For all you 9,3mm shooters, mountain molds now make a bullet mold. | ||

Thats good news. Please tell us homepage adress and specifics. I�ve heard Makarov moulds could be used for training. But thats plinking to different POI mostly. Thanks, Hermann | |||

Adress is mountainmolds.com. I have used a 260grs mold of my own design for nearly 2 years, and usually shoot .75" groups at 2200fps from my '64. | ||

I own an ancient, unused, single cavity Lyman 366408 that I intend to break in in a not too distant future. | |||

Erik-- Is that mold on mountainmolds.com a design of yours? I've been working on a mold design for my CZ-550 in 9.3 x 62 that is essentially a Lyman #311291 fattened up to nominal .366", with a flat meplat in place of the short radius round nose profile. I like the website design as well--the adjustable elements provided by the website will enable me to send the design we cobbled up and have it work pretty well. In my rifle--the nose will be .500"/12.7 mm long, and the driving shank will be .600"/15.2 mm long. This enables seating into the neck without powder space intrusion, slight engraving of driving bands into rifling origin, and is of a length to allow magazine usage. | |||

Eirik-- Yes, it will be a bore rider design. The throat in the CZ-550 is relatively deep, and the lands are fairly tall, too--.007". This caliber is not very well-established in the USA, but now that Tikka and CZ are both importing affordable good-quality bolt rifles in this caliber, that situation may change. I'm not interested in maximizing velocities in this caliber--1600 to 1800 FPS is where most of my rifles find their best accuracy with cast bullets. A 285-300 grain bullet at 1800 FPS is a pretty formidable game-taker. Like you, I want an affordable practice round to prepare for hunting seasons, and the 9.3 x 62 seems to be a potential winner as a cast bullet caliber--good casing/bore capacity ratio, relatively slow twist rate, and good striking energy with heavier bullets at cast bullet velocities. If accuracy can be had at higher velocities (2000-2200 FPS), all the better. | |||
