I am about to start working on a deer load for bro's new 788 with 60gr Nosler Partitions. I figure there are enough newbys that might benefit from listening to us discuss it while I work up the load, failures and successes.
I shoot 53-55gr in mine over 3031. I have never tried anything heavier in that rifle nor in any of several others I have loaded for, so I am open to suggestions as to what powder to start with with a 60 grainer. I have in point of fact never loaded any bullet heavier than 55gr in any .22cal centerfire so I am out of my comfort zone a bit here. The closest I have come is a loading student testing all the really heavies in his AR and me finding good safe loading data for him. And that doesn't count.
My goto powder isn't on their list, nor several other favorites, but Nosler's website lists a bunch and these are the five from their list that I have on hand:
A2520, RL15, IMR4895, Varget, 4064.
Which one do you think I should start with?
Birdz left me about 5lbs of RL15, he used it like I use 4895. I will probably start there if no one has a better suggestion.
My loading manuals are all in storage now with the rest of my library, so I am a bit hampered in my ability to sniff out potential good loads. If anyone has a different powder you think I ought to try, I'll get bro to cough up the cash for some. Like I need another powder in my cabinet.
