I think BadAss Rocketry sends shell casings with their deployment kit… at least that’s what a club member here said, I’ve ordered one so I’ll find out. I guess the reason a small hole is not drilled in the base of the charge holder and the E-match inserted there is once done you have an active assembly?
I left the spent primer in the case. I was told that you don't want to have a hole for the hot gas to get into the AV Bay.
I looped them up and over , clearing the rim of the case by at least a quarter of an inch. Good launch today. We had a 3 good flights today. Two (one L3 and one L2) had apogees on the 24k / 25k range. We had our first COA to 50,000 AGL but it didn't come soon enough for our L3 guy to make a motor. The next one is 6/4/22.
For the third time there was a loud pop after liftoff. Loud enough that the more senior fliers thought the motor CATO'd. It didn't but when I pulled the liner out of the case it was burnt up worse than usual. No damage to the case,

The winds were calm or nearly so. Straight up.
On the main. The flight wasn't flawless. Prior to launch we discussed adding tape to the upper nosecone section since it came out about a 1/2" with no effort but then firmed up. The thinking was that the inertia of the rocket slowing down at apogee might cause the nosecone to come out. I elected to "try it". For me this is all about learning what happens when "little things" aren't right. The main coming out after the drogue and before 800' AGL just increased the wait time. But I will fix it before the next launch. The nosecone came out and pulled the main after after apogee. I'm not sure when. I have some photos after apogee and the nosecone was still attached. I know the charges didn't fire early because they fired right on time later.
Less than 40 yards from the launch rail
All laid out and ready to pack
Track. The darker blue line is when I picked it up. I forgot to shut the tracker and altimeters off.
