Original post says it has a TSE adaptor, presumably the same as the old Neilson adaptor which allows the bolt lugs to lock into that, rather than the barrel itself

Hi Tom, BBT went tits up some time ago, the proprietor was by all accounts a strange individual.

Mine arrived a couple of days ago from the link posted above by ColinBR, thanks for posting that £500.00 for the device incl postage, £112.00 VAT. Took about 4 weeks from ordering as it seemed to have been in a distribution centre en route to the airport for over a week. A shooting friend also brought one to the range on Sunday that he bought from Amazon, paid a few quid less than mine. Maybe you can pay the duty up front with the purchase price for a discount?

You will have to check with the gunsmith who fitted the barrel, what reamer he used or what is stamped on the barrel, as the cartridge designation?

Nick, Whatever foxy has in stock! Seriously, I wouldn't recommend using a CCI standard small rifle primer in the 6BR as you may increase the chances of blanking and piercing the primers, I've seen it happen enough to know that small rifle magnum primers with their thicker cup are the way to go, especially if you are using a factory action and bolt that has not had the firing pin bushed. Now I'm sure there are those that get away with the standard small rifle primer in their rifles, but why risk it when it is a relatively common occurrence? I'm sure Brian has some S & B small rifle magnum primers in stock which I will be trying when my stock of CCI450's is exhausted.

Your case measurements can't be correct. If P2 (the case diameter at the shoulder) was bigger than at the extraction groove (P1) the case would be wedged in tight. Maybe you have those numbers transposed? My Shehane fired cases measure .4860 at he shoulder and .5005 just above the extraction groove. A standard .284 would be .475 at the shoulder.

N160/N555 would be a better fit. I use N160 in the 6x47 Lapua with 107SMK

Have you read the post from English Rifleman?

I think he means if it's not a Joe West stock, don't send it to Joe West for finishing.

Quadlite action

Hi Mate, You shooting this Sunday? I'll bring them along if so.

Hi Stu, No worries, just let me know and I'll bring to the range.

Hi Stu, Yes, still here.

Unless you have the exact same comparator the dimension is meaningless. Unless there is another way of measuring cartridge base to ogive I am not aware of. As Garyw says, best way is to give a couple of dummy rounds to the gunsmith and hope he is able to measure and replicate that dimension. Keep another dummy round to check yourself if he screws up.

I don't shoot the 6XC but it's very close neighbour the 6 x 47 Lapua and I'd echo what John HM has said, N160 is what I use with 107SMK. N560 will also work but I got a few hang fires with certain primers. I've also used N550 but I think probably a bit fast burning for that case and bore diameter with the heavier bullets. Probably N555 would also be ideal.
