Rick--Used one a .300 H&H a little that I borrowed, and liked it a lot. Have used various other .300 mags (Win., WSM, Wby., RUM), and decieed to try the original. The .300 H&H is easy to load for, and does anything a 7mm STW will, if you use the right bullet. It's just an "antique" version of the .300 WSM, but the cases feed super easy. Am getting 3050 with 180 Partitions into .6-.7 with R22.

<br>Sitka Deer--Headspacing isn't much problem in a Model 70, since you have to screw the barrel in tight enough to get the extractor cut in the barrel lined up with the extractor, but have checked it with gauge too. Works slick.

<br>Am doing the same thing with a Remington 700, with 26" .270, 22" .30-06 and 22" 9.3x62mm barrels, and will scratch witness marks on each as they're fitted by various gunsmiths (the '06 came on the factory rifle) so they can be fitted exactly the same each time. The witness mark on each barrel will line up with one on the bottom of the action.
