Good or bad, I'd like to hear what your results have been and why you like it or don't. Have new rifle coming, have sectioned a case (looks fine to me)....comments please. Thanks, r in s.

Most folks find that the 1 in 10" twist factory barrels aren't the best choice for accuracy. Check out the information available at www.wssmzone.com.
I have had really good luck with my 25 WSSMs and have shot 1 deer with the 223 WSSM 64 grain Winchester/Olin factory load. That bullet shoots good groups in my Winchester/USRA 70 stainless Ultimate Shadow. Remember that the 3 WSSM cartridges are loaded at, or very close to, the maximum safe pressure, so don't expect to get more speed by reloading. Also, FWIW, I like the Federal WSSM brass better than the Winchester/Olin brass, particularly the nickle plated variety.

Likes: speed, and lots of it. We get 3700+ with a 60gr Vmax, 3800+ with a 55gr Btip and 4050+ with a 50gr Btip (starting load in the 50gr). The 60gr Vmax is a coyote hammer.

Dislike: very thick brass/necks, short case life of 4-5 loadings.

Rifle is a Browning Abolt. Very accurate with most loads.

Whooeeee. 4-5 loadings.....that's unlike any caliber I load for. Going to stay with the black 55gr. Win./Nos. bullet as loaded by Winchester...thanks all!

4-5 loadings is some what typical of high pressure balls to the walls type cartridges. I'd suggest reloading though, the fact that WSSM's are basically out of Browning and Winchesters new line ups is probably not a good sign, ammo will eventually follow into no mans land as well.

FWIW, I have a Winchester/USRA 70 with a heavy 1 in 14" twist 25 WSSM barrel that is mostly used for shooting the 75 grain VMax at pdogs. I have been using Federal 243 WSSM brass and some of this brass has been loaded x8 without any problems. I am running high pressure loads, but the Federal brass is thinner than the Winchester/Olin brass, so it will expand to seal the chamber at lower pressures. The Winchester/Olin brass is so thick/heavy that it often won't expand, even at maximum recommended loads, so you'll get smoked necks. That is a problem that I never have had since switching to Federal. Graf & Son in Mexico, MO, is my source for Federal WSSM brass.

OK Rem guy, just placed an order with Graf today for some 55gr. Win/Nos. Supreme BT, thought Win. my sole source and have about 400 fired cases....I assume inserting a primer into a loose primer pocket equals a culled case. r in s.

I don't know about that loose primer pockets are a feature of culled brass, but I wouldn't load them myself. I'm using 45.0 grains of Varget under a 75 grain VMax in the Federal 243 WSSM brass to get 3585 fps from my 23" barrel. After almost 1800 rounds, this barrel will still consistantly shoot sub-MOA groups with this load.

Before I'd spend a lot of $$ trying to get a 223 WSSM to shoot, I'd ask the experts at wssmzone what recipe they are having the most success with.

Jeff

The wssm family of cartridges are perfect! Great case design and super stiff action. I've never seen one that didn't shoot MOA. All I do is anneal and neck size. The short action bolt throw is addicting. The 223 wssm is amazing with 60 gr partitions. The 25 wssm has become my constant companion.
