I have a PH 12 with 30" twist barrels, DT No 2 frame, 12.5% tool steel bolt design, PGCA lettered to 1902- but with orginal length stock to DHBP, PG- good modern dims for me (surprising as many 1900 era field Parkers had a lot of drop- older shooting style)-- I had Brad check out the barrels, use either 2.5 RST or light 2.75 AA loads- patterns show about full right barrel and imp. mod left- and they pattern a tad high-
I like it- have dropped many barn pigeons and pest birdies with it since I bought it in March this year- But as I have 4 other 12 side-by-sides with that barrel length- well- but after I shot 16 yd. trap (wanted to try wobblers too) at Lapeer- it's a "Keeper" as I can see the going away clay over the muzzles and bust it into pieces- almost automatically-
So- next year, now that I have been to my first ever "Yooper" and am hooked for life on that event- I'll use it for the pigeon ring and balloon busting derby-
Why would anyone re-blue Twist or Damascus pattern barrels anyway?
