To me, efficiency is the best ratio of pressure to velocity.
If you can get more velocity with less pressure, the load/cartridge is more efficient.
Comparing a so-called Magnum to a so-called Standard cartridge, if the larger Magnum case will get you more velocity, and a flatter trajectory at the SAME pressure, it is more efficient.
The Magnum cartridge does burn more powder, but what do you want? A safe load, with greater performance, or an economical one?
Economy is a desirable thing too, but if you need/want greater performance than 280 Remington, the 7mm Mag. will provide it at the same pressure level as a 280. Or, 280 performance without half trying.
You may prefer the 280 for some other good reasons, including economy, but �efficiency� the same thing as economy, is it?

How's that 250 Classic doing John? Inquiring (nosy?) minds need to know.

Haven't even had a chance to shoot it. As a matter of fact, have only had one brief range session in the past month, because it's been so cold. Where the heck is global warming when you need it?

I saw elsewhere you'd been out shooting the 300 H&H. Did you happen to take out the little 250?

No, unfortunately not. We got a brief break in the winter weather (up to 20 degrees, with no wind!) today, so I made a quick trip to the range and only had time to do some necessary testing. One of the tests was the first range time with the new Leica scope.
But we usually get some nicer weather in February and the .250 will be one of the ones up. I also have acquired a couple of other 700 Classics in recent months, a .221 Fireball and a .350 Rem. Magnum, and they need a workout too. Also just got in another Ruger No. 1, a .450/.400. So little time, so many rifles!

John, After your hunt with Bill Wilson last weekend I'll bet you have a NEW addition to efficient cartridges. The 6.8X43, better known as the 6.8SPC. A VERY effecient cartridge in a nice light easy to handle package. I can't wait to see what you have to say about it, it's almost like a 'little Bob' (257 Roberts).

Red Monkey,
I was VERY impressed! The 6.8 puts even big pigs down right now with the correct bullet. Am thinking about getting a 6.8 SPC upper for my own AR.

John, I knew you would like the 6.8!! I haven't gotten to try any of the new 95 gr. Barnes yet but I really like the 110 gr. Accubonds. I took two deer this year with the 110's, one at 175 yds and the other at 125. Both shots were pass throughs, which I like. As Elmer Keith said, "Two holes let out lots of blood and in lots of air." Works for me! I'm using 29.7 gr. of 10X in SSA small rifle brass under the 110's. I have a couple of hundred 100 AB to test but I kinda like the extra weight and higher BC of the 110's. I can't decide if I want to take my 6.8 or my .308 if I'm drawn for a Montana combo deer license for next year. The area we hunt is river bottom so shots will be withen 200 yds. max so I'm leaning toward the 6.8. It would be great to take a mulie with my 6.8!! I miss your input at "Rifle" and "Handloader". Hal

The guy I hunted with in Texas has both pigs and whitetails on his ranch, and it's in northeast Texas so the deer are somewhat bigger-bodied than further south. He likes the AccuBonds for deer but prefer the TSX's for pigs.
10x is evidently THE powder for heavier bullets in the 6.8.
In a few months my articles will be appearing again in the Wolfe magazines. We reached a new agreement a couple of weeks ago.

Now that's some good news, guess I'll renew after all, Phil S is the only reason I'm still subscribed. --- Mel

John, Great news that you are back at Wolfe. It is certainly good for them. I suspect they realized they had made a big mistake because of lost subscribers when you left.
But it is especially good for us. We get to read more of your articles.

I just bought a Rem. 700 Classic in .250 and am anxious to wring it out....
Had one a few years back. Four of us used to get together at the club on Wednesday after work and shoot offhand for score @100yards.Low man bought the sodas. It shot 75gr.Sierras HPs like crazy but 100s and up was a waste of powder. Barrel twist I suspect.

100 grain bullets shouldn't have been a problem. My 700 Classic makes small groups with 100 grain Hornady Interlocks, Sierra Game Kings and Nosler Ballistic Tips.

Ifelt the same way, however the rifle had other plans. Coulda been me but that would have tarnished my image.

JB, that is good news with respect to Wolfe. I canceled when you left. Which one will you be in or will it be RIFLE and...?

All three, at least some of the time. After personally experiencing political justice in the business sector here, I am truely glad to see that integrity and competence has risen to the top where it belongs. Congratulations to you John. JW
