Daryl,

My experience with BLC-2 in the 9.3x62 is similar to yours. I have a Husqvarna. The load I use as standard is:

67.0 gr. BLC-2, 270 Speer, Norma brass, CCI-250.

Chronographed velocity was 2555 fps. in my rifle.

I also seat my bullets out to the length of the magazine, yielding an OAL of 3.385". The long throat of my rifle is still way ahead of the bullet at this seating depth.

I have found BLC-2 to be super consistent and finely accurate in my rifle.

Standard cautions apply for anyone who wants to try this load. Reduce appropriately and work up.
