257 Ackley Improved
In The Ultra Light Arms Model 28 rifle
The 257 Ackley teamed up with this very light rifle is probably a great choice for a mountain rifle. The rifle weighs 6.16 pounds complete with a Leupold 2.5-8X scope installed.
We used Remington 257 Roberts brass, and the RWS 5341 primers in all the following loads. All groups are 3 shots at 100 yards.
