: I looked up some of my old 9.3X62 loads. The rifle I had was a Carl G sporter with double-set, double-throw triggers. The 23.4" barrel was a bit rough, but it shot well with fairly warm loads, less so with factory duplication-type loads.
: My best powder turned out to be BLC2 in RWS & formed '06 brass. My top-end load was 65.0gr. with the 286 Norma bullet for 2,519fps, and 68.0gr. with 270 Speers for 2,675fps. These were stiff loads, but showed themselves to be just fine from brass longevity. I used case head expansion to arrive at my max loads. Using H322 powder, I loaded 250gr. sper bullets until they started to stick, which happened at 61.0gr. with an expansion of .4763". I called .4750" expansion as maximum, which showed that level of pressure to be a good safe maximun from brass longevity.
; The 286gr. load produced 4,033FPE & the top 270load a whoping 4,293FPE for those interested in those numbers.
; Like I said, they were stiff loads, but quite safe in my rifle. I used CCI250 primers. These loads should be worked up to, from a starting load of 58.0gr. My rifle also had a fairly long throat, which contributes to case capacity by seating all bullets out to fit the magazine.
: Using BLC2, I never experienced even a slight hesitation in bolt lift, form the loads I used.
: Testing the above loads in formed .30/06 brass showed less pressure and velocities.
: I strongly caution to develope your data as I did, according to case head expansion, with maximums based on brass longevity. Mine lasted over 15 shots before I sold the rifle to a friend. He got all my brass, still going strong with tight primer pockets.
: In all, I experimented with W748, W760, IMR 4064, H322, BLC2. Today, in the 9.3X62, as with it's sister the .375/06IMP, I'd use Varget, H4895 and probably stay with those excellent, Hodgdon "Extreme" powders for their temperature stability properties.
: BLC2 deserves a test run though, of loads from about 58.0gr. to whatever becomes a max load in our rifle as it just seemed work perfectly in this case. I must also try it in my new .375/06. They are so close to each other, in calibre and case capacity, as to be one and the same.
