The SS would be legal for side matches( Long Range) as long as it's not ported and has no scope mounted, in caliber 30-30. The .35 Rem is not a legal caliber for Cowboy Action.
The rounds have to be lead, no jackets, although for long range you can use gas checks.
Here's the URL for SASS's Home Page, you can find the rules concerning legal guns and calibers here.......www.sassnet.com
Sorry, missed the caliber on first read, 45-70 is a legal caliber for long range side matches as well. Again, lead bullets only, but you can have gas checks.....Buck 8)
Any of the big bore levers in approved calibers, no scopes, iron sights or tang sights only. .35 Rem is too modern. Let's see, just off the top of my head, long range calibers.....32-40, 38-55, 38-56, the Win. '76 calibers( can't remember them exactly), 40-65, any of the original Sharps calibers, 45-70, 50-70, 50-90, the 30-30,too. My LRR's are in 38-55( Marlin 1893), and 45-70( Wesson&Harrington Buffalo Classic).........Buck 8) :wink:
Of the large rife calibers currently offered in Marlins 35Rem. and 444Marlin are not allowed. Reason being the 35 is to newer (1908), and the 444 dose not resemble any original lever gun cartrages (at least according to the goveners) . Also the rifles do not have to be cowboy style i.e. octigon barrels. There are restrictions tho. No recever mounted sights, no optics moden or otherwise, no compensators, wood stocks are required, as are lead bullets. You can use cas checks, tang mounted sights, and spirit levels. Personally I have found the longer and heaver the barrel the better. More sight radi, and more stability on the cross sticks. These are the rules for a SASS sactiond match, local monthly matches may have slight variations according to the match director. One more thing, there are other non SASS long range matches out there using cowboy style guns with different rules.
