Medium calibers

longwinters · Dec 5, 2007

Its funny how things seem to change. I would have always thought that the 270, 280, 06 etc... were the "medium calibers" but I guess the new mediums start with 300 win, 338 etc... according to John Barsness (and I guess he would know if anyone would). So what does that make the 270-30-06 etc...? The 30-30's of old?

I thought they were called 300 magnum and 338 magnum.
Somebody better call SAAMI and tell them to change them to 300 medium and 338 medium.

long...my "medium" 270 Win has accounted for more meat-n-the-freezer than all my others combined. Guess I'll stick with medium.....However, those LARGE GUNS sure are fun to shoot...

This is kind of how I've always looked at it. Calibers .177-.264 are small bores, .277-.358 are medium bores, and .366 and up are large bores. As far as cartridges go you have Standard, Magnum (H&H, Win, & Rem), and everything else bigger :shock: .

That might be what Barsness was talking about them being "medium calibers". With the RUM, Lapua, STW and Lazzeroni taking over as the large. Compared to these newer Magnum rifles the 7mm Rem, .300 Win, and .338 Win would seem like medium powered cartridges.

JB's article was interesting, and he based his selection of cartridges ("Medium Mediums") on a division originally described by John "Pondoro" Taylor in his book African Rifles and Cartridges from 1948.

Taylor first described the older black powder cartridges and classed them, then moved on to the more modern. His medium bore rifles were those between .318" caliber and .375" caliber.

JB also added energy limits to produce the medium medium label.

And Teddy Roosevelt thought the 30-30 was a"wonderful rifle" for Pronghorn because of its flat trajectory and wind bucking ability. :lol: :lol: Marketing boys Marketing!!! :wink: CL
