Interesting .22 Trainer

[tbonesmith]

I picked this up today. The trigger is very light, with a cocking piece I havent seen before and the trigger is not like a No1 either. Very interestingly the trigger appears to be adjustable.
Anyone able to shed some light as to whether it is unique or the action of a pattern trainer.
It has a no2 .22 bolt head

The trigger is the type used on Long Lees. Looks like a gunsmith modification.

Is the cocking piece something typical? I imagine it improves lock time as the striker only falls about 5mm instead of about 25mm.

Ok, for starters I've never seen this type of modification before, but I do see what he's done and how.
The trigger and sear are out of a long Lee. They had the "ball and socket" joint between the two which gave a smooth and even single pull. It looks from the pics that the bloke doing the work has drilled and tapped a grub screw (is it a grubscrew?) into the back of the trigger guard to make an adjustable stop for the trigger- effectively allowing the trigger to be adjusted to as short a pull- off as required by limiting it's return travel from point of tripping.

The cocking piece is the old button type, shortened almost to the safety bent (or first cock position). In a .22 this shorter spring tension and striker travel would still give a good enough strike to ignite the rimfire cartridge, but would significantly shorten lock time and reduce the inertia. Including the trigger mods, these things all add up to help shooter repeat exactly the motions to perform a shot every time, which is very important for accuracy.

I would think the cam stud on the top of the cocking piece "projection" would have nearly needed reducing in size or removing completely to allow the bolt handle to close down with the cocking piece so far forward when cocked....

All up I'd say it's a very serious mod done by a very serious rimfire target shooter.... good find!

Yes it is a very, very fine grub screw, looks about 9ba or so, with a square section on the shank.

I've shortened a cocking piece (that was broken in the front) in much the same manner. Works fine even in .303! I did put a "Blitzschnell" spring in it from Brownell's.

Oh, I lightened it further as well. just for funsies, and all...
