Over the years I've owned a half-dozen or more rifles chambered in .300 Savage, most were Savage 99's, two were Remington bolt action rifles. Like any chambering where lever action rifles are a consideration, factory loads, and load data for reloading result in pressures designed to be safe for lever guns, as a result bullet velocity suffers. In short, the loads don't take full advantage of the much stronger actions of bolt (or many single shot) actions. So it was for the .300 Savage for many decades - great round, just not loaded to "modern" pressures, or velocities.
Well, that all changed. Sierra pressure tested loads for the .300 Savage using Varget powder, and Sierra 150-grain jacketed bullets (Pro Hunter). Ramshot (formerly Western Powders) followed suit and developed loads for 150-grain bullets using their TAC powder. The resulting loads transform the old cartridge. I carefully worked up loads following Sierra's load data, and was able to achieve nearly 2,800 fps with the 150-grain Pro Hunter. Accuracy was equal to or better than the loads I'd been using for many years, but the velocity gain is over 200 fps. Big deal? Normally I say "no", however in this case when you look at exterior ballistic tables, it allows velocity for penetration and expansion out to 400 yards. That's a 100 yard advantage over the responsible capabilities of previous loads, and takes the .300 Savage out of the "brush gun" category, and makes it a legitimate long range rifle.
All this in rifles that were the original "lightweights" - Savage 99, and Remington 722 - I like it.
