I saw some older posts on this caliber and rifle but nothing recent.
I have two BSA cadets. One is in the original 310 caliber and the other was rechambered to 32-20. One is in the original as issued condition. The 32-20 i restocked in walnut and had installed a PH peep with a front aperture. LBT made me a gascheck 100 gr mold that casts about.319 with wheelweights. I size it to .318 for the .316 groove diameted of the barrel. It shoots absolutely wonderful. everybody loves it when i bring it to the range.
The one in 310 gave me fits at first with severe leading problems until i used a pure lead bullet, and the leading went away. Apparently the harder bullet was not obturating well allowing gas cutting. I use CBE's 120 grain mold, and a fine mold it is. i lube the bullets by rolling them in Lee's liquid alox diluted with alcohol then standing them up on wax paper to dry. My best loads have been 5.0 and 5.5 gr of AA9 followed by 4.5 gr of Unique.
I would be interested in hearing from other Martini cadet shooters. Anyyone have one out there they want to sell?
