I came across a bunch of Winchester Mark V hullls. What load data do I use. I’m confused by the several different Winchester hulls I see listed. Are they all the same?

I’m trying to remember if those are compression formed or not.

hey woody , they look like CF's - use a light and look inside for a smooth base wad . I'll bring my old Lyman 2 over so you can see some loads for those.

I have the Lyman 2. I will bring a few Saturday or Sunday to the club to show you. Yes. Smooth but appears tapered? We have the big shoot this weekend.

Yes Woody, that is a compression-formed hull, and all Win-West compression-formed hulls of the same gauge are the same inside (load the same) regardless of the brass height or the type of crimp originally used - 6 point, 8 point, heat/swirl sealed or not. Yours is a hull from the late 60's, I think. The Mark 5 designation pertained to the wadding used - conventional card and fiber wads topped with a little polyethylene sleeve to protect the shot. The poly sleeve was the Mark 5 distinction and it's usage goes back to Win-West's higher grade paper shells, before they went to plastic.

Originally, Win-West's plastic hulls were of two types: In the cheaper loads, a thin-wall straight-wall ribbed plastic with the same paper basewads and fiber and filler wads as the paper hulls they replace. They were simply the old paper hulls with the tube replace with plastic. They loaded the same as the paper hulls they replaced. High-brass hulls had greater capacity than the low-brass hulls. For the higher priced premium loads, the hulls were compression formed and smooth on the outside (not ribbed), but often had a slightly swirly-textured look due to the flow of the plastic during the molding process. These all had conventional card and fiber wads, except the premium target load -- the famous AA -- it had the now ubiquitous AA plastic wad/cup unit. The Mark 5 designation and loading was put in the high-brass only, and had conventional card and fiber wads with, of course, the plastic shot protection sleeve. This was true in 12, 16 and 20 gauges, but it was a while before the 28's and .410's went to plastic, I think. I don't believe I've ever seen a straight-walled cheap hull in plastic Win-West 28's -- only compression formed. Until then, all the W-W 28's were paper. The plastic .410's, however, were made in the straight-walled ribbed fashion with paper basewads, etc at first and then eventually went to compression-formed in both 3" and 2 1/2".

Eventually, even the cheap loads were put into compression-formed hulls in 12, 16 and 20 gauges, but they were not Mark 5's, and had cheaper components and cheaper-looking boxes.

Since probably the late '80's it appears Winchester outsourced their hulls to a couple of different manufacturers, and were of the thin-straight-wall Rieffenhauser type (Cheddite, Martignoni, et al). These hulls are the same inside (capacity) regardless of the height of the brass. They all had/have plastic basewads. Of course in their AA target loads, W-W abandoned the compression-formed hull for the "HS" hull (High Strength), which is nothing but a Rieffenhauser hull made with really tough material, with a parabolic plastic basewad meant to make the hull perform and load similar to the old compression-formed hulls, which they essentially do in 12 and 20, but not in 28 and .410. As far as I know, HS hulls were unfortunately never offered in 16 gauge. The HS hull is for high-volume target shooters that re-load, and they apparently don't see the 16 fitting into that niche -- so far.

So lobby Winchester (Olin Corp) to make HS hulls for the 16 -- they'd crimp so nice, or better yet lobby Remington to make a premium 16 like the STS one-piece target loads. What the hell, dream big.
