In fact, the Speer 13 manual lists, I believe, 27 or 28 grains of W 748.... I will have to double check that....


There's the key to that 29 grs of 748 used in that rifle with the "worn" throat, that's like more freebore, the same exact thing Weatherby did to achieve his high velocity figures without excessive pressures...lots of freebore.

The AR15 was not designed to take the same pressures that bolt rifle can be reloaded too.
But even 30 grains with 55 grain bullets in bolt guns have not been any problem...

and that has been in Federal, Winchester, Remington, Lake City and WCC cases....

primer I normally use is Winchester Small rifle or Remington 7 1/2 primers...


29 grains of W 748 with a 55 grain SP Rem Bulk really tightened up the groups in a 223 barrel that was getting pretty worn at the throat...

This is what I have heard. But Im curios of what pressure the little case is under. They who use it, gets around 31 grains of powder in it.

I could buy into that if you had one with a deep enough throat and fast enough twist to stabalize let say a 75 gr. bullet. roger
