Mac; My rifle was done by SSK and I'm really pleased with the final product. I originally wanted to do a 577NE or the 600JDJ, but the logistics weren't realistic. I wanted to go sans muzzle break, maintain good field carry weight, and retain the Ruger appearance. Feeding one of the giants was also an issue. I'm glad I went with the 500 as it's been more fun than I can describe.
Gryphon; John was a cousin who was sadly afflicted with the less impressive genetics of our family....
Rimshot; I've been playing with 375s for quite some time and I shoot mine a lot. Here are a few loads that have been favourites for various disciplines:
72.0/RL15...Sierra 250 SPBT or Nosler 260 Partition Great for varmints & medium game
80.0/RL19...Sierra 300 SPBT Excellent long range performance
77.0/IMR4350...Sierra 300 SPBT Another great all around load
67.0/IMR4064...Nosler 300 Partition My big game load
I'll try to mooch a digital camera next weekend and shoot a couple of pictures of the 375 and the 500.
Anybody do any paper patching for their big bores?
