  1. Thank you everyone, for your advice. I’m really pleased to hear that I can have the bolt face opened up to use 6BR, as this was always my preferred option, so that’s my way forward now.

    I’ll be contacting a couple of gunsmith’s to get this done and then see you on the firing line. 👍

  2. Having come to the end of the line with my 6PPC barrel, I was looking into re-barrelling it for longer range benchrest competitions - 600 or 1,000 yards, also back to 100 yards if that's possible.

    However, given the bolt face on my Sako 75, it's not feasible to get a 6BR or 6BRA, so I was wondering if anyone has had any success with the 6mm ARC?

    If you wouldn't mind telling me of your experiences, good, bad or indifferent, I would be very interested to hear.

    Also what powder, barrel length etc, would be great.

    I was hoping to use Berger 105's if it's possible.

    Thanks in advance for your input.

    Cheers.

    I got one from Area 419 but they will no longer, at Garmin’s request, ship the Xero to the UK

    Thanks for replying John.

    I tried ordering one from Area 419 yesterday and they sent me an email today, saying they won't ship out of the country anymore.

    That's why I thought I'd ask if there was anywhere else.

    Is there any particular reason why Garmin won't let this happen, do you know?

    The CCI-400 and Rem 6 1/2 were originally designed for the .22 Hornet, .218 Bee and similar. In addition to these being relatively low pressure cartridges, they needed rather 'soft' (read 'thin') cups as in poorer times than now many rifles were built on converted rimfires, old Martini Cadet and similar actions with weaker and lighter mainsprings/strikers. When Remington introduced the .222 Rem in 1950, a ~50,000 psi cartridge, the 6 1/2 was deemed too weak and the first SR 'magnum', the No. 7 1/2 was introduced to cope with the higher pressure. As with most SR 'magnums', it was no 'hotter' than the standard model, but had a thicker brass cup - 25 thou' vs 20 thou'. (The later / current 7 1/2 BR is more aggressive having been introduced alongside the .17 Rem cartridge that needed a higher brisance primer with some powders.)

     

    In the 223, it's always better to use the thicker cup models, although you can 'get away with it' with weaker designs depending on 1) the pressure you handload too. (In a standard shortish freebore chamber the 77 SMK + 24gn Viht N140 would likely be approaching full pressures, rather less with a Wylde or longer freebore chamber.) ........... and 2) the nature of the action and how much clearance there is between the firing pin and its hole in the bolt-face. A loose fit facilitates cratering, and at higher pressures 'blanking' where the metal disk of the pin indentation in the primer cup detaches and either ends up inside the primer or in some action designs is blown back into the bolt body. (The latter happens with ARs and similar with a floating firing pin and no firing pin retaining spring, also thin-cup primers aren't a great idea in such actions anyway, as there is a small risk of a slamfire caused by the pin's momentum as the bolt slams closed under spring power. This is why there are special military spec primers such as the CCI-41 for such rifles.)

     

    Cup thickness is as follows for US models

    20 thou' ............ CCI-400; Rem 6 1/2

    21 thou' ............ Winchester WSR

    22.5 thou' ........ Federal 205 and 205M

    25 thou' ........... CCI-450 and BR4; Rem 7 1/2 and 7 1/2BR

     

    European primers vary. The original Russian Murom / PMC SR primer (KVB-223) with the bright copper colour metal was very thin/soft and blanked easily. The last of the KVB-223s available here before the import ban on Russian stuff was sold as the 'SR Competition' and is sturdier, but can still be blanked with a not massively hot a load in the 223. (I sometimes wonder if this is a procurement or production QC issue rather than the design as it occurs randomly.) The KVB-5,56 and later KVB-223M are both tough primers, the former with a mild explosive pellet, the latter more powerful to cope with some modern ball type powders that need 'warmer' ignition.

     

    Fiocchi, PPU, and S&B seem fairly sturdy, but the S&B marque has both 'SR' and '5.56' versions, the 5.56 obviously made to a military spec. Can't comment on Ginex as never seen any, likewise  the RUAG/RWS/GECO (same thing; different labels). However as Nitrochemie uses RWS in its 223 RS40/77 loads data with a max pressure over 58,000 psi, it must be robust.

     

    South American CBC Magtech 7 1/2s are as the identification number denotes, a 'magnum' type with a thick cup. IME, it's a tad 'softer' though than the equivalent Remington or CCI SRM / BRs, but is fine in most 223 bolt-actions, and the late 'Bradders' both sold them to his AR shooting customers, and used them himself in CSR loads. (Excellent primers and FAR better value than any US model if you come across any, but strangely they're not 'rated' by most British handloaders.) 

     

    If you ever come across 20th century Vihtavuori primers in the old blue and orange packaging, these are the weakest of the weak and blank very easily indeed. (Viht is restarting primer production next year or maybe the year after as a result of the current western European security crisis allied to Finland's accession to NATO that sees it switching from LRP 7.62X39 to SRP 5.56 and one assumes that when its primers eventually reappear for sale to handloaders the SR versions will be 'tough' models.) 

    Thanks for that detailed reply, Laurie, it's really appreciated.

    As a brief aside, would the 6 1/2 work with a lighter 60gn bullet, with a psi of around 43,000 and 23.0gn N140?

    There is also the option of the "Geco/RUAG" primers.......

    Or should I just right off the whole idea of using 6 1/2 remingtons altogether and go back to my original load and bullets with the CCI BR primer?

    Just looking at options before I run out of the CCI

    223 is a fairly high pressure cartridge, and it's possible that the primer will pop and burn the bolt face........I speak from experience, having once mixed up some spilt KVB Magnum and Standard primers.

    My 223 bears the scars...

    Pete

    Thanks for replying, Pete.

    It's not looking like a good idea to use these, then???? 

    Oh well, I guess I'll continue with my existing primers and keep a look out for some coming up for sale.

    Cheers.

  6. I was hoping someone with more experience than me can offer me some advice, please?

    I have a .223 Tikka T3 Supervarmint 20" 1:8 barrel and was going to get some Remington 6 1/2 Small rifle primers that I've seen for sale; but I have seen an advert on here that says they are not suitable for use in a .223......can anyone confirm if this is correct, please?

    I am using 77gn SMK's and have been loading with 24.0gn N140 and BR4's.

    Looking forward to any assistance.

    Cheers.

  8. Nightforce NX8 4-32x50 F2 - SFP .250 MOA. MOAR Reticle.

    Has only been out 4 times to the range. It’s never been used outdoors in wet weather, as the range I use has covered firing points.
    I’m wanting £1,450.00 ovno collected + postage of your choice, if you would prefer. Excellent condition and comes with original box and all accessories.

    I’m not including the SPUHR mount, but can be bought together if wanted.

  9. Just a general thought whilst I was at the range today, as to who actually carries with them a first aid kit in case of an emergency etc whilst out shooting, be it on the range or the land.

    It was because one chap came to the range today, who always has one with him; and I realised he was the only person I knew who did this.

    Now, with a sense of cautious concern I believe it should be a common practice, as you never know if anything was to happen, how injuries could be treated whilst other help was being sought.

    Having said this, what would be your view on the best items to include within a "Field" First Aid Kit?
