That's correct! The 300 Sherman PRC S.I. will have reamers available by 1/1/19. Most of you have likely heard about the performance gains in the Sherman cartridges. The 300 PRC S.I. is no exception and has some really cool added appeal! The S.I. version will allow firing Hornady factory cartridges in your chamber which are properly head spaced (just like the 280 Remington/280 a.i.) After that, you simply use your Sherman dies and fire formed brass to reload as usual. The difference will be the 225 ELDM will run near 3000 fps in your 26" barrel and have less case stretching. This is not speculation, I've been shooting one for 4-5 years with modified 375 Ruger Hornady brass. With my 28" barrel, I run the 225 at 3050' and get 3-4 loads on my brass. For those who already own the 30/375 S.I., I haven't forgotten you. The new reamer will clean up your chamber and actually give a slight boost in performance. This cartridge has proven to be superbly accurate and is a long range hammer on elk. Below is a pic of the 280 Sherman, based on the 270 W case, next to the 300 PRC S.I.
