Well, it's obvious you've made up your mind, but the reality is that you CAN do what a .300 H&H mag does with a .260. My original point had more to do with the .308 being a ballistic twin of the .30-06, but comparisons across calibers are informative too. The typical .300 H&H factory load is a 180gr premium bullet with a velocity of between 2800 and 2950 and a G1 BC between 0.45 and 0.5. Top SAAMI hunting load in the .260 is a 160gr Weldcore at 2750 with a BC of just over 0.5. The H&H has a bit of an advantage in velocity and cross section, but a minor disadvantage in BC and a HUGE disadvantage in sectional density and thus penetration. The .260 will keep that bullet in the manufacturer's velocity window out past 400y at sealevel, farther at altitude. There aren't a whole heck of a lot of ethical shots that come up past that. And I know from substantial experience that 160gr .264 premiums give better performance on elk+ sized game than 180gr .308s do.

Now, lest someone get huffy, yes I hot-rodded the .260 and left the .300 H&H at it's usual performance level. The point here is that the difference between careful loading and generic loadings is bigger than the differences between cartridges.


The point here is that you admit to hot-rodding the cartridge of your choice to make it look better than the other cartridge. That's the kind of thing children, liars and cheats do, not adults wishing to have an honest, rational discussion.

You claim a .260 with a 160g Weldcore (B.C. .509, S.D. 328) at 2750fps is equal to a .300H&H. Really? Hodgdon lists a 212g ELD (B.C. .673, S.D. .319) at 2750fps. That is a "huge" advantage in B.C. and a very minor disadvantage in S.D for the .300 H&H.

Here's how your "hot-rodded" .260 load and a book .300H&H load compare:
Code
At the muzzle:
.260 Rem = 2750fps, 2351fpe
.300HH   = 2750fps, 3560fpe

At 100 yards:
.260 Rem = 2607fps, 2112fpe
.300HH   = 2621fps, 3233fpe


At 200 yards:
.260 Rem = 2468fps, 1893fpe
.300HH   = 2495fps, 2930fpe

At 300 yards:
.260 Rem = 2333fps, 1692fpe
.300HH   = 2373fps, 2650fpe

At 400 yards
.260 Rem = 2203fps, 1508fpe
.300HH   = 2254fps, 2391fpe

At 500 yards:
.260 Rem = 2076fps, 1340fpe
.300HH   = 2139fps, 2153fpe

At 600 yards:
.260 Rem = 1954fps, 1187fpe
.300HH   = 2026fps, 1933fpe


Granted that bullet velocity, drops and drift are about the same (the advantage goes to the .300H&H), the ,300H&H carries far more energy to the target than the .260 can dream of. In fact, the muzzle energy of the .260 is equal to the .300 H&H at about 415 yards.

At 400 yards, your self-imposed limit for most "ethical shots", the .300 H&H book load delivers 59% more energy than your "hot-rodded" .260 load.

First you claimed a .308 is the equal of a .30-06, but both factory and book loads show that is not the case. You claim QuickLOAD is infallible but even QuickLOAD fails to support your claim. Now you claim a "hot-rodded" .260 Rem is equal to the .300H&H but the first book load I looked at shows the .260 falls far short.

If someone knocks on your door, I suggest you run - it might be the mem in white coats.

No, I'm not a Ruger bigot - just an unabashed fan of their revolvers, M77's and #1's.

A good .30-06 is a 99% solution.
