45 Long colt - The Firearms Forum

chasdog · 04-20-2012, 10:21 PM

Has anyone used Win. 571 powder to load 45 lc . Would like to hear some load info if anyone has anything on it. Looking for normal pressure loads . Specifically for hornady xtp 300 gr hollow point bullets or 255 gr cast bullets.
Thanks
Charlie

did you find this powder listed for this bullet and caliber? if not suggest you look at manufactures website.(the powder manufactures site that is)

WW571 (the same powder as Hodgdon HS-7) is pretty slow burning for standard .45 Colt loads.
It's more suitable for magnum loads like the .41/.44 Mag or the .454 Casull class cartridges.

Hodgdon doesn't list any loads for the powder under either name in their online manual.

yep the ol W571 is obsolete and isnt made anymore, but as Bindernut mentioend HS-7 is interchangeable and you can use HS-7 data to load with older lots of W571.

It is a bit too slow for .45 colt loads unless you are loading hot for a ruger or T/C singleshot.

Thanks guys I think 300 gr is too heavy for 571 I saw a load of 13 to 14 gr for a cast 250 gr bullet. Was just hoping someone had used this before on heavier bullets.
