............Years ago I picked up one of these from Navy Arms. I believe it was a parts "Put Together" after Parker Hale had gone out of business. Not known to me then, but recently I understand that Navy Arms had bought the moribund Parker Hale company ...................Or something like that. In any event. mine is all marked Parker Hale and P-H on smaller parts.
It has the 5 progressive depth grooves and 48" twist. We were shooting what we called the "Burrito Shoot" some years ago, which was 5 rounds at 50 yards and 5 rounds at 100 yards for score. We'd all kick in a buck and high score would win the pot. A couple of the guys developed gas when we'd shoot MLR's as they didn't like the clean up I suspect.
In any event, in our last match this is what I shot at 50 yards:
And this was the last 5 at 100 yards:
The matches were fired standing offhand. Prior to this they had already ruled my Whitworth as being "Rifle non grata", and this effort sealed the fate that no one was interested in campaigning MLers in the matches anymore In case anyone is interested, the load was a Lee Target Minie' over 40grs of Elephant 3Fg, and the lube was Ox-Yoke & an RWS musket cap.
