When I'm deciding on my 600 yard load or beyond, I often end up with 2 choices in the end. At that point ,our match strings are usually 22 shots...
I"ve done a few months of test shooting 11, and then 11, and plotting, and I won't even look at teh data for info for a few months, then go compare all the plots to see which one is clearly better day in and day out...
It takes a lot of shots to be totally sure, or as sure as you'll ever be.

rost, Ebonics aside. Not to hard to tell around here who gets the most out of there equipment. True story. I shoot 1000 yard BR Silhouette. 10 crows at 850. 10 woodchucls at 900. 10 bobcats at 950. 10 cototes at 1000. A possible 40 for score.36 is the record and it has been done twice.Not by me. My heavy 17 pound rifle is a 300 RSAUM.I run 210g Berger LRBTs at 2800fps.I typically shoot in the mid to high 20s. I had to switch to a new lot of bullets. Left my seater die alone and never checked the loaded rounds against my barrel stub. Went to the match and shot a 9.
It didn't take to long to find out what the problem was after I got home. Checked the loaded rounds against the barrel stub. I was running the 210g LRBT .013 into the lands. Yes the new batch of bullets were pretty different from the old batch.Different by .013.The rifle has never shot in the lands.And only hitting 9 targets that day proved it. Not a mistake I will be making again. Berger bullets from lot to lot can be totally different. To prove to myself where I needed to be I ran a seating ladder.I shot 4 shot groups at 500 yards from kissing(whatever ebonic BS that means) to .025 off the lands in .005 increments.Took some long seated rounds along and seated them with a small arbor press at the range,shooting the best two seating depths against one another. Last match of the year back in October I shot a 29. The crows at 850 are a nightmare if you dont have every bit of vertical dialed out of your load.
You guys fail to realize, you are all trying to get to the same place...an accurate load. Less vertical spread my show up on a ladder test, but it also shows up on the chrony.

Different powders have different burning rates which shoot at different speeds. also the bigger the case the bigger the difference between shots through a chrono. It may show on a chrono but like the gentlemen said a chrono just shows speed. a speed at which you can use to build your dope for long range "hunting". after you waist your time of "ladder testing".

Years ago I had the bottom of a ladder slip out from under me. I ALWAYS do the ladder test now!

Interesting.
I'd like to hear more of how y'all do it.
