I've never worked up a new load before - a mate worked up a load for my .243 (which was very accurate so I didn't search for anything better) but he's since moved away from the area and I now need to work up a load for a new .260. So hope you don't mind me running a few thoughts by you guys for a sanity check I'm not doing anything stupid!
I've had good results with nosler BT in the 243 so going to start there, with the 120gn bullets for the 260. I've also got some H414 handy, which by chance looks to be high up the list of "fast" powders in the Lee manual, so seems reasonable place to start. Lee Manual load looks to be 42.5gn to 45.5gn max.
So I was thinking of loading up 5 rounds at 42.5gn with an OAL 20 thou off the lands, another 5 at 43gn, 5 at 43.5gn etc increasing in 0.5gn thou increments up to the max load. I've also got some CCI large rifle magnum primers - good or not?
Firstly, can someone with a Hogdons manual just check the load data for me and secondly, anything I'm doing wrong or could do better?
Incidentally, barrel is 21".
Many thanks in advance!
