With the gongs set at known distances, consistent hits can be made - and quite easily. My current hunting rifle has sights from 100 to 200METERS with heavy loads. The accuracy is all that is needed to hit moose in the ribs - every shot with a rest at the 200yard range.
The power/velocity generated by the 165gr. 2f charge is sufficient for the 480gr. pure lead or 466gr. WW round ball to do it's 'stuff' - out to that range.
However, since moose can easily be called in for a 50 to 100yard shot (or stalked that closely), the 200 leaf has never been raised for them. I prefer to "stagger" them at close range - and it does.
The 200 yard/meter has been raised only for plinking to that range. I use a laser range finder so I know what the range is BEFORE the shot & use the appropriate leaf. I also know how to hold for a 300 meter shot, as I used to have a leaf for that range too - with the current 200yard wide V, I hold level with the top 'wings', bead in the centre of the gong and it gets rung.
We used to have a 300 meter gong (about 328yard) set up for your rendezvous here, back in the 80's. My hunting rifle has been fired at that gong by at least 4 other club members - it never missed. None of them wanted to shoot it again. I don't know why - it is very accurate to that range. I even placed middle of the pack in a BP Ctg. event at Helfely Creek back in about 2008, with it. They only shot to 250yards & my best shooting was at 175 and 250. Had I not screwed up on the chickens at 100yards (yeah- dumb), I might have been in the running for prizes.
Do not discount the larger calibers for long range accuracy. I was at the range when Taylor shot a 2 1/2", 5 shot group at 200yards with his open sighted .62 Hawken. He was also there when I did likewise with my .69 - it was the same day. Prior to that, my best group was 6 shots into 3 1/2" high X 1 1/4" wide group. He was also there that day as well. We were practicing for the 200yard ALR match that only Taylor and I joined George in entering.
My .69 won that event - those years ago, which prompted Taylor to build the Hawken. We've not shot the even since -
?
Even though my combined position group was much larger than I wanted, every one of those shots, 5 sitting and 5 offhand would have been through the lungs of a moose at that range.
It does kick a bit. But the down-range rewards make a bit of recoil worth it - besides you do not feel it when shooting at game. Taylor's 200 yard load in the .62, is 127/8gr. 2F. Any more than that & it gets rough on the shoulder/arm joint with the rounded, narrow Hawken butt plate.
