CC,
I have a Ruger Safari mag in 375 H&H. I bought it to hunt buffalo in Zambia a few years back. My only kills with it have benn a buffalo , hyena and a puku. Its a fun gun to shoot off of shooting sticks and very accurate with both the Barnes 270gr TS and Hornady 270gr spire points. I have a #1 in 257 Roberts that I bought back in 1980. Its been my go to gun for mule deer and antelope. #1 are fun to shoot. Ruger made the #1 in 450/400 an old British cal. Shoots 400gr bullets in the 2200fps range. I almost bought one, but my safari days may be over. They also made them in 450 nito express. Both would be good calibers for elk in the timber, but its hard to beat the 375 for versitility. I may bring it to WY this fall and shoot some doe deer and antelope with it.
Good luck on finding your #1.
