On our iPad and iPhones they are all combined in a single P column, but on the Kindle Fires we use for the posses there are columns for M, P, and B.

Kerosene or electric lanterns inside white 5 gallon buckets are the best I found, placed down range of a hay bale or such so they are not visible to the shooter. Bucket protects them from splash and dims the light drastically. Red lights at load/unload tables. Easiest to do all knockdowns or paper, as you can’t spot steel unless you paint between shooters.

I have loaded 15.3gr H110 under a 160 LGCSWC and it makes a 20” Rossi shoot like a real rifle. Haven’t chronographed them, but shoot real flat. Loaded a bunch after being faced with 300 yard rams and main match ammo at a match last year. interesting, but Lyman stops short of 16gr with a 155 LGCSWC...

1/2” is what I have used for .44-40 and .45 Colt, cut into roughly 1/2” sections. You can find it in 20’ lengths in the screen door/window section of the hardware store. Looks like 20’ gray licorice whips. If I did this right a link to some carried by Home Depot is below. https://www.homedepot.com/p/Frost-King-E-O-5-8-in-x-20-ft-Polyurethane-Caulk-Saver-C23H/202262332?MERCH=REC-_-PIPHorizontal2_rr-_-206783276-_-202262332-_-N

+1 for caulk backer if you need to use filler. Vaporizes upon firing and I have never heard of it compromising loaded rounds.

Our knockdowns (mostly US poppers) are 3/8" AR500 with 1/2" pipe stick welded to the bottom to mount in our bases. For static targets we've been using 3/8" and 1/2" mild steel for years, and they age pretty well with lead bullets and cowboy loads, but are getting too heavy for most of the folks willing to come out and help these days (not to mention being easily and heavily damaged by boneheads with rifles). We are gradually changing over to 1/4" AR500 targets with a small rectangular slot centered near the top so they can hang from a hook made of 3/8" AR500. Very much like what MGM sells for Steel Challenge if you want to see examples. We initially went with 3/8" AR500, but I saw another club using 1/4" 18"x24" targets that are aging very well in speed steel matches, in which they are getting worked over heavily with jacketed 9mm, .40S&W, & .45ACP, from both pistols and carbines. Since then everything I buy is 1/4" and they are much nicer to haul around. I just go to Pacific Steel with a cardboard template or drawing and they use a plasma cutter; I've not seen any issues with wear or such in the heat affected areas. For long range targets (and even Plainsman rifle targets) the 3/8" AR won't crater, but starts to bow pretty quick when it gets whacked with a few 405 or 500 grain bullets.

Can't answer definitively about the "antique" classification but will tackle the concern noted above about getting them back into the US. SImply fill out a customs form 4457 and have the guns verified by a customs officer BEFORE leaving the states. This form provides the proof that you took them with you so you will not be accused of importing them on your return.

I'm sure it's been longer than I think, but Numrich Arms (now Gunparts Corp) used to sell conversion kits to change your model 94 over to .44 Magnum. I think the "kit" may have consisted of nothing more than a barrel and carrier/lifter. If so, that will answer your initial question, at least for the larger cartridge.
