It would seem that the L144A1 firing pin is a very different design that that from the No 8.
It looks like that there will a very high probability that the NSPs (firing off the action of an empty chamber) will result in damage to the firing pin as it will impact the chamber when the action is fired off. The "pin" on the L144A1 is actually a rectangular strip of metal & the bottom forward corner strikes the edge of the cartridge.
The No 8 firing pin & associated headspace was a very different design, hence this was not an issue.
So, how will SASC deal with this? It seems to me that potential damage to the firing pin has not been taken into account (& as the draft "manual" for the L144A1 mentions at the outset webbing, & checking webbing pouches as part of the pre-firing drills, it would seem that their mentality for military weapon handling hasn't taken this into account.
The rest of the "real world" firers who use .22 competition rifles either don't dry fire, or use snap caps/dummy plastic rounds. This would probably fall under the SASC's definition of blank rounds!
The rest of the "real world" firers who use .22 competition rifles also use breech flags as the way to show to all firers/RCO that their rifles are unloaded & safe. Until the manual was issued for the Scorpion air rifle, we used to use .177 breech flags - but now of course follow the full NSPs = firing off the action on an empty barrel & leaving the bolt CLOSED!
Anyone got the direct contact details for the person(s) dealing with the L144A1 at SASC? Someone has got to tell them that they need to (a) change the proposed drills & (b) move away for the military centre-fire NSPs that should not be linked to simple single shot .22 bolt action rifles.
The complete album of photos is here. The stand looks to be a complete design "fail" - why not a standard 2 leg bipod stand as used for all other tgt rifles (including the L81A1)? It's got a hand rail too, so would be a much better option. You can get folding ones that remain attached to the rifle, but much more expensive.
It doesn't give a definitive comment - but guessing that this is the safety catch?
I can't see a front attachment point for any sling - but I am reliably informed that the sling is made out of a "bungee" material" = absolutely useless to get a constant tension
