loads
As far as powder goes, if you didn't know already, it's always best to find a load that is recommended for the actual bullet being used. I just found that out myself. If you have the Speer book, and bought Speer bullets, you should be in good shape. Also, for seating depths of the bullet, go by bullet manufacturer also, since they all might have a different taper or shoulder on the bullet. You don't want a bullet too long that it is riding up against the lands when chambered, this will cause more pressure. I don't know about the 700x powder, but it should work good when you start playing with different loads. I started loading .45 about 2 or 3 months ago, and finally got it perfect. I've loaded rifle for a while now though. For the .45, I use Hodgdon's Universal Clays: 5.9 gr. w/230 gr. Hornady bullet, 6.5 gr. w/200 gr Hornady bullet, and 6.5 gr. w/185 gr Hornady bullet. I really like Hornady... in ball, FMJ-FN, and the HP-XTP, all fully enclosed base. The 185's and 200's are a great light recoiling load for target. Watch out for the lead bullets frequently leading the barrel. Your results may be better, but my Kimber really likes these loads. I've also never loaded so light that I need a lighter recoil spring, I might play with that sometime in the future. Hope this helps
