no4 mk1 vs mk2 trigger

[ssj]

In terms of accuracy I wonder if its that the post-ww2 5 groove barrels in mk2s and 1/2 - 1/3s were a better quality? and hence the mk2 / FTR'd were more accurate for this main reason. The trials rifles were mostly? converted to Ts? with pre-war 5 groove barrels? Ive seen comments that the 2 groove were not much worse than the 5 groove, but really if the 5 groove were dodgy by then as well. Ditto L42s? ie a better barrel?

There were zillions of student trials and tests between two groove and 5 groove barrels and there really was no difference between the accuracy of either that could be put down to the rifling. It was said that the two groove barrels stayed more accurate for longer for various proven and unproven and even mystical reasons. Some could be described as simply magical reasons judging from the way some papers were written!

It really is all about imparting gyroscopic effect to the projectile plus the foibles of .........., well everything else on the particular day in question really!

I modified my No. 5 (with No. 4 action) some time back with help from Peter L. Maintenance is definitely easier and once the trigger pull has been customised to one´s personal taste, it does remain like that, even after re-stocking. Minute changes in the trigger pull are, of course, subjective. But it does increase confidence that moisture in the wood is no longer an influence.

Hi Peter,

I read your articles on correcting the trigger pull and very interesting and informative they were. Mine was an extremely heavy single pull that made the rifle very uncomfortable to use. I bought another standard trigger off ebay which gave the exactly same results. After reading another shooter's testimonial I decided to buy the aftermarket trigger and I have to be honest it made a dramatic difference even though I have not optimised the set-up.

I have a AJ Parker range rifle with a modded trigger and frankly it is still too heavy. Its also getting hard to locate seers and cocking pieces without having to spend a small fortune. So Im looking for an aftermarket trigger so its adjustable. Thanks for the hint, I'll go look.

Thanks, Ive not seen that written anywhere....

The trigger pressure should be between 3-4 and then 2nd pressure of 5-6.5 lbs pull-off. Any less than that is dangerous in my opinion but that's just me. And there's no reason why a No4 trigger mech can't be made superb. There's only two moving parts rotating on two axis pins

Haven't seen the true reason for the change to body mounted triggers written anywhere! You have now! The whole warts an' all story was written here a few years ago as I recall. Just consider. On an Armourers bench, setting up a few triggers on Mk1's and 1/1's a day was no problem at all....., even after fitting replacement fore-ends. But think about unskilled women fitting-up thousands a day in the fitting-out bays! Now all they had to do was fit the actual fore-end without the additional palava of fore-end off and on and off and on again just to get the triggers correct!
