group size

When I have a rifle tuned for a match whether it’s 300 meters, 600 yards or 1,000 yards it will always shoot in the ones or maybe twos at 100. The interesting thing is just because you have a load tuned at 100 does not mean it will group at the longer distances. Load development needs to be done at the expected distance you will be shooting if at all possible.

I agree with this statement but if you don’t have access to a 600 or 1000 yd range you have to work with what you’ve got, I am blessed to have a 300 yd range and I do my tuning there, my rule of thumb is if I can get it to shoot .750 or better at 300 it will shoot at 600 if I do my part.
 
If your 3 shot group doesn’t look like this at 100 yds- no need to try to get a small group at 300yds or 600yds- it’ll only open up at further distances-
Weather comes into play,( wind reading, temp, humidity, powder sensitivity), then try put it all together- your bench manners come into play-( not keeping eye in the scope, fumbling rds, etc…

I’m still learning to speak wind myself, just happened there wasn’t much the other morning..

This is generally what I have seen as well. .75 or lower will generally shoot .2 or better at 600.

Wow!
Look at this from the Hog roast teen aggs all the way to 9th place
Impressive indeed. At two hundred yards a .15 moa is a .30 group. At 300 it would be .45. As I recall .45 inch agg is the record at 300 and has been for years.

Getting consistent groups under .2 at 100 is one thing doing it with a ppc, but quite another doing it with a 6bra or dasher. To be competitive at 100/200 it is required with a ppc. Even with a gun and shooter capable of shooting .15, conditions are still the wild card.

On the other hand, I would be proud to shoot any caliber that consistently gave me under .2 moa at 300. And .15 at 100 does not mean the gun will be shooting .45 at 300 or .9 at 600. As stated, often time the tune at 100 does not hold like that.

The last thing I will add is that “tune” means different things to different people. When some of the seasoned guys talk about being “in tune”, one would be wise to look behind what they are saying to figure out what they are really talking about and how they get there. Their standard for “in tune” is different and a high bar to hurdle.

My previous comments were based on Speedy Gonzales video. Hard to believe it's common to shoot aggs in the 1's. How much money do you think it cost for everything that's on the bench when your competing at a top level? rifle, scope, front rest, bag total cost? What's the value of everything you own that's shooting related. Some guys have a Bridgeport and a quality lathe. Several full race rifles. What does a full race rifle cost put together by a top gunsmith?

I’m just commenting based on my own experience

All the stuff mentioned above is probably less than a new bass boat or even a used one a couple years old
