Is there inherent accuracy?

I shoot 600/1000 yard F-Class matches. I use a custom Savage with a 30" heavy barrel in .260 Ackley Improved. I use a 139gr Lapua Scenar BTHP bullet with 42gr H4350. This gets me 2860fps and is the most accurate velocity for this rifle/bullet. It uses 11.5 moa of elevation at 600 yards and 28 moa at 1000 yards.

My next project is to screw on a 28" barrel chambered in 7WSM and run the 175gr Sierra MatchKings.

Is there inherent accuracy?

At one point, the 300 H&H won the 1000 yard contest (long time ago, and I can't remember the year or the man), and it became the new hot shot. It's a long case, but obviously that was years ago. I'm with Don here in that it's more likely what bullet was used by the last guy that won.

Some savants can shoot similar groups with 45/70's. In some extremes there are innate differences (i.e. a boat tail is more accurate than a hollow point), but in my opinion, it is the rifle and the shooter that make most of the difference. Then again, I'm not a long distance guy, at least in terms of hunting.

Also, Im sure some bullet types and cals. are more accurate with certain wind conditions... heavier faster bullets are less effected than lighter slower bullets etc. But, everyone knows that.

The .300 H&H was the popular long range cartridge in 1940's-50's. It was eventually topped by the .300 win Mag and now the 6.5-284 is becoming the most common although there is currently a swing towards the heavyweight 7mm's.

I believe that the 300H&H of the 40's and 50's was not much more, if any, than todays 30-06. Gotta think too, that these cartriges being popular is a fad thing. Seems like they just keep bouncing around.

A little off topic, but on the same point... snipers use, or at least use to, standard ole 308's. There's no super short magnumized anything there. You got to think those guys need something to rely on. In vietnam and WWII, a lot of those guys were using -06's. I really do think it is the man, first and foremost, and then the rifle and bullet type that determine accuracy.

On another thread, someone claimed that the short magnums are innately more accurate than the longer cases I think some weatherby and 375 H&H owners might have something to say about that. I'd just need empirical data to believe this,,, why aren't snipers or competitors using them if they are so much more accurate? Think Think Think

Snipers use the 7.62mm NATO (.308 Win) because it is what they get issued. It was once the primary combat cartridge. It is still used as a machine gun chambering. It was untilized as a sniper round because it was already in service and the military likes to stick with things that are already in the system. Most sniper engagements take place at under 500 yards where the .308 performs well. Police engagements take place under 200 yards in most cases.

For farther out shots, the military has experimented with using the .300 Win Mag. Most European countries are now using the .338 Lapua as their standard sniper round.

As for match shooting short mags, it is gaining popularity. My barrel for next match season is a 7mm WSM.

Yeah, snipers also shoot 50 cals too. My point was, the cops and the military wouldn't be shooting 308's still if they weren't accurate.

Some people probably do prefer the short mags during competition and otherwise, but that doesn't prove an inherint advantage in accuracy. I don't know if they do or don't shoot straighter. I'm just saying, I've never seen any proof that short mags are innately more accurate then any other round. Like Boddington's article said, there just isn't anything that significantly advantageous about them. I'll trust that he knows what he's talking about, but if someone can find me clear cut evidence that short mags are more accurate, then I'd be happy to agree.
