Just got through my first ever batch of rifle rounds (300AAC, load workup), but I'm wondering if my wandering OAL is going to make the results meaningless.
Using brand new brass all trimmed exactly the same. Dillon 550B with Dillon carbide dies (except crimp - that's lee FCD). Hornady 150g FMJ-BTs. Crimped light into the cannelure. Set an OAL at 2.070 before I started loading. But the resultant rounds range from 2.058 to 2.080.
The only thing I've loaded before is straight-walled pistol, & my OAL is always on the money, but those dies index on the nose of the bullet where it appears these index on the ogive.
Is this par for the course? Acceptable? Am I using the die wrong somehow? Bad bullets? Set me straight, por favor.
