I have OK experience shooting my .177 at 92 yards and get OK groups. this pea caliber ( 13 gr Zan slugs ) are of course weather fussy, but i use 2" splatter targets and can generally hold my shots on that even in the wind ( not super high wind of course )
My favorite " game " is one i call annihilate the red base, meaning take out the red dot on the target, it is not as easy as it sound like even when the rifle are in the Zone, so the 2" target most often end up looking like Swiss cheese before the fire mission are complete.
1 perfect shot though, and right on, and the red base will be gone, well at least as far as i can tell in my 40 X scope.
My #2 most fun "game" is called, kill the enemy spy, this is flies landing on my paper ( i often douse backing in soda )
This mean my entire piece of backing cardboard end up looking like Swiss cheese, or at least as if some really not that good shooter have been shooting.
So far i have just managed to kill 1 spy / fly at the 86 M / 92 yards MAX distance.
Some times you drill a hole just as large as the fly and only a few mm from it, and the damn thing dont even take off, but most often they will relocate.
I shoot a Maverick with a 700 mm barrel, in the standard liner the 13 gr Zans are a little less accurate but not a whole lot, heavier stuff absolutely do not work in this barrel.
With the 700 mm Heavy liner the 13 gr Zan i generally shoot better, still not able to shoot heavier stuff in this, but some fellow Danish .177 shooters have some luck with 16gr Zans.
For a while i shot my slugs too hot at 1050 FPS, i dropped down to 960 FPS and suddenly i lost a lot of randomness in my groups
Shooting " hot " i would get 2-3 shots just fine, but then POI would shift 1/2 - 3/4 inch in some direction ( generally horizontal ) then a couple of shots would group OK there, but then POI shifted back to where i just was or very close.
So back then it was hard to shoot a good 5 shot group.
Now at a more ideal speed things stack up much better, and deviations in group size could very well be me or what ever little wind there always is even on the best Days in Denmark. ( i shoot about 10 - 15 degree uphill )
I can shoot my Maverick at really low pressures ( 70 or so BAR ) and still get the 960 FPS, but it is better if i kick them a little harder with 90 - 100 BAR
Mind you, when i just got my Maverick in its original 600 mm length, it was garbage.
1: it was set up strange from factory, with 90 BAR and #7 on the HS wheel it only shot 13.43 gr monster redesign pellets at 575 FPS,,,,, but like lasers.
Upping the speed to 800 - 900 FPS where others can shoot MRD pellets just fine, well not my Maverick, but at those speeds the Beast pellets would fly just fine, but also the only pellet that would do that at speed, and i tried like 12 -15 different ones from 3 major brands. ( 10 gr and up in weight )
None would shoot better at 800 FPS or more, and my 2012 FX Cyclone shot a lot better than my Maverick.
I did not try slugs back then, and my nightmare only changed when 1/2 year or so after the launch of the Maverick i was able to get a 700 mm barrel, it will shoot pellets a lot better and at higher speeds.
I have a intense HATE for that 600 mm liner.
2: Deeply let down by FX in regard to the Heavy .177 liner, it is the exact same TR as the regular liner with 1:18 twist rate, so basically the same liner with 2 different names.
I am inclined to try heavier stuff again, but then shoot it at slower speeds, i do think every time i have tried i have been above 900 FPS, maybe slow is the way to go with heavy.
1050 FPS with 20 gr Zan slugs, that is almost 50 foodpound of smacking power in a .177, sadly they will not fly good at those speeds.
