Re: what is a palma contuor?
Palma is a long-range prone game played at 800, 900 and 1000 yards with .308's, restricted to sights and bullets of 155 grains or less. The Palma taper barrels are required to get the 30" lengths needed, and still be light enough to conform with both rule restrictions, and the ability of most shooters to support the rifle during strings of slow fire.
I use a 30" Krieger on my Model 70 Palma rifle for both prone and across-the-course competition. It's a long darned thing, but easily handled at the range. Balance is very good for a rifle shot primarily from prone.
The muzzle can be turned down for a sight band, and mine is.
