Started with the max load listed for the 30-30 and the 150 grain bullet listed for LVR, this being 38.5 grains. Primer is CCI 200. Rifle is a Contender carbine with a shortened to 21 inch barrel that was rechambered to 30-30 Ackley improved. I worked up to 41.0 grains under the 150 grain Speer FP.
Chronied with a Magnetospeed the two shots measured for velocity went 2593 fps and 2597fps. Accuracy is excellent and pressure seems very mild as the primers do not re seat fully in the pocket just barely. This is getting pretty close to 300 Savage velocity. I feel I could go up another grain but can't see why and in the synthetic stocked carbine it is a bit buckish already.
