Re: Two OAL standards per cartridge
This is exactly what I have setup for my 300WM with 220 smks. A long load with 4831 (for close range precision shooting), a short load with 4831 (for mag feed hunting) and a long load with H1000 that has less ES than the 4831 loads when I am killing paper, and need less vertical. I would reccomend marking the bullets, not the case however. Color the ogive, forward of the bearing surface with a pair of different colored sharpies to distinguish loads. Depending on how deep you have to seat the bullets to fit the mag, you may have to change charge weights in order to keep the same velocity, and to be able to use the loads interchangabely.
