I am loading for 22 Hornet, 50 gr. V-Max. My Lyman handbook #45(1970) lists 9.3-10.3 as start and max loads for this powder. Speer #10 lists 7.5-8.5. Is this due to lawyer nervousness, powder changes, or better testing of pressures? I am shooting these in a Ruger 77/22 and Tarus Raging Hornet, so can I safely up the ante? Primers are some what flattened, but not excessively so. I usually check load data on the internet , but their site is down. DALE
