Thank You Donovan for those very kind words! I appreciate it! And as you know, I have consulted you on many occasions because I value you opinions greatly!!
Load development at distance
- Thread starter 4xforfun
- Start date
I shoot five shot groups instead of 3. Shooting them at 100. When I find my best group I load 5 more at the range using my wilson hand dies. If that 5 does well I'll load 5 more and shoot 600. I've never had a 100 yard load fall apart at 600.

Sort to speak, what do you do if the accuracy level is good, but not good enough to win?
Do you go back to 100 and fine tune it there?
For me it's not so much that they fall apart (but have seen that), more unable to make them better or fine tune them to perform better for the intended distance. Repeatedly have seen, the smallest group tune at 100, not to be at 600/1000. Often seen a 100yd tune that has vertical to it, have the least vertical at 600/1000.

Your statements have a lot of merit, looking back my 2 favorite LR rifles had loads developed at 100. Also looking back, they had more vertical stringing though. I find it way easier to eliminate vertical dispersion if developing at distance. Plus, I can shoot a group at 500 way easier than 100, I'm a 100 yard tard.
What size groups are you shooting at 600? I am not talking one lucky group but consistant groups. Matt
I'm looking for a quarter inch or less at 100 yards and less than 3" at 600. I've just shot club matches bench and f class but to win here most days you just need to be close to 2" at 600. Might add we are on the gulf coast here with strong and changing winds so 600 yard groups are harder than 100.
Since a few different ideas have popped up reguarding groups at 600/1000, I am going to run some tests this summer. I will set up my targets at both 750 and 1000. I will shoot sighters and a group at 750 and then immidiatly swing over to my 1k target and do the same. I'll probably let things cool down a bit and shoot it again .......backwards....1000 and then 750. A few days of testing should shed some light, and it will be good practice for an old guy like me.
Should be fun,

Not to disagree with anything said here, I have been shooting a new 284 Bartlein barrell, 180vlds in F Class. I tuned at 200m initially and then finished final load at 400m,loads look good on paper and this rifle has shot extremely well for me in F Class from 300m to 900m, beating some of my States best along the way. I recently purchase a labradar and ran 15 shots past it and was very surprised to see an ES of 50fps, shot a 700m comp that day for a 60.5x and 58.3x only dropping 2 points for the day..
maybe the labradar wasn’t set up correctly I’m not sure but 50es seemed very high for a load that holds tight vertical From 300m to 900m all year round ?? Any ideas??
All i can say is i hate load testing at 100m. You just dont get enough information for my liking
I had to do this recently as the conditions were crap here and I needed a load for state shoot.. at 100m i had a heap of all touching groups and picked a load then did seating at 100m and had a 4 seating depths that looked good. . Picked one and used it at 500m for state shoot and 2 to 3 inches of vert got my lowest scores in over 12 months
Redid test from scratch after states at 300m as got a better day and found i was 0.2 gr over the node i picked at 100m
Redid seating and it liked a jump better than jam (which was easier to see at 300m than 100m)
Shot at 500m and boom under inch vert .. now i have changed from 105gr hybrids and need to do everything again haha.
But the longer the testing better imo

I do not understand the scoring for "Euro Scoring">> However, let me see if I am extrapolating it correctly. If I am, I MAY have an answer to your question.. If I am reading it correctly, in America you would have got a 200-5X and a 198-3x? If this is correct, your answer may be that with those HIGH e.s.s, you could keep the shots inside the "American 10 Ring" but had a difficult time keeping it in the "X" ring.. If my reading your score is correct, then the "vertical" kept your "X" count low. However, I have NO IDEA how your scoring works, so I may be W-A-Y off..
Sorry I’ll clarify a little, it’s 10 shots for score, X=6 points, V=6 points, the V is equivalent to American 10 ring and our 5 ring is equivalent to American 9 ring. The two 5s I shot were waterline which cost me two points. So I think the score I shot using your scoring system would be 100-5x and 98-3x. So you think that score could reflect a high es using your score system? from memory most my shots in v or 10 ring were close enough to waterline that if I’d centered them could have been Xs. hense my wondering about a 50fps es..
Maybe I’ll try and improve the es to see if x count improves.. cheers for your time and input.
Wish I could be of some help I do most of my tune at 300yds thats the best I have to offer..
I also think that with a 600 yard compass it will be difficult to adjust to 1000 yards. I would first try 750 yards, and from this I could already provide for a load of 1000 yards
I’ve done load development at 200m for 400m and 500m Competition and it’s been fine..
Rushty,
I would not rush to judgment on the 50 ES. before I confirmed it with another chrono. I personally am not convinced the Lab Radar are all they claim to be. May save you some grief with a load that seems to shoot well for you.

My judgement is reserved at the moment on the ES from the Lab and in general..Rushty,

The average speed the Lab gave me was spot on with my ballistic calculators and targets out to 900m.
It’s a work in progress thing for now.
Cheers Rushty
