his buddy. His buddy asked if e had the 300 PRC, Hornady's new screamer. The know it all told his buddy that the 6.5 Creedmoor shot as flat as the 300 PRC. so we pulled out a 300 PRC and the 6.5 CM and the 300 is about twice the size of the 6.5. And ballistics showed a LOT of difference. So they left with Mr. know it all mumbling bad things about my Mother.

Anyway this brought up a question. Which is more powerful, the age old 300 Win Mag or the 300 PRC or the 30 Nosler. Got an opinion? So we googled each one. The 300 PRC is 2.556" which is .025 longer than the 300 Win Mag and 50 FPS faster . The 30 Nosler is EXACTLY the same as the 300 PRC in length, diameter, case capacity etc which for all practical purposes is EXACTLY the same as the 300 Win Mag. The 30 Nosler is 75 fps faster than the 300 PRC which is 50 FPS faster than the 300 Win Mag. So now that you are completely confused I guess we can say
nothing is really new these days.

That's a true story and has been a long time...

So many old ideas with new names. Luckily, I'm still stuck Pre-1900. I'll be a while catching up.

I have a .300 win mag that Gary slicked up for me some years ago, I used 180 grain berger bullets and got a 6x6 elk at Whittington back then. I am happy with what I have. It outshot the 300 Weatherby magnum I brought with me at the time. I also have a peculiar weatherby 270 magnum rifle, it is superbly accurate, and I love it! Sometimes I question whether I should get this or that new rifle, but some of my old timers are OK.

Smiled at your comment for it brings back very fond memories of a friend who saved & saved and after a few years ordered a 26" .257 Weatherby Magnum. Came adorned with an extra fancy piece of wood, a truly magnificent trigger and a one-in-a-thousand barrel. First 3-rounds at 25 yards were a single hole. Again at 100 yards! Well under a quarter-of-an-inch at 200, measured by some bench rest buddies. This continued to ranges you'd call us liars about! Plus the chrono was always higher than it was supposed to be. The kicker - it was factory ammo (Norma I believe)ยก! Expensive but damn!! Too damn pretty for the field but with us it went, albeit with care. Let's just say the local coyotes paid a stiff price as two of us had .17 Remingtons and when we ran out of reach (infernal wind never stops), he took over with devastating results in comparison to our pin-pricks...

What length barrels were they tested in?

this was just a short list of the 3 cartridges specs. Google

didn't go into specifics on barrel length. The 300 PRC had a 210 grain bullet, the 30 Nosler a 212 grain bullet and the 300 Win Mag a 210 grain bullet. We did find a mix up of numbers in one paragraph where they mentioned the 30 Nosler was .300" longer than the 300 PRC, so we measured them and they were for all practical purposes the same. They were both about .035 longer than the 300 Win Mag. So any in depth info is totally lacking here. We did notice a definite partiality by the gun writers to whatever cartridge they were writing up. They made a very small difference into a drastic difference in power. Typical.

Now before anyone gets all hot and bothered about this we simply googled the basic specs and listed them. We did not shoot any of the 3 cartridges nor did we check downrange ballistics. It was just a little fun test to see which one had the most potential for power and again for all practical purposes they were all 3 identical, give or take 75 fps. There isn't an animal in the world that could tell the difference.

I think there was a gun writer that said something like

The practical differences in the 300 magnums you could fit under your fingernail.

I've seen a "Fast" or "Slow" barrel make that difference..

on several hunts including this last African hunt where she took an Eland, and a Kudu. Both extra large animals. Her Cape Buffalo was taken with her 458 that I built for her.

308 or 30-06 would more than likely get the nod. Would probably go with 300 Win on the magnum side.
Good luck finding ammo for some those super duper magnums, those younger might as well get the 30-378 Wby and prepare to drop alot of cash!

Haven't met a deer that the old 30-30 can't handle
