Hi Everybody,
First post here but I've been reading and lurking for a while. I have 2 S&W 500 Magnums and after shooting a bunch of commercial loads, I am starting to reload for them. I have the 8.38" and the John Ross 5". I bought mat's bullets 335 grain TC and I'm having difficulty find load data for them. It says "This plain base bullet should probably be kept under 1300 feet per second." Okay well there is trailboss data out there. But that only gets you to <1000 fps and Ive been looking for trailboss online for years now and can't find any. I'm looking to get between 1200 and 1300 fps, and that seems difficult to find load data for.
I keep getting things like:
303534
Its either Trailboss or Ramshot Enforcer or something else with a starting load at 1500 fps or way higher.
I did find this for Accurate 5744 using 33grains giving 1249 fps for a 335gn plated HP which would be ideal.
303535
And well I don't have any of that powder. I do have Tightgroup, Ramshot Enforcer, CFE Black, H110, and 4046.
On paper, Tightgroup seems to be the best choice. But many people on this site and elswhere, including John Ross, have said that is a dangerous powder to load down and all of the blown up revolvers happened while using Tightgroup. From detonation or double charge I do not know. But I've been warned to steer clear of it.
Then I came across this little gem while reading "The Development of the John Ross/Performance Center 5” .500 S&W Magnum" by John Ross.
"In the .500, try a case full of much slower rifle powders like 4198, 3031, 4895, H322, H335, or BLC-2 These much slower powders fill the case entirely and the pressure builds more slowly."
So after this extremely long introduction I'll finally get to my question.
Would it be a good, bad, or terrible idea to use ACCURATE 4064 powder?
Its bulkier and slower burning than most others. Seems like a safe place to start?
Thanks,
Dan H
