He then told me he had a pound and a half of t5010 I could have because he had no use for it and its similar in burn rate to 50 bmg. So he gave me the powder and Ive never heard of t5010 and I can't find anything on this powder so I'm sure it's been discontinued for a while and I don't want to work up a load for my 338 raptor with a powder ill probably never be able to find so my plan is to try it in my 338 lapua. Any thoughts on this I'm sure someone on this site has used t5010! Any input is welcome and appreciated!!
5010 is a good powder but I'd steer clear of the Talon stuff. Some of it didn't have the nitric acid neutralized properly and will degrade whenever it wants to. I had a couple of kegs of it and had to use one for lawn fertilizer; it just went bad too quick.
My advice is to load it similar to H50bmg but start a bit further down ( since it is mil-surp) and shoot it up. Don't use it for sitting around loads.
