My son and I both have Model 70 Featherweights (1980 version).
They love the 117 gr. Remington RN (yellow/green box)which are no longer manufactured (so only a lucky find at a gunshow). Accuracy and groups are always more than satisfactory.
However, other common/still available factory rounds are proving very tempermental in both guns. Groups expand and move at random from one day to next.
Scopes mounts are solid and scopes are fairly new Bushnells.
Is this a problem in other rifles chambered in 257 Roberts?
