I wish I could keep all my groups under 5" for 5-shots @ 1k-Don't we all???
1K shooting is about conditions, conditions, conditions for me.
Best 5-shot groups with specialty pistols @ 1K matches: 5.25" with a MOA Maximum, 15" barrel and a external hammer (talk about slow lock time), and 3.871 with a specialty pistol set-up for BR shooting. I shoot about 1 1K match per year.
I can do better in good conditions when shooting only 3-shots for sure.
Just because I can shoot a .25 MOA group at 100 does not mean I can 2.50" group at 1K-If it was only that easy
Shot placement on the target is very important for me.
Two and three shot groups on "proven guns" are going to give me the realistic capability of myself and my weapon at distance. More shooting is going to have more to do with my wind reading skills than anything else.
I have been shooting a 7mm Dakota recently (One of Len's lightweight Long Range Rifles). Field shooting with a Atlas bipod and a field bag just this week, I put 2 shots in a 1.75" at 1K and I was shooting right-handed (I'm a lefty). It was no surprise when later on Len put two shots at 950 yards that measured 1.5". It has consistently shot sub half MOA when conditions were good from two different shooters. This is what I expect from a custom rig.
I have shot rifles more recently in the last couple of years. This year I decided sort of at the last minute to get a F-Class rifle built. My first two matches was at the F-Class Nationals and World just south of Raton NM. Also my first time to compete with a rifle! This is not BR-You cannot rapid fire your shots down range like BR. I shot F-Open for individual and then was invited to shoot TR for the team match.
My second morning I shot a 150-6X. We had good conditions!
What does that mean?
The "X" ring at 1000 yards is 5" and the 10 ring is 10". Out of those 15 shots, 6 were 5" or under and the other 9 were 10" or under (it is a score match). When you add my sighters, of which I had 6, I had three 10's and 3X's, with my first cold bore shot being an "X". 21 shots 10" or under, with 9 of them 5" or under.
To put my first within 2.5" of the center is always pleasing at 1K.
Mac's Gunworks (South of Gillette) built that rig.
This is what I expect in terms of accuracy of my rigs.
