Firing Pin Bolt Bushing

The factory have never made a 6.5 x 47 Dave.

Any sold have been fitted with an aftermarket barrel from the vendor.

................ and I've no doubt that AI doesn't offer a 6.5X47L (or 6BR etc) variant because of this very issue. At its heart, AI rifles are designed to be used in the roughest and dirtiest of conditions and still give 100% reliability. Dealing with finicky small primer high-pressure cartridge designs doesn't come into that and what suits this cartridge might degrade the rifle's reliability and longevity in its primary role. Producing a special bolt and firing mechanism for those who want to use the rifle in unintended roles is actually the RIGHT answer to the conundrum; changing the standard design, the wrong one.

Unfortunately we have a raft of specialised match cartridges (and variants of non-specialised older designs such as 243 Win and 260 Rem) now being produced in SRP form and many of the people who end up using them are either unaware of, or underestimate, the potential pitfalls. Once 243 SRP brass becomes common, I'm waiting for the unwary / unwise to start shouting .............

It didn't work in minus 20-deg C temperatures on my deerhunt.

Why do half my primers have holes in the middle of the cup after firing?

I've lost lots of velocity with my XYZ powder load and my zero was miles off at 300 yards. (I've already seen an American match shooter say that Peterson SRP brass simply doesn't ignite compressed Hodgdon H1000 loads properly in any temperature levels in 243 115gn bullet loads giving an MV drop and large ES values.)

What! You mean I've got to retune my load and have two have two different charges, one for LRP brass, one for SRP and the zero might vary?

Interesting thank you Dave. I always believed that the Options available on sporting services website were factory options. It’s certainly not clear they are not.

I spoke to sporting services a few weeks ago and they (he) assured me that all of their barrels were from AI via the other company owned by its directors (walls and irwin ltd) and were of either lw or border in origin. He confirmed that none were chambered by any other uk gunsmiths and all were from the AI factory, in any calibre you wanted. Someone isnt telling the truth me thinks.

Any factory barrel carries a serial number.

It doesn't match the gun's number, it's it's own serial number, used to identify the make, and period of manufacture.

If the barrel has no number, its not a factory barrel.
