I picked a bad time to start reloading for a new caliber, I just had a rifle built in 260 Remington, I stocked up on a bunch of 140 smks and Lapua brass as well as 8 pounds of IMR 4350. I know the H 4350 is the preferred powder but its nowhere to be found so I compromised(?) with IMR 4350. Looking for some favorite loads for this powder from you guys here that have experience with it. My barrel is a Rock Creek 8 twist 26 inch, chamber is standard cut, I did not want to turn necks.
IMR 4350 and the 260 Remington loads

H4350 is just a SHADE slower than IMR 4350. Look at the loading manuals and go from there. IMR 4350 is an EXCELLENT powder! However, it is not an "extreme" or "temperature INsensitive" powder>>>so stay just a little back of HOT loads and you should do just fine! Pushing the envelope to the edge will make even "extreme" powders become somewhat "sensitive".. By doing that you will only exacerbate the situation with IMR 4350!
