Very nice one!
I got the renewed 1942 out to the range Saturday. Inletting and fitting the new foreend was quite tricky. Even the trigger wouldn't function until I removed wood to fit the trigger plate better. The design is far from simple to work with, and the push-pull-push arrangement on the barrel makes everything extra difficult. You can't just clear out wood around the stock, stick some cork at the tip and call it good.
So my group size was reduced. Loosening the barrel band improved things a bit, but it still wasn't as good as it originally had been. So it's back to the drawing board. The barrel is sitting very tight in the nose cap, which it apparently isn't supposed to be. So I suspect what was happening is the nose cap gripping the barrel fast while the mid-barrel band just torqued it downwards. The barrel should not float, apparently, but it does need to have a little wiggle room between the pushing of the front end spring loaded plunger and the pulling of the barrel band. Both are spring loaded so you should be able to grab the crown and move it slightly even with the nose cap on.
I'll play around a little more here but I may need to try a different nose cap. If it's firmly fixing the barrel's end then nothing I do to improve the rest of the fit will matter much. The SMLE may have been the best battle rifle of its era, but it was a complex beast for sure.
