My HW100 and Daystate Regal sub 12 in .22 would group the size of a 2 pence peace when shooting indoors at 50 yards/meters but when shot outdoor with all the variables it opened up to 2x/3x depending on wind.
They are limited by the performance of the sub 12 performance and not the rifles.
50 yard outside will be fun and challenging especially in the wind
Yes .22 will easily travel 100yds. Simple but counter intuitive answer is that a heavier pellet will fly slower for any given power level but will retain MORE energy at all distances & be less affected by wind. If you want descent groups, use the heaviest pellet with the best BC that your gun will shoot accurately with repeatable consistent velocities, combine that with weighing your pellets & visually inspect them when weighing them & either shoot indoors or on very still days for best results.
Problem with springers is they usually perform best with lighter pellets, there are some highish BC pellets in the 13.5 area, if your gun can shoot them well, they would be your best choice. You can push a 13.4grn pellet with 0.026 BC to 635fps which is exactly 12ft/lb which still has 4.9ft/lb at 100yds.
YMMV

Best I did with a full size HW100 at 50 metres was a 10 shot group 8mm x 13mm centre to centre rested on front and rear bags. Outdoor range but no wind to speak of.
I had a tx200hc years ago that would print groups at 50 yards with ease, it was .177 flavour and was a fantastic rifle, had it for years, my only gun at the time and wish i still had it now.
Moved onto pcp’s, as stupidly i thought they were More accurate than the springers 😌. The multiple pcp’s i got after wasnt a Patch on the tx, but then again i didn’t keep them that long to get the best from any of them.
wish i had a time machine tho, The amount of guns/cars/bikes/tools/gadgets iv traded/sold to get something i thought was better 🙄, probably why i keep everything i buy these days, most things anyway.
I've found about 70 yards max with .22 cal and achieve good results, Around the 90 yards with 177cal. That's all I seem to do now is plink or target shoot,
Sub MOA groups are theoretically possible BUT a sub MOA group at 50yds (i.e. half inch group) is much, much easier than one at 100 (1 inch group). I do not know of anyone who has shot a sub-12 1 inch 100yd group but plenty (myself included) who have done 1/2inch at 50yds. It's a real challenge.
