I certainly woiuldn't be lapping the barrel. Don't forget, lapping the barrel is just another or polite way of removing some of the bore material. Additionally it's a good way of rounding the remaining edges of the rifling. The days of lots and lots of gauges are well past. If a snioper rifle passes the EMER accuracy test and the plug bore gauge runs, then the barrel is serviceable
That's right BAR. In the days of the No4T's, some tired T's looked like they could do with a new barrel. A simple job at the bigger Field or Command workshops, the sniper would kick up a fuss if you tried to 'improve' it. As far as he was concerned, if it shot well and was accurate, that's all that concerned him. Same as L42's and later the L96's. In fact, L96's were quite notorious for gleaming new barrels tat would group well on the test range, from the layer but were rubbish at 400 yards, the optimum sniper target range
Andy, you don't have to use solder paint/paste. You can use conventional rosin fluxed solder. I just find the application of Fryolux quicker & easier. I just checked for availability on the UK version of 'that' internet auction site, & a number of sellers came up. I'm sure if you go on the US site you'll find an equivalent.
Roger, I figured as much, and I have plenty of old school solder, but solder paste seemed interesting so I figured I might get some and play with it just because I had an excuse on this project.
Crowning tool is here. Pondering on my preferred method of dressing down the ding a smidge with the tools I have at hand before I deploy the crowing tool.
