Selecting a bullet
Depends on what you are trying to achieve. I have two goals for my Grendel.
My primary purpose is to have a very accurate long-range semi-automatic rifle
I am using this rifle to compete in the International Tactical Rifleman's Championship.
For this purpose I want a bullet with a good BC, heavy enough to withstand difficult wind conditions
and easy enough to spot a hit on a steel plate 500 yards away.
For this purpose a 123 grain bullet, travelling 2600 fps is my choice.
Power factor of my long range load is just around 310 (bullet weight x velocity)
If you are going to use the Grendel for shooting major power factor in practical rifle competition
you need - as per current rules of August 2006 - to make a minimum power factor of 320.
These loads are definitely stout, but you can achieve it. You can either shoot a140 grain bullet
at 2350 fps which would be safe. It might be possible to push a 123 or 129 grain bullet fast enough
to make major, but I haven't gone there yet. Bill Alexander warns you might blow a bolt doings so.
I will probably find out soon the way this rifle is coming to good use.
I'll probably use it for varmint hunting before long, in which case I'll probably shoot aHornady 95gr V-Max bullet around 3,000 fps. It's a very safe load with a power factor of 285.
