Well I finally managed to wade through the snow and get out to the range,and discovered that 53.5 grains of reloader 7 makes me very happy.
The rifle- Ruger #1 stainless tropical
The load-
hoch paper patch 330gr out of adjustable mould .406 diameter
powder-reloader 7...53.5gr
Alloy- approx 20-1
paper- bienfang tracing paper... 2 wraps... .412 patched bullet diameter
Lube-rooster labs liquid jacket
Primer- federal 215 magnum
Brass- Hornady from the 50rd boxes
Average velocity- 2420fps 8ft from muzzel at 100yds 2109fps
The rifle was a 40th birthday present to myself (being selfish I guess)and has not seen a single jacketed bullet from my hands just that wonderful lead alloy that we all love. The cartridges were assembled in a combination of hornady and CH-4D large neck size die with the .434 diameter insert. Overall length loaded round 3.087 which has the paper just engraved by the rifling I have found this to be the most accurate with the bullet just started. Recoil is stout but managable from bench and with a 22fps extreme spread for 10 rds and a standard deviation of 7.41 I am pleased.
When loading the bullet I have found that with the .410 inside diameter of the neck a very small amount of imperial sizing die wax on the base really eases the entry of the bullet without distortion...I would not use this load in anything but the #1!! even though I show very little sign of pressure it is again a stout load!!
The target is todays complete with flyers and bad technique 6 into one 4 outside.
