450/400 resurrected thread

[15meter]

Read a recent thread where someone was looking for (I thought) data for 450/400. Can't find the thread, but figured I'd post the link here hoping the OP would find it.

I found this, then couldn't find the original thread to link this ancient thread to it.

Hope this finds it's way to the other guy.

I was in on at least one of those threads, looking for load data for 350-grain cast boolits. My old go-to for these big cases was XMP/AA 5744, but I haven't been able to find any lately. Closest I have in what I think would be acceptable burn rate would be H-4198.
That thread is on the singleshot forum.

Oh happy day! Powder Valley has 5744 in stock!:drinks:
