[QUOTE="4xforfun, post: 426291, member: 9172"] I know we are getting off topic, and I don't mean to pull a hyjack, but... My thoughts about going to a 7mm rum or improved version vs a 338 rum or Edge. Now, these thoughts may be WAY off........and...this is for deer sized game, not elk/moose. First, obviously, the energy requirments for deer are far less than that of and elk/moose/bear/ect.... My concern would be energy transnsfer.....or skock....I feel that a bullet needs to expand (mushroom) and dump the energy INSIDE the animal. So, and these are only MY thoughts, I would think VELOCITY would be a key factor.....you need the FPS to get a bullet to open up. It would be easier to keep the velocity up (using a regular .535 mag bolt face) on a VLD type 180 - 200 gr. 7mm at , say 3200- 3400 fps muzzle velocity, which would be do-able with a big 7, than a 300 SMK or berger at 2850 FPS, which would be very do-able with a rum/edge. Now, if the animals get bigger, the range goes beond, say 1500, or you can go with the bigger boltface and more horse power, then it's the 338 by a landslide!!! But, given the constraints of the .535 boltface and the energy requirements for deer, I gotta think that the BIG 7 would be great. Tell me where I am wrong. I am sure I missed something.... What would a reliable speed be for a berger/jlk/uld to open up reliably? Does this number go up with the bigger cal bullets? This is the reason I am working for MAX FPS in my 300 WBY/210 (see other thread..300 rum vs wby). I feel I need the FPS to get the bullet to open up. Now, all that being said.....I would love to get a .338 tube for my match gun and go all out and get , at the very least, an EDGE, or buy a bolt and go with either a Lapua Improved or a Chytec based round. It's just not in the cards right now. Ill have to make do with the "lowly " 300 WBY. FUN STUFF!!:D [/QUOTE]
