Gentlemen
Lately I watched an interesting part from the local sportschannel on TV.
It was about longrange shooting (1000 meters)
It was held in Germany, I saw that Ruger #1 was used alot with other single shot rifles..
It was not shown what calibers used, the only thing I could see, it was medium bore size catridges..

Any suggestions what caliber could be a good 1000 meter caliber? Some of the cartridges used was rimmed.

As long as the bullet remains supersonic at the target, there are any number of cartridge choices.
If the caliber has a selection of high BC bullets available, that's a good thing.
Higher velocities aid in reducing wind drift (as do the high BC bullets).
In 30 cal (7.62) choices start at 30-06 and goes up from there (300H&H has won it's share of trophies, as has the 300WinMag), limited by the shooters recoil tolerance level.

it's possible the match you watched was relegated to only single shots.....I'd certainly not use a Ruger #1 in this event. Actually I'd be looking to Savage and a custom barreled .300 RUM or .338 RUM for precision 1000 yard shooting.

lets hear it from the 1000 yard bunch out there.

The 1000 yd "small bore" sport in this country is centered in central Pennsylvania. The cartridges have evolved a bit over the years as in most sports; 30 years ago it was the 300 Wby or a 7mm or 6.5 based on that case or some other magnum. In modern times the 6.5 x 284 has become popular as has the 22-250, both with heavy-for-caliber bullets. I think they're up to 80 or 88 gr in the 22-250.

Another interesting factoid; velocity variation is critical due to vertical stringing. At 100, 200 or 300 yds standard deviation is only an indicator of potential accuracy. At 600 it begins to show a little but at 1000 it is as important as the MOA capability of the rifle. Brass is actually shot to determine its's potential, not just weighed and mic'ed. Wind doping is a bit diferent too. You're looking for a "gap" to fire as many rounds as possible rather than doping for each shot. Best case you get a window big enough for 10 straight quick shots rather than 5 two shot windows that seem the same. Of course that may have changed in the last 20 years; I'm a little out of it now.

8X75R, .30/'06, .300/.378 Weatherby, 6.5mm Weatherby/Wright Hoyer, 6.5X.284, (any medium to HV cartridge for which excellent long-range match bullets are made......)

Good info here, and the last I heard, last year I believe, yet another world record, a 5-shot (light gun) group was fired that measured under 2". Yet another record group fired by the .300 Win Mag. I may be mistaken but I believe the .300 Winny may still be the all time winningest round at 1000.
