I've been wanting to give it a try with 70 RDFs in the 22 Nosler ( bought a bunch when SPS was practically giving them away) but just haven't had the time. Slower powder just makes so much sense. Also going to try cooler primers (WSRs and BR-4 vs the Feds I've been using). A switch from Feds to BR-2s in my S'more did wonders for reducing peak pressure with 140s and slowing bolt unlock across the board. If that doesn't work, I'm not going to waste H4350 on it and I don't think I'd allow myself to buy a pound of Lever just for the 22 Nosler lol. The barrel will be going in the back of the closet like the plan was before I saw Hodgdon's data
Try RL26 is the CM.
My pet load for the 260 and CM has been 143 eld-x over 42.3gr H4350@2810 fps from a 26" barrel.
With lower pressures I'm getting a 2905 average with RL26. Thus far it hasn't displayed the temp sensativety of RL17 either.
