IMO a page of 50 yard 1" groups is very good for any springer. I'd be happy with that from any of mine. Sure I've had half inch groups here and there which is MOA but they might be on a page with a 2" group. IMO consistent 2 MOA is better than a rare 1 MOA.
I'm a proponent of posting full pages of groups because it shows realistic results and not a single possibly lucky group.
As to using a 30 for 50 yard groups. I don't do it. I'm a fair marksman at best and too much of a perfectionist so it frustrates me. Light 177 pellets and long flight times makes environmental influences considerable. Therfore i typically only shoot 50 yard groups with >14 fpe. 177 at that power has shorter flight times and 20/22 cal pellets at that power has similar flight times as the 30 but considerably better BCs.

@20cal guy I'll routinely plink my scoped HW30s and 50 out to 93 yards (my current max available from my front porch). I have a 4" round plate at that distance that's easy pickens with a predictable wind. Medicine bottles and soup cans are more fun targets. I have shot lots of beer cans and small water bottles at 100-108 yards at other locations. It's great fun.
Long distance shooting is something I enjoy and do pretty well with. I've learned that cant error is my biggest concern. That's no matter where the rifle is zeroed btw. Shooting way down into the reticle only makes it more noticeable and understandable.
Reading the wind is next important to me because I have the luxury of cherry picking calm times to shoot. Even the slightest change in breeze affects the POI with light projectiles and the longer they're in the air the more suseptible they are.
Oh as mentioned earlier a finer point of aim will help greatly. I use 3/4" sorting stickers. They work out to 100 yards for me at 9x. I will often lower the magnification at closer ranges to shrink there size relative to the reticle. I'm not a big fan of high magnification. I can hit a 10" plate at 500 with my 1-6x scoped 223 AR. I hit the same plate at 625 with 3-15x 223 Varmint bolt gun. I know these aren't airguns but I'm using them for examples of magnification vs distance.
For long distance and target shooting the Airmax AMX reticle is fantastic because the bottom post is hollow and graduated. I'm often shooting though that ladder looking thing at long distances.
Anyways kudos to you for a page of good groups and remember to keep it fun.
Be well
