I load for my 22 savage high power and a local foundry helped me out in the past giving me a handful of 55 grain cast boolits to experiment with.
The issue is that the 22 savage rifle(savage mod 1899 from 1918) has an across groove measurement of 0.228", the 55 grain had to be powder coated several times to get the diameter up to 0.2275 - ish and tbh the performed well but not great.
They decided to cast some 0.229" boolits as I mentioned above and are sending 100 or so in return for feed back on performance, thereafter I'll have to buy them. FWIW the boolits have one of those wonder coatings on to make them slippery and can be loaded to jacketed mvs, though I'm rather sceptical about that because of the relatively low BHN of 15.
My PITA is I need a start point to get this motoring.
The powders I have at my disposal are Lovex (world powders?) D036 which is similar to unique, S062 and S065 similar to TAC and Varget respectively and D0735 and D0736 which are ballpowders and equivalent to accurate 2460 and 2520 respectively.
I also have Hodgdon Universal, CFE223 and H-Lvr, Alliant 2400 and Vhitavuouri N110, N120, N140 and N150.
The Lovex reloading data has a start at load of 25.5 grains of S062 for a 70 grain jacketed bullet or 27.8 grains of S065, muzzle velocities within 50fps of each other and the S065 1430 psi LESS pressure than the S062. I've used both these powders with the 70 grain S&B bullet, also with the 70 grain Hornady bullet and also used N110, N120 in lesser amounts this is really just for info as the VV powders are really not producing the same velocity as the Lovex ones.
Does the team think that the Lovex start at load minus 10% would be a safe start point for the cast boolits?
Or is there someone out there with a different recipe?
A little more background info, the gun has a 20" barrel, despite this the mv's I'm getting exceed the lovex numbers out of a 24" barrel by about 50 to 80 fps. I can't see any of the commonly mentioned pressure signs re primer, sticking cases etc.
