Ok, that's custom ammo. It is not Federal Power-Shok as was stated. There are several sources for custom ammo but I knew Federal never offered .303 Sav.

My brother in law just got a Savage model 99, cal.303, from a neighbor. He wants to shoot it, & reload if he can. I can't find out any thing about the Savage--303, except in the 10th edition of "Cartridges of the World". Can any one steer me to a web site, or provide info. on this rifle & cartridge ?
Does any one manufacture brass for it ? Can you buy brass, etc. for it ? Thanks

Hawky,
Thanks for the site info.

Brass and factory loaded ammunition is no longer available. Fortunately, the dies are and Bertram make a .30-30 basic case which can be formed to the cartridge. I believe Old West Scrounger has the .303 Savage listed and Buffalo Arms has loaded rounds available as well as formed brass. I don't know if the cases can be formed from .30-30 directly but I would assume it is not as simple as using a "basic" case. Pet Loads by Ken Waters contains some loading data on the round and reports the original factory rounds were typically loaded with 180-190 grain .308 diameter bullets and Savage barrels were usually 1-10" twist. This appeared in the November 1967 issue of Handloader magazine.
Good luck with the rifle.

You can make .303 Savage brass from 30-30 Winchester brass. Basically, it's as simple as running the brass through the .303 Sav. full length sizing die and trimming to proper length. Loading data is easy. Just use 30-30 data. Bore diameter is .308, just as is found in the 30-30.
Winchester loaded the ammo with a 190 gr. Silvertip, and Remington used a 180 gr. round nosed Core-lokt, IIRC.

That's the easy part.Where things get a bit sticky is the 30-30 brass is a bit too small at the base just ahead of the rim. This makes for an ugly bulge at the base where the case expands upon firing. I know, I've done it.

I sold my .303 Sav. before I tried this idea, but I'll pass it along FWIW. I know I'll try it if I ever get another .303 Sav. After sizing and trimming the 30-30 case, take some 1/8 to 1/4" wide tape and wrap just enough to make a snug fit in the chamber, so that the case is centered in the chamber. Put the tape just about 1/16" ahead of the rim. Fireform and there should not be a bulge. After that, remove the tape, and load as normal. A starting load for the 30-30 should do the job.

If you want to try the 190 gr. bullet, RCBS makes a mold (#30-180-FN) that will cast out at 189.9 gr. average in wheel weight metal. Usually, 28.0 gr. of W-748 will give the proper velocity for that weight bullet. I also use that load in my 30-30. I've always thought that Winchester screwed up by not providing that heavier bullet in the 30-30 as well as the .303 Sav. Gun writer, Sam Fadala, in his book on the 30-30 laments that Winchester never sold that bullet as a component for reloading. He had to buy loaded .303 Sav, ammo and pull the bullets to use in his 30-30. That 190 gr. cast bullet is a real thumper on deer.
One of these days, I'll probably pick up another Savage 99 in .303. I'll be sure to try out my tape idea when I do.
