dont do it, there are better carts out there, such as the 204, 17fireball, also called the 17 mach 4, and maybe the new king of them all; from the savage custom shop, the 5.35c. a 32 grainer out of this baby leaves the muzzle at 4800fps, a 40 grainer is still sizzleing out at 4300fps from the muzzle.
it uses about 80% of the powder of a 22.250, but because of it's extra long neck, and far superior case design, with radial shoulders, has way better bbl life, and heats the bbl less than even a 223. The 17mach 4, or 17fireball, will be a remington factory cartridge this year, the savage 5.35c , im not sure if it is going to go factory or not, but Savage has all the specs , brass, dies, etc., for you to make.
The 17remington , is way overbore and bbl burining for the round, and the others are both more efficient, and faster, than the 17 remmy. the 204, and the 5.35c will have both better b.c. and s.d., plus the speed will let you do the explosive hits, all the way out to 500 yds. The 17mach 4 or 17fireball, is as fast as the 17remmy, but less powder, and better bbl life.
