I was just looking at these rifles on the Rem. site. That single shot SPR18 look pretty ugly to me. Now the double rifle SPR22 looks nice. I'm with you rick, that double rilfe in .45-70 would be sweet. Only thing though, It looks like it won't take full house .45-70 handloads. You have to keep pressures down to 28000 psi (standard factory loads).
Oh well, I guess I won't be able to use it on the cape buffalo that keep digging up the yard here in my PA home.
