There are no magazine or gun bans in Delaware no registration. No restrictions on ammo sales other than the federal ones that apply to all states. DE does not allow folks to register machineguns or silencers though, not since 1934 when the NFA was passed.
For some reason Midway USA seems to think we are part of Massachusetts, IDIOTS, and wont ship ammo here. I buy from AIM, or ammo man, or any other online sellers.
We have a range protection law which forbids folks from moving in next to a range and trying to have it shut down via lawsuit.
The state runs a decent range that is a state park, called Ommelanden. There are a few private clubs that are reasonable to join. I belong to delaware state pistol club, DSPC is an indoor 9 lane 25 yard club dedicated mainly to Bullseye pistol, but they have silouhette (.22lr) and youth air rifle and .22 programs as well. Where I live in northern DE there are rifle ranges in Pa within easy distance. I belong to a good one, Delco field and stream.
Atglen is farther away but better for long range rifle since they have a 600 yard range.
I have a CCDW it requires a bit of paper work and a $120 training course. Its not shall issue, but everyone at my club who has applied and taken the course has gotten a license to carry with no problem. Open carry is legal but seldom practiced. The state constitution gaurrantees the right to keep and bear arms for all legal purposes, self defense, and sporting, no mention of the militia.
Your 10/22 magazines say no DE sales????????????????????????????
The gun shop down the road just go in a load of the Hot lips magazines that hold 25 rounds IIRC. They are selling G-17 17 rounders for $25, latest production, 30 round AR-15 mags, and they even had Glock 33 round G-18 mags for $50.
