Well, no offence intended to anyone, but, if you know many highly experienced "western" Canadian hunters, you will find that many of them TRIED the 6mms and a few the "Bob" and you do not see many of these still using these rounds.
That is, of course, due in some measure to the usual purchase of a few rifles to be used on ALL legal big game species and very few will choose a .243Win. in this role over a .270Win. where the same rifle will be used on both deer and elk.
I frequently read comments on the very few "gun" sites that I ever visit by various posters about killing "hundreds" of game animals or, a real favourite, "truckloads" of elk, moose and so forth. I tend to view such comments in much the same light that I do the assurances of politicians about pretty much any aspect of life...........
YES, with a GOOD bullet, a 6mm WILL do the business on deer and even elk/moose and the 25s are, IMHO, a bit better, especially the excellent .26-06 and/or the .257 Bee, one of the three "Roy" cartridges which I have never fires.
BUT, and this is merely a query as I realize that the TSX type of bullet in a .243Win. WILL whack a baited deer from a close-range stand, I do not "get" WHY anyone would choose a cartridge/bullet for an expensive and perhaps "once in a lifetime" hunt that is marginal in all-around uses in the area being hunted.
A .270Win. or .280Rem. will do anything that the .243Win. can do in this situation and a lot more "all-around" and I have found these to be ideal for deer killing here in BC. Based on my field experience with the Alberta Dept. of Environment, 1990-1993, I think that this would hold true there or in the other "Prairie Provinces" as well.
JMHO, I no longer own a 6mm of any type or a .257" cal. but, were I younger, I would definitely have one of each, a 6mm Rem. and a .25-06, built on those HVA actions sold cheaply by "Tradex" and with STS bbls. by Ted Gaillard. With my Ruger MKII lam. stock, sporter weight .220Swift, these would give me the battery for winter predator culling that I hope to do.
