I have a barrel sitting on the shelf to make a 45 rifle if they changed the Illinois law allowing rifle for deer. Always thought it would be a 45 win mag well the law changed and they are allowing any straight wall case. So I have been thinking 45 raptor but my barrel is 1 in 16 twist kind of fast for that case. Now I'm thinking just make a long 45 win mag 1.5 or 1.6 inch long case. Any thoughts? Photo is standard, 1.5 then 1.6
