DD and Daryl,
Yes, I have found Gert the Belgian. He seems to be quite a fan of these sorts of rifles.

As for the weigh vs. volume method, I do both. I like the confidence of having weighed the rounds, but I don't always find that they do so much better. They never do worse however.

When I need to load a lot, I sometimes load by volume. But by weight is preferred. I use a Redding BR-3 measure most of the time. It is pretty good, but will vary about 0.1 gr either side of what I am shooting for occasionally. I also use a Belding and Mull or Lyman measure. I don't worry about plastic hoppers and/or steel vs brass.

DD, when I say I wipe every shot, I mean every shot. This is done in Schuetzen or silhouette matches. My standard procedure is to run a bore pig soaked in water, and pushed through with a dry patch on a rod. Not a problem for most breechloaders - it is faster than blow tubes. Of course, the Martini will be an issue. I don't suppose it has a hole in the rear like my BSA 22 did to allow a cleaning rod to pass through from the breech.

In herd matches where 25 shots must be made in 10 minutes, I use a bore pig every 5 shots.

In hunting situations, I hunt with a clean bore that has been wiped free of oil with a little Hoppy's #9 solvent and then one pass with a clean patch. If, an animal is shot that does not drop immediately, I will follow up with shot from a dirty bore immediately, and will continue to shoot as long as necessary or until the animal runs off. But once he is out of sight and range, I stop, wipe the bore with a Hoppe's patch and a dry patch before following up. Thankfully, this does not happen often.

I sure wish the rifle would get here. I sent the check on Thursday and I'm just a little impatient as always... Have been since Thursday of course.
