I had two, one a 94 Win and the other a Marlin, rechambered by Paul Rogan here in Whitehorse. Paul sold the reamer to David Henry in Alberta.
Both rifles get 150 gr bullets well over 2600 fps with 150 gr bullets out of their 20" barrels. 170 gr Speers get way past 2300.
Velocities recorded over my Oehler Model 33. Primer pockets still tight after five reloads.
The 30-30 Ackley just simply works.
