Hi Viv,
I agree with Roy, weigh each load, then fill a load of philes, files, vials, phyles (plastic or glass tubes with lids ), which are available on flea bay and are not expensive. The when you're at the range, you don't have to mess around with measuring, weighing loads etc, just pour them into each chamber and load as usual. I stand mine in a black plastic trays (which hold 50 tubes) that I get when I go to the hospital to have my blood taken (as I'm on permanant Warferin) which the vampires are glad to give you, as it saves them the job of binning them
When you say a cylinder loading tool, do you mean a stand ? as I use one that I made which holds the whole revolver. I have seen those that you place the cylinder onto the base and it's a sort of press. But I think it would be a pain having to remove the cylinder each time you want to load it. The type I made is quite easy to do (if you're handy with a saw and chisels), as all you need is 2 pieces of wood and a hinge, or you can even do without the hinge and have a fixed one, but the one I have fits into my case easier, as it folds. There are a lot of different designs around, which I'm sure many other BP shooters will tell you, so it all comes down to personal preference.
I hope this has been of some use to you.
All the best
Baz
