I am looking to see if anyone has done some load development using the Superformance powder, under a 55 gr bullet, in a 243 win.
I have had great luck with this powder pushing 70 gr Nosler ballistic tips. Now I was thinking about trying the 55 gr Nosler Varmint bullets but don't see any load data at Hodgdon. I was thinking about using the starting load data for 65 gr bullets and then going from there. Any experience with this combination or recommendations would be great.

There is probably a reason for that. I think that if you want to try them, you should go with a powder recommended for the ultra light bullets in the .243. There is not much to be gained after 4000 fps, which can be had with Varget and published data. I have loaded the 55 gr Nos. in two different .243 rifles, and the results are interesting, and accuracy has been OK, but not as good as with some other combinations. It doesn't matter how fast you miss them, you know.
 
I am not looking to break the 4000fps but instead looking at an alternative powder choice considering the times that we are currently in. The load will be possibly used for coyotes and gophers but most likely to punch paper.
 
"...under a 55 gr bullet, in a 243 Win..." What's your rifling twist?
"...thinking about using the starting load data for 65 gr bullets..." Um, no. You need data for that powder. It appears Hodgdon doesn't reccommend that powder for light bullets. You might want to send 'em an e-mail and ask 'em though. It could be that they just haven't worked up any data.

I agree that it is not recommended by hodgdon but I am sure there are reloaded out there who experiment outside of the recommendations. That is what I am looking for, has anyone tried this combination?
