Looking for data for 260 Remington. Have a XP100R in a 260 Remington. SR4759 use to be the go to powder but no longer being made. What are the go to loads now. Any help??

I don't load for the 260. But if I were faced with your situation, I would look at Accurate 5744 or Hodgdon H4895.

If I could find either I would I do have all the guys at our gun shop on the look out for some H4895 but last three delivery no H4895 has come in maybe this week some will I can always hope.

Been out of IHMSA for a long time but did have a rear grip XP100 in 260. Someone suggested 32 grains of H4895 with a 140 grain bullet when the gun was brand new. Got a 40 on the first round with friends giving me sight settings. It chronoed 2100 or 2150. That's all I have..Tim ...a very old 45128
