I know, I know - I'm almost not even worthy to post on this forum with my double rifle, but at least I am now in the market! About 9 months ago I purchased the Remington SPR22 in 30-06. I took it to the range and had a blast shooting it. Lots of folks gathered around to gawk at it too - it was kind of fun. My wife has just gotten me the SPR22 in 45-70 Govt. for Christmas, and I'm counting the days until Christmas! Here's my question - will it be safe to shoot 45-70 loads that are 405 gr? While looking at the various loads available for the rifle at Cabela's the other day, I noticed several varieties of loads ranging from 300 gr. and up. The hottest load was the 405 gr. which is also manufactured by Remington. It states on the box that the load will work in all 45-70 rifles. Any recommendations or advise? This is my first post - what a great site! Thanks, Christopher
