777 magnums

[john1911]

Anybody heard anything about these; http://www.hodgdon.com/tripleseven/t7magnum.php ?

I wonder if they are just bigger 777 pellets or a new formulation? The website list 2 of these pellets as max charge. Wonder how they will be priced?

Please don't bash me for using these new-fangled BP substitutes.

There is a test of different powders in the October issue of the American Rifleman magazine.The author list the magnum pellets as being 75gr. pellets.The chart shows two of the magnum pellets producing a velocity of 1850 fps. using a 245gr. Hornady SST sabot.Three 50gr. pellets using the same equipment produced 2106 fps.The test used 10 or 11 different powders and was about velocity and pressures,not much info. about accuracy.
