Both lengths functioned well in my MXLR. Same load, same POI. I haven't measured my brass since I have shot today, but I have noticed that after shooting factory brass it tends to be around 1.895 and 1.90 after resizing. It will be interesting to see.
The shorter case length is to accommodate the longer Ogive of the FTX bullet which also makes the projectile itself longer too.Are there different factory loadings in terms of bullets? I read in the 450 section that the factory brass loaded with the gummy tips was shorter than the solid flat nose 350 grainers in order to get the correct OAL. In other words the gummy tips of the same weight are longer (due to the plastic tip) than solid bullets so the brass would need to be shortened accordingly for the extra length of the bullet.
