I have never heard of the Richard Graves
350gr. ULD bullet,it sound's interesting can
you give me more info about how to aquire
some of these mini-rocket's. are they solid
copper like the lost rivers or do they have
a lead core ?
I just found out that myself too.
The Excalibur is a 300 Pegasus based cartridge. I think I really was thinking of the 338 A-Square, but that has a rather long troath. I agree with your choice, theese cases wil never die.
Does the KAHN have shorter troath and sharper shoulder than the A-Square?
There may be slight differences in shoulder angle and neck length but other then that I would say they are twins by a different name.
The throat in my Kahn is relatively short for shooting bullets like the 300 gr Sierra Mk as it is only 0.275" long. Still it is plenty long enough when you have a case that will handle 120 gr of powder.
I personally do not feel the throat length increases or decreases accuracy potential as long as the throat diameter is correct for a given bullet and the run outs in teh ammo are quality.
