:-D
Just saw this post on the old 40-82, what a great cartridge it was and still is. Being the proud owner of many old 86's, including several 40-82's, I find the best load for them is using AA-5744 powder and the original 260 bullet mould made by Winchester long, long ago. Although several other moulds work well too, I like using my oldie best. Just about any 260 grain bullet mould will work fine if diameters are in line with your groove measurements. My best shooting 40, has .408 groove but likes a plain lead (soft) bullet from the old .406 mould. I shoot this bullet right from the mould, no sizing but I do grease them by hand. In this manor, the soft lead can "pooch-up" to fill the grooves, giving great accuracy clear out to 200 yards. If your looking for great performance, say around 1500 fps, which is very close to the original BB velocity, try 25.5 of AA-5744 behind your favorite 260 grain mould. Another thing I do is, push a wad onto the powder made of good old toilet paper, keeps the powder back against the primer better and really does improve on accuracy. I use one piece of 2-ply for each case, rolling them up, followed by seating using a wooden dowel. Now for something thant can be a pain: All three of my 40's have what I'll call very tight neck measurements, meaning the bullet I use has a little trouble going into the chamber due to over-all neck measurements of the loaded brass. Having worked with these rifles for years now, I can't see how they ever used .408 bullets in them as mine won't hardly allow chambering a .406 bullet, much less anything larger. Because they were BB rifles, its my belief they were shot with smaller bullets on purpose in order to get more rounds fired before they powder-fowled and the use of soft lead allowed for good accuracy because the bullet expands better than a hard bullet does. For this tight neck reason, I made a die for compressing the necks of my loaded rounds just aboit .0002 and in this manor they chamber easily and fit perfectly streight in the bore. Anyway I slice it, this is my formula for getting the old 40-82 to shoot well, like inside 4 inches at 200 yards, most of the time..If anyone has other ideas I would love to hear from you, please write.
