Picked up some Speer 275 grain GDHP and found plenty of load data.
I buy a lot from MBC and they just have 240 grain RNFP but no data.
Anyone load these?
 
I think you mean 340gr. Consider that that bullet is really only good for plinking, I'd just load it to around 1000fps with whatever fast-medium powder you like.

I use mostly the 355gr Oregon Trail over H110 at around 1400fps for deer/hogs.

I picked up a bunch of the 275gr Speers but have yet to test them.

Yes 340, it's a finger thing! LOL!
