I have had just about every small caliber 17 MK through 6mm Remington and the Most accurate CONSISTENTLY were the two Remington XR-100 204 Ruger--The 1st was purchased when 204 Brass was like "Hen'sTeeth" it would shoot either 29 Sierras or 40 V Max less that .3 rechambered to 20 Practical and the accuracy never changed . After it was stolen I purchased another and it too will shoot BUTT only the 39 BT as the V-Max just does not quite like the 12 twist . I posted pictures a while bac of several 3 shot groups consisting of H-4895 -7 1/2 Winchester brass with various amounts of H-4895, The only other calibers that would shoot like this were a 222 40 XBBR and the 6 BR/Dasher
Good Luck
