So, Hornady markets a Superformance factory load for the 9.3x62 using a 286gr SP at 2,360fps, which is a standard velocity for this round, but only offers it outside the US. From what I can see (although at least two US sources carry it including Buds).
I presume that the Hodgden Superformance powder is mostly equal to the canister grade the Hornady is using, so I'd like to know if anyone has bought a box and pulled a bullet to get a charge weight.
I'm thinking it might be a good starting charge for reload development as it's likely loaded light for use in older European guns, and not modern rifles like the CZ.
