Yes the S Type are the best way to go. That is what I use for my 264. But here is the most important thing that you will ever do for a magnum belt. You should also purchase a sizing die from Innovations Technology. Greatest invention for belted magnums EVER! Can be purchased on the website, look it up. Only thing that solves the case stretching and build up of Brass in front of the Belt. Regular dies do not size in front of the belt. Cases stretch too much and can split after several reloadings. Also allows you to set shoulder location bump consistently. Like the wheel did for transportation! Also if you want great 264 brass, buy Peterson 7mm Mag brass and resize it. Simple. Couldn't give a 16 year old boy better advice on his first date. Now if we could just get the manufacturers to build 264 wins with a proper throat, we would have the other part of the equation solved. all because Winchester wanted to advertise shooting short light bullets at up to 3900 feet /sec. Only good for groundhogs, what a waste. It also gave it a reputation for burning out barrels. WELL NO SHIT!Looking for a 264 Win mag FL die. Preferably an S type Redding, but let me know what you have.
