hello..
i am thinking of a rifle for some targetshooting , and the rolling blocks seem to be like a magnet to me..
i have had one , but ive sold it some years back.:banghead:
done a little reading and comparing , and one thing caught my attention.
reading in my lyman reloadbook ive found a data for the 45 70 cartridge , and its especcially for the trapdoor springfields...and i quote "also suitable for rolling blocks , sharps and replicas of these rifles ".
exclusive use of cast bullets is recommended for the older original rifles.
i will take one line of the manual :
lyman bullet 457193 , 405 gr , powder imr 4198 31.5 gr velocity 1312 pressure
c u p 12.400...
for the comparison :
lyman bullet 457193 , 405 gr pyrodex powder 60 gr velocity 1216 fps pressure c u p 15.500
so , with the use of blackpowder or nitropowder , the pressure should be safe
if the levels are kept down i would say...?
this is the data for the 45 70 cartridge , the swedish rolling blocks are more like a 50 70 cartridge [12,7 x 55 mm ]
my thinking is that it wouldnt make a lot of difference...
so the question i would like to ask is if any of you guys have tried to shoot the older original blackpowder guns with the newer nitropowder?
yes i know there are replicas , but imo thats waht they are , replicas..
any advise, experience?
thank you....greetings from holland !
