That is a good question. Let me start by saying I have not heard of RMR bullets. Generally, bullet weight and powder charges go hand in hand. From there, it can get a bit specialized. Many of the Hornady XTP bullets are what we would call a "truncated cone", meaning the side of the bullet is 90 degrees from the base, and at one point on the ogive has approximately a 30 degree angle to the hollow point, giving it a sharp shoulder. The same weight and caliber Speer Gold Dot bullet has an arc to the profile more like a rifle bullet. Bullets with a truncated cone (and this includes the semi wad cutter type target bullets) may have to be seated deeper in the case to facilitate feeding and chambering. In a pistol case, you are generally using a powder with a fast burn rate, and if you seat a bullet too deeply with a particular charge, chamber pressures can increase significantly. When I use XTP bullets in my pistols, I use the data given in the Hornady manual (Powder charge and seating depth for a particular bullet), and that will ensure proper feeding and chambering as well. Another factor in bullet seating depth is what will fit in the magazine. I do own an old "Star" Spanish 9mm that will NOT chamber anything loaded with XTP bullets. It will shoot the traditional 115 Gr FMJ bullet all day.
You will notice in your manuals there are data for cast lead bullets as well. The "plated" bullets available, as well as "coated" bullets will use cast bullet data. These type bullets are meant to reduce or eliminate leading in barrels, and should be loaded to velocities meant for cast target or plinking rounds. When Rainier Ballistics was still in business, (plated bullets) their website only advised loading to cast bullet velocities. Berry's Manufacturing, another maker of plated bullets, will show a "do not exceed" muzzle velocity on the box label. Other than that, they do not provide data for their bullets. I hope this helps.
