Post photos of your jungle carbine and I'll post some of the one that I just got. It's definitely got that "been there and done that" look ... but it probably has.
As for the Star B issues with mags, that's a long and detailed story, but in most cases (pun intended) they work better with steel-cased ammo like TulAmmo. Brass-cased ammo doesn't work as well in most Star Bs. The short explanation is that brass cases are slippery against each other and move out of column easily in the Star B mags. The rougher steel-cased ammo tends to stay stacked in column better.
Yeah ... you'd think that the more expensive ammo would work better, but not in this case.
To keep this thread from becoming about Enfield Ill try to find the old "Enfield Porn" thread.
