The 300 Sherman shares the same case design as the rest of the proven bore sizes and is the most you can get out of an ’06 bolt size! In fact, the 300 Sherman will equal the WSM and is right on the heels of the 300 WM. It is a very easy and inexpensive conversion of your old ’06, or just start from scratch and build a great performing custom.
The 300 Sherman is capable of over 3000 fps with 200 grain bullets, and is suitable for any game on the North American continent with the many excellent bullets offered. A 1:10 twist barrel is recommended for best overall performance. Powders ranging from H4350 to RL26 are best suited for this cartridge.
