I am Very satisfied with IMR4320!! I could have pushed both ending loads a little more, but will stop with these: 150g SP and 51.5grains of powder=2900FPS
174g RN and 49grains of powder=2650fps

These are very close to max loads, and are WAY Minute Of a Deer

Next up will be 52-55grains IMR4320 and 100g 32cal Pistol Bullets 8)

Just curious - how does it shoot without the Lee FCD? IMHO, they are neither needed nor desirable for bolt guns.

It has been my finding, especially in the military bolt rifles that all have looooooooog throats that the use of a Lee Factory Crimp Die DOES INCREASE ACCURACY over the same load NOT CRIMPED.
