Hi I Just Ordered a new barrel for my Mod 70 in 223 WSSM with 1 in 14 twist I plan to shoot 40gr varmiator and 52gr TSX. I need some load info can any one help. Thanks B
Does anyone have any idea why there seams to be little published load Data. I have never shot the 223 WSSM is there a reason for it's lack of popularity. Everything I have seen says it's faster with better accuracy than the 220 swift and the 22-250. Dr B
It takes awhile for the Bullet and Powder Manufacturers to get the new Test Barrels and SAAMI Certification Loads. Then once they have them, they have to go try many different combinations to see what works well together. Once they have confidence in the data, they need to get it in a Manual or posted on their Web Sites and that also takes time.
Meanwhile Winchester is hoping folks will just spend the money for Factory Ammo. Eventually there will be lots of data for you, but it just takes awhile for them to get it all in place.
Best of luck to you.

I just had a look at a couple of on line reloading pages. Imr and Hodgdon and the loads shown with the same powders in the same bullet weights show the .223 WSSM to be on par with the .220 swift loads bullet weights and powder types being equal.Both do not list the bullets you want to use which sucks. The listed barrel lengths do differ with the 223 WSSM being 24" and the .220 swift being 26" if you have a 26" barrel you should be able to do better. Last weekend I got to check the speed on my reloads. Using a max charge of H414 in my swift and it averaged 220 fps faster than Hodgdon shows on the load page. I got a funny feeling you will be able to do better than listed speeds which is a good thing.
