I'm wanting a reduced recoil load for my 260AI that doubles as a fireform/plinking load.......so I want pressure 50,000 psi or more to form the shoulder of the AI cartridge. Hoping my daughters can use this as a hunting load.
I have a box of the 123g SST that Hornady makes for the Grendel. Per Hornandy, these are made to perform at the slower speeds of the Grendel so shouldn't be pushed over 2,700 fps.
So I'm thinking 36.0g of Varget with the 123g SST for roughly 2,700 fps MV and, per Hodgdon, 50,300 PSI. Another plus for this load is that on 125g and 120g bullets, Nosler shows 35.5g and 36.0g (starting load for 120g and mid load for 125g) as the most accurate charge with this powder and both are at similar velocities.
Thoughts, or an alternative suggestion? Another powder that might work well is IMR-3031. Hodgdon shows a max load of 34.0g getting 2,720 fps at 57,600 psi.
