Has anyone tested this RMR bullet?  RMR claims the round nose has the potential to be more accurate over the RNFP:

Quote*NOTE* This is a Round Nose Bullet.  Conventional .40 180 Gr. bullets have a RNFP or round nose, flat point profile.  We have heard some raving fans discussing the accuracy of this profile and we think you will be pleased with the different nose style.  Please make sure that you adjust your seating die accordingly.

I see no reason not to use the RMR round nose types.  The theory is that pointer bullet will cut through the air with less resistance/drag...with that in mind a true round nose should fly flatter at distance.  So if you are going to shoot say beyond 75, 100 or even 150 yards you may see some examples of flatter trajectory based on the bullets coefficient and speed...Whereas HP designs were a defensive expanding design.

The reliability of feeding with round nosed designs is why they were originally produced, so they can transition from the magazine, slide forward and up the feed ramp to the chamber with less resistance into the chamber.

The TC truncated cone design also a flat point was designed with feeding properties as well, to maintain the proper tipping angle as the cartridge slides into battery.  This is why there were issues with the WNFP wide Nose Flat Point designs as the tipping angle was compromised with the wider MEPLAT.  That is also why we see Double Tap WNFP Hard Cast being seated deeper which changes the tipping angle slightly to improve feeding.  However the deeper you seat a projectile the more it raises the pressure for a given powder charge in the reduced space.

Good luck and have fun

I guess I should have added that I am very happy with the accuracy of the Hornady HAP bullets, but was looking for a little less expensive option.  I tried the X-Treme RNFP HPCB and at similar loads to the HAPs their accuracy on paper was dismal at best...  Maybe I need to play with the loads a little more, but since they were advertising the heavy plated to give jacketed like performance I ran them at 1250 fps (advertised good to 1500 fps).  Also, after finding out they are owned by Freedom Munitions I understand why Freedom loads their 10mm ammo down so low!

Maybe the 5 cent savings per bullet is not worth, but I thought I would give the RMR bullets a chance.

When working with Plated bullets, care needs to be taken when loading them.  Seat in a nicely expanded case mouth with no crimp being applied (raise the seater/crimp die at least an 1/8" to avoid the case mouth being squeezed inward).  After they are seated to depth for proper COAL then adjust to apply a light taper crimp to iron out the expanded case mouth.  Too much crimp can cut the plating on some brands.

Never use the LEE FCD to finish them as the resizing action can squeeze the casing enough to make the bullets slightly smaller.  That can be detrimental to accuracy also.   

I was using a RCBS expander die (one that doesn't bell as much but has 3 steps to open up the mouth), Redding Micrometer seat die, and Redding Micrometer crimp die.  I thought I opened them up a good bit more than normal, bullet would drop about 1/3 to 1/2 of way in, and crimp was set to just a hair under 0.430".  I'll give it another try and see if I get better results.
