Reloader 19 in 30-40 Rifle
Posted: Fri Oct 14, 2022 4:16 pm
Ok I'm running out of IMR 4350 which my rifle loves behind Hornady 210gr bt ballistic tips. I went searching through my powder locker and found an unopened
can of Reloader 19 in the back that I bought with a powder lot from the relative of a departed reloader some years ago.
Now I'm no wildcatter I build loads on published data playing with it until I find what that particular rifle likes. Going through all the bullet and powder manufacturers books including Alliants I couldn't find any data for that particular powder in the 30-40. Knowing that it's a slow burner I figured it would be good behind the heavy bullets and in the long barrel. I contacted Alliant and their response was they have never experimented with that powder in that round so a dead end there. I did recommend they try it but hold no hopes.
So by working off the burn rate chart I found a powder listed just below Reloader 19 which is IMR 4831. There are multiple loads from multiple sources using that powder. Based on data published by Nosler, Sierra, Speer and IMR it looks like 41grs of IMR 4831 will provide 1900fps +/- from the 30 inch barrel and 42grs will provide 2000fps +/-. I've loaded some of both yesterday with the Reloader 19 but the weather is lousy and commitments will keep me from the range until next week. What do you guys think about this loading? Have any of you used it before? Any input is appreciated.
