RMR 55grn FMJ load question...

[tomlikeaidp]

Does anybody have any experience with RMR 55grn FMJ's? I bought a few hundred of these and loaded them to my old tried and true Hornady recipe with terrible results. I know all rifles are different and that I should do a full work up and blah blah blah... I'm just curious if anybody has had any success and if so, with what. Any info helps.
Thanky Thanky!

I noticed the cannelure is a bit higher on the RMR compared to the Hornady. I loaded a bit long to accommodate. I'm guessing that's probably what's throwing them off.

ive had to load rounds and disregard the cannelure before. this was with .308win loads and original winchester silvertips

Are you shooting them from a bolt gun or a semi-auto? From a bench with bags? Really curious as I was thinking of ordering some also. Also what size of groups are you getting from the hornady's?

Different guns like different bullets and different powders. There are a few bullets that do well in almost all guns, but they still may not be optimum in more than a few.
All bullets, even the same weight, vary in ogive and meplat and loads must be worked up from start.
Are they jacketed or plated? Are they the same diameter?
You also have to shoot the Hornady on the same day to be sure it isn't you or the gun.
