Rem 7.5, Tula srm, cci 450/br2 are a must. In a small rifle primer the term magnum does not mean a hotter spark but a harder/thicker cup to prevent slam fires. If you use Tac powder either use more neck tension or a slight crimp so that the powder will burn more efficiently.navyrad8r said:i was warned by my mentor to avoid the remy primers at all costs for all gas service rifles. Federal regulars needed a litle extra caution as well, but if you uniform primer pocket and pay attention to look out for the occasional "proud" primer, you should be fine. i went with CCI, WW, wolf, and Federal regs.
cheers,
doc
Your Chrony is optimistic. Later! Frankliseo said:Old topc, but lets try anyway..,
With my custon 223 rifle krieger barrel and 1/9 tw, I loads some 77 MK with 24 grains of Reloader 15 and CCI SP at magazine lenght. Compressed load, but accuracy is good.
But my cronograph show me average velocity at 3010 fps. Is this correct or my chrony is bad?
