Finally got some quality range time with the Trade Rifle.
3 Days in a row of just working up loads and writing in my little notebook.
This is the result of the work up.
100 yds (known distance)
73 degrees, overcast, slight NE wind ( 5-7 mph)
Never could get a tight group with RBs with the Trade Rifle, gotta be the 1:48 twist.
At 50 yds, the RBs were within 4 inches
At 100, fell apart. Still within the 8" black, but not what you'd call tight. Tried everything from 70 grains to 110. Pillow ticking, Irish linen ( pricey) and premade T/C patches (prelubed).
I cast another batch of the 320 grain REALs ,and baby, with Cayugads lube recipe (thanks Dave!) , I think I found the diet for the Lyman.
These were the best groups (of course) at 100 yds. Lyman 57SML rear and 17A front sights.
