Friendly conversation please. :grin: Cartridge conversations tend to get folks all riled up, and we don't need to do that.
A couple of folks, not necessarily here, commented how impressed they were with the 325 yard first round kill on my black bear. Thanks, and I think that comes down to a couple of things: First, I practice at 300 yards regularly with my hunting rifles. Lately much of that practice has been with that particular .30-06 Rem 700. Second, the .30-06 is hardly the lumbering relic many seem to believe it to be... It actually compares fairly well to a couple of robust 7mm magnums. Let's take a look:
I largely stuck with the Nosler manual, and my own observations for this comparison. All these are with 24" barrels, very typical of hunting rifles.
According to Nosler, the .30-06 with a 165 - 168 grain bullet can be expected to reach:
2872 fps via H4350 (57.5 grains)
2909 fps via RL-17
3002 fps via RL-22 (63 grains)
BTW - Hodgdon also has several .30-06 loads in excess of 2900 fps with 165 gr bullets. Including a max of 59 grains of H4350, which is what I'm running in my Rem 700.
The good old 7mm Rem mag - a really nice cartridge which I hunted with for several years - is considered a "high velocity" cartridge, with a lot of case capacity. And it is, but let's take a look. According to Nosler, the 7mm Rem Mag, with a 160 gr bullet:
3058 fps via 63 grains of RL-22! (note the max charge of 63 grains and 3002 fps in the .30-06)
3066 fps via RL-25, a thoroughly modern powder
3077 fps via MAGPRO - which I must admit, I've never used
The up-to-date 7mm WSM attempts to keep up with the 7mm Rem mag as follows:
2927 fps via Viht N560
2954 fps via HUNTER (a powder I happen to like for my .30-06 and 180's)
3065 fps via MAGPRO
So... I'm seeing similar powder charges, and similar velocities, with similar bullet weights among the three cartridges...
Now the .30 cal bullets have an inferior BC to be sure:
.30 cal 165 gr Ballistic Tip or AccuBond is shown as .475 BC
.30 cal 165 gr Partition is shown as .410 BC
.284" 160 gr AccuBond is shown as .531 BC (dang, that's GOOD!)
.284" 160 gr Partition is shown as .475 BC (sound familiar?)
In my experience high BC numbers play a strong role in longer range shooting. Shooting which I simply don't do at game animals. I'm confident at 300 yards, if I can steady the rifle. 400 yards on a really good day, with a very steady rest. And ya, the NRA calls me a "long range high master" so I do know a thing or to about actual long range shooting. I'm just not comfortable doing it anymore with game animals. That's a different subject, but worth a mention here. Point is, at ranges I consider "normal" - out to 300 yards or a bit more - BC isn't that big a deal.
I'm not trying to say the ancient .30-06 matches or beats the vaunted "high velocity" 7mm magnums, but... It's not all that far behind either. I submit that if you can cleanly take game at 300 yards with your 7mm magnum, you can also do so with a .30-06, and if all you've got is a .30-06, there really isn't any need to go purchase a 7mm magnum... Just not all that much difference in the field.
