--5mm Remington Rimfire Magnum--Created in 1969, this great little round i the forebearer of the current 17 HMR and 17 Mach 2, 25 years before it's time and better the the newer ones. It's listed as 38 gr bullet, 2100 fps.
--30-06 Improved (Ackley)-- A 30-06 with less body taper and more steep neck. The imcrease powder capacity and efficently of this round added to the fact that weapons chambered for this round could also fire standard 30-06 ammo is a huge bonus. This round will pop out a 150 gr bullet at 3070 fps and 3150 ft-lbs of energy or a 180 gr bullet at 2825 fps and 3200 ft-lbs of energy. This is quite an improvement over the 30-06, matching 300 H&H Magnum and approaching the 300 Winchester Magnum in a standard length action. (Very similar to the performance of the 30 Newton developed in 1913).
