RE: Whetherby .30 378
Yes if you intelligently shoot this gun you will see longer barrel life. That means waiting at least 5 minutes between shots on a relatively cool day so the barrel doesn't become too hot and longer on those hot days.
You fire three consecutive rounds out of a 30-378 and the barrel will be too hot for you to hold it.
So you get aproximately 2000 rounds out of a barrel according to Weatherby if you shoot it intelligently at the range every time. If a person practices enough to get proficient with such a specialized cartridge to be able to take full advantage of its capabilites then he will be at the range firing up a box every week or more at 500 and 600 yards. So that translates to about 2 - 2.5 years of barrel life. If he isn't at the range practicing weekly then the point of having a 30-378 is pretty much gone. Any regular ole 300 magnum or 30-06 will do everything the 30-378 will.
These comments are not intended to tell him not to purchase a 30-378. They are intended to allow him to make an intelligent and informed decision regarding the type of hunting that he does. Rather than just say "I love mine you should buy one" some of us are giving real information. This is not one of those doo all cartridges. It is one of those cartridges that require a lot of dicipline while shooting, a lot of long range practice,
Perhaps his absolute longest shot oportunity where he hunts is only 300 yards. The 30-378 isn't going to kill a deer any quicker or any deader than a .270 winchester. Perhaps he doesn't have access to a range where he can shoot at 600 yards. Etc... etc...
If a person is able to take advantage of a 30-378 then by all means get one.
Oh, and BTW..... Some of us here do in fact do this stuff professionally. So there is no reason for you to be a sarcastic smart arse.
