Hmm. I bought some re-packaged Vectan SP7 from him two years ago or more...and it took the primer clean out of the bottom of the case when I tried the first round...loaded to 5% under the starting load recommended in the Vectan manual.
It caused me to have doubts about whether it was really canister SP7 or "bulk grade" SP7. Spoke to contacts in France who said that that loading, in that cartridge, with standard canister SP7 should never have performed that way.
I would NEVER buy powder from him again.
