Well I got to the range today w/the 340 30-30and a sporterized 1903A3.
The 340 did reasonably w/the Lee 200 cast boolit and 13 gr H4227. 311041 (old) and 311284 were less than i expected. Need to up the 340 loads w/the Lee boolit and see what happens.
The springfield did pretty good w/the Lee 200. RL7, 0.311, wlr primers, teflon tape lube and LC Match brass. Started at 24 gr and went to 25.5 in 1/2 gr increments. Groups tightened up as the load increased w/the best at 5 in 0.95. all at 50 yds. Redfield rear sight and a sourdough front w/brass insert. Stock A3 bbl cut behind the front sight and a good crown. I will try up to 26 gr RL7 and then take the best load and play w/seating depth and match prep the brass.
No leading. No chronograph so no idea of velocity.
Am looking for a base that will fit the existing hole spacing to mount a Lyman globe front on the Springfield. Champions choice may have what I need. I could be REALLY happy w/ 1.5 to 2" 5 shot groups at 100.
Next step for the 340, in addition to slightly hotter loads, will be a FP340TK rear as the std rear sight is a little rough on the old eyes.
Any idea of a velocity range that i am in would be appreciated. This should be a good Bambi load.
Cheers
Don
