Yes. Adjusting OAL is a very important procedure in finding that perfect load. I start close to the lands and work back (shorter) until I find the sweet spot. Starting long gives me only one way to travel as opposed to starting in the middle.

i load my 308 target loads to engage the rifling - and in a 30 cal that is way, way out there (most chambers are still cut to accomodate the 220 hornady round nose)...

as steve does, i start at the lands and work back for most loads. in target loads that are loaded single shot, i engage the lands. in some guns i start at the lands and work back until they'll fit in the magazine. just depends - but 2.84 shouldn't be much of a stretch to achieve.

kennedy,

Since you have a Remington, with throats "way out yonder", load your ammo at the longest OAL that will feed thru your magazine, and then play with various charge weights. Makes a lot more sense than sticking with a charge weight and playing with varying OAL's.
