Notes: This is an experimental load using the new shot produced by the Tungsten Spheres Company. It is safe in my particular gun/choke; I make no guarantees beyond that. Please note that you must protect your barrel and choke from all direct contact with the tungsten shot traveling down the barrel. I would highly recommend that anyone thinking about loading tungsten shot should read the fine booklet entitled Handloading Hevi-Shot by Ballistic Products. Typical patterns are insanely dense and penetration is outstanding. It is not uncommon to get 15-20 hits on a sheet on notebook paper at 50 yards and 9-14 hits at 60 yards. The real down side is that there is $7.00 in shot in each shell.
