This may answer a question I posted in another thread, and ANOTHER question another CGN posted in yet another thread:
I had asked about large solids as bear bullets in the 45/70, specifically load and powder info (I just got set up to reload this week... Yee Haw!)
I and the other fella were wondering if there's any restriction or hoops to jump through about shipping or recieving shipments of bullets only from the US?
silver, here is part of the final test i did last year for the 550's.....i believe i started with 36 grains and worked up to 1530fps----after that i think the pressures would put me into no mans land!!
550 grain crater
H322
Oal…..2.520
Starline brass…..2.095
Lfc….2/3 turn
Flare1/3 turn
Fed 210 primers
Test 1:….3 shots
38 grains:

Sd…….3.16
Test 2:….3 shots
40 grains:

shot 15.….1466....................................shot 16.…..1556
Break for 10 min.
LFC test to make sure the crimp is holding.
I put a 40 grainer in the chamber and put last 3 bullets in the mag!
shot 18.….1454....................................shot 17.…..1520
shot 20.….1459....................................shot 19.….-1521
I measured with the dig caliper---, brass didn’t budge!
avg………1460.5.…………………………..........….1526.4
Es……………12fps.……………………................45fps
38 grains grouped around ½”at 50 yards( potential MOA)
40 “” “” 3/4” at 50 yards.
i think the h322 is the powder for me, at least in my gun....a person who was a better shot could prob shrink those groups

.
as far as getting the bullets here--no problem...duty was about $21 cad......for 250 bullets price+ shipping was $129US.......and of course, they are gas checked!!....have some 420 grainers too, shooting at 1800fps.....hope that helps.....larry
after thought....
