.260 AI...???

Re: .260 AI...???

Yeah, there are still some folks shooting these (me included). Terry's data was pretty spot on so definitely a good place to start. I've also shortened the OAL a bit to better fit my rifle and the results continue to be excellent.

What else are you looking for?
 
Re: .260 AI...???

I have a 24" barrel on mine and H4831 didn't reach desired speeds with a full case so I switched to H4350 and haven't looked back. I can drive 140's to 2900fps with no problems.
