I tried slugs for the first time 5.5 years ago and have never gone back to pellets since, I couldn't handle such a drop in accuracy.
If you want to stay with a relatively cheap ammunition, I do not recommend trying the top slugs, as it is an extremely addictive matter.
Here in the video I'm posting shooting with pellets ( JSB .22 18.1 grain). It's a video from 2017 at 205m.
I was extremely lucky to have one batch of these JSB Jumbo Heavy, which I bought about 30 000 pcs of in 2012. When I was looking for replacements in 2016-2017 as the supplies were running out. So I arranged to test all the series, which were 19 types of the same Jumbo Heavy, but each from a different machine. Only 2 of the 19 worked out of 120m distance and only one even had relatively good accuracy (not as good as the 2013 series).
The others series after 100m (some even after 80m) get to a large spiral and lost accuracy.
My 2013 Jumbo Heavy series in my very first prototype rifle Altaros M24 set up to 42J never flew in a spiral even after 300m (a few attempts and a few times hit, but a net coincidence in the wind).
And now a demonstration of why I'll never go back to pellets. The distance is the same for both vids, 205m even the location is the same and the rifle is also the same with the same power setting.
The difference is the size of the target, with the slugs I shoot at a 10cm diameter circle (about 4 inches in diameter).
Pellets - 205m
Slugs first prototype Altaros ATP .22 31gr ( 2 poorly made slugs were used in the video with smaller diameter)
I also recommend looking at the date the video was uploaded, which was not intended for official publication. We finished the CNC turned slug technology in the first extremely unfinished phase at the end of November 2018, so these are really some of the first initial tests.
Simply pellets vs slug is incomparable difference in accuracy at distances over 130m
