Can I bring them into the UK in a car? "I"ll be back" beginning of March, happy to help if it is legal. Do you need a UK FAC now to posses/buy primers? My FAC I let lapse a year ago as I don't do stalking in East Kent, there is nowt there that I have an access to. I just checked egun they have some left 4x boxes. Cost 149 euros plus 16 euros special postage to me. Works out at around 0.033 cents per primer.
