Home Forums Hunting & Shooting Express Rifles and Big Bores Only What Is A Big Bore??

Definition, anyone

varies depending where your at......think the Brits say above 458 cal......for here its a catch all for everything above 358

So size is different depending on where one lives. Wow math will never be the same again

Why is the 50 BMG never brought up here on the big bore.

Good question, but the 9.3 is in the big bore forum

just one of those terms that has no set designation.....think the Brits call a 416 a medium but anyone in the US would call it a big bore.....

i THINK the 50BMG aint talked about much here cause its usually a long range shooting round and not a hunting round though i know its used as such......505 Gibbs and AR-50 are both 50 cal bolt guns but the intended purpose are very different.....

Big Bore, the traditional definition first laid down by the Brits, is 45 cal and above and with the accompanying MV/ME component, ergo neither military rounds the 577/450 Martini Henry nor the 45/70 are condidered Big Bores. jorge

If it were me, I would use the definition of a legal and acceptable dangerous game caliber in most of Africa as being the bottom end so am OK with a 9.3 being talked about here. Never had one, so no dog in that fight but as an example I definately consider MY 416 Rigby a big bore, some might not, this causes me no lost sleep. As with any of the forums here if I don't like a thread or topic, I don't open it or at least don't comment. Been biting my tongue over the latest batch of Remington model 700 plastic stocked 'customs' even. Going with the idea more that if I can't say something nice, to keep my peace more oft these days.

Arbitrary. Just go with "you gotta grab 'em!"

What arky said...+++++1!

This forum is mainly visited by sportsmen, and the 50 BMG isn't really a sporting cartridge.

Wolfe Publishings book "Big Bore" is about cartridges over .308 caliber, including if memory serves one of the .311's, and definitely the 8mm's.

It is absolutely an arbitrary concept this Big Bore idea, but when you set off a 416 Rigby, you certainly feel like your in the club.

I assumed (yes I did say assume..lol) it was .400 rifle and above. I bought a .375 H & H and was told its a medium bore.

In light of today's trends this makes a bit of sense, IMHO

I tend to see the 50 BMG as the 22 Hornet of the big stuff.

But it has to be 375. Apart from minimum for African DG, it is where many gun makers seperate the rifles out. M70 for example. With Wby their 378 and up don't come in the cheaper versions of their rifles. With custom guns it is 375 where express sights become a standard. 375 is where lots of shooters start using round noses and don't get into a knot about ballistic coefficients etc.

Guess it depends who you ask.


Winchester made the "Big bore '94"

Marlin calls the 444, 45-70, 450Marlin, "Big Bore".



In the context of this forum, I believe it means African DGR.

375 and up

I also agree with the 375 and up.

As for the BMG, we have had 1 at our bear camp a time or 2 but in reality, who wants to carry it? Last time we had one at camp we were baiting for grizz. we had bait at 600yards (pred control area) and no one wanted to shoot cuz we all wanted to watch the impact.

Thanks for the input about the 50 BMG I did not meen to take the discussion over but I understand about the big bores a little more now.

It would be pretty hard for anyone but a Ben Hur to shoulder the damb things. They are not portable friendly as are all of the big bores that are being talked about. The 50 BMG is a set up and waight gun not a tracking one.

Thanks for the input again
