Our club allows loading two (everywhere but but most of the more competitive shooters load one at a time for all the singles shots.

I've done it both ways, currently loading 2. But it can be useful to load 1 if you feel yourself getting frustrated or edgy. It forces a dismount and remount. I will usually dismount and remount the gun if I miss the high house, just to take a breath and reset.

Whatever works for you is fine.

If you take forever on the pad shuffling your feet, tracing from center stake to the house and back to a hold point, readjusting your feet, etc. you'll have a hard time finding a squad that wants to shoot with you.

If your half way pleasant, step onto the pad and take care of business you'll be fine.

Tournament shooting is a different game than leagues or practice. The entire squad is expected to get done in a certain amount of time. Its your responsibility to not waste it. If you can get the job done loading one, go for it. But this is true of your entire 'routine'. If you're going to shoot tournaments part of practice has to be streamlining your approach to the station.

I shot with Bender for several years. Our whole squad loaded 1 at a time. We always finished our flight in under an hour.

I did it to slow me down and make me think about the 2nd shot but if you’re serious about what your doing it still isn’t slow.

That would certainly help some shooters.

Two.

I load two for singles because on 1,2,5, and 7 the process is closer to shooting doubles than having to load between each shot. It also prevents any embarrassment if I lose track whether it's a single or double.

Agreed and that is one of the most annoying delays for me.

I've broke a couple of people of that habit by stepping up and shooting in their absence then pretending I though it was my turn since no one else was ready to step on the station. Do it to the same person a couple of times and they will get the point.

This happened to me two days ago. I had a good round and was standing on 8 low with a 23.I loaded two since I had to shoot my option. It surprised my friend who was had the controller when I called "pull" immediately after my first shot as he thought I was going to reload.
We had a friendly discussion whether this was ok with the rules. Was it ok to load two on low 8.

Yes, and, if your friend was paying attention, he would have noticed that you loaded 2.

At my current club, we load two on singles except on station 8. Don't want a shooter turning around with a loaded gun. I've shot at clubs where the local rules are that for ALL singles you only load 1 shell. I found that somewhat annoying.

I just started shooting skeet after years of shooting trap. I load one shell at a time because that is how I shoot trap singles. I am old and confuse easily so it is better to be consistent.
Lots of us shoot trap singles with our bottom barrel and only use the top barrel for doubles. Doubles are not shot frequently at most clubs.

At our club, we leave the option open for experienced shooters; 1 or 2. The exception is station 8; singles unless you are straight for the last round. If we have new/inexperienced shooters, we pair them up with an old hand and have them shoot on a separate field, single shots only until they are comfortable with shooting before we have them shoot doubles. It keeps the old hands happy and takes the pressure off the beginners.
