300 RUM

love mine. Had it accurized and muzzle break put on. Shot nice Colorado buck last year at 595yds. Tack driver. Loading 200 gr Barnes TTX to go on Alaska Brown Bear hunt this fall. Should be great!
Really nice caliber.  Have shot 2 elk and 1 deer with mine and all have dropped in their tracks.  Can be expensive to shoot though.  At one time I paid $75 for a box of 20.  Now I think they're around $60 - $65.
I dropped a deer in his tracks with mine.  I load 200 accubonds but want to try the barnes X. 
Peppy, is it worth the effort and added noise to add a compensator?  I was considering adding one because I have one on my 7mm.
