Round nose vs HP

Recommended Posts

Any insight in the pros and cons with Round nose vs Hollow point in open 9 mm Major.

I got some RMR 124 RN and the new MPR HP in 124 as well and am working up some loads to try on my Chaos when it arrives....yea I’m excited.

Any preferences or experience with either design and this manufacturer??

Thanks.......

I was able to load longer OAL with HP rather than round nose. But if your barrel is reamed for either then or shouldn’t matter that much.

You might get less leading in your comp with the HP as the base is sealed, vs the RN which has an open base.

The RMR 125 RN is a plated bullet, so you will not be leading the comp.  Jacketed RNs will.  I use JHPs and Plated bullets in my Open guns.  The only crud left in the comp is carbon.

 

The RMR 125 124 is inexpensive.  I still prefer JHPs, because they are more consistent.  You have several manufacturers who sell JHPs for under 9 cents per bullet.  I would choose one of them over the MPR HP.   You are shooting in a competition, not combat.

Montana Gold Makes a CMJ roundnose for those that you ant or need a Jacketed RN with no lead exposed.

  I like to load JHP’s in Open for a few different reasons. I only load RN’s in minor ammo so I have a quick visual reference to keep things separate.

Am with Sarge, HP for open and RN for minor. I prefer the JHP for open for several of the reasons listed above and i found them more accurate for myself .

The RMR 124 MPR JHP is a good bullet. No feeding issues with it in any of my guns and was far more accurate than the MGs I was running.

I've shot about 15k RMR 115 fmjs. Never had any issues. I love their projos. I've requested for them to make 115 JHPs. I think everyone else should email them to make 115 JHPs too!

I have had some occasional feeding issues with HP.  Switched to RN and not had an issue is several years.

I personally use precision Delta jhp. First bullet I loaded for my open gun and they shot so well and consistently I never tried anything else

Some JHPs, (Everglades V2 and Zero) have a more rounded profile than the truncated  cone shape of Montana Gold or Precision Delta.  My gun feeds the rounder profile better. Currently really liking  the Everglades 115s

Literally me!
My chaos doesn’t like certain profiles. The EG jhp is very nice and I recently switched from the 124 to the 115g.

I'm pretty happy with the RMR 124 HPs, they look strange loaded all the way out vs a conical HP, but for the price they are great and the accuracy is good too.

+1 on the EG v2 rn jhp.  They feed better than anything I've tried.

What is the diameter of the EG v2? I have ordered some of their bullets in the past and was getting .3535-.354 diameter. And was getting poor accuracy!

Just measured 5.  I got right at .3545, pretty consistently.  These have been as accurate as any bullet I've tried in my experience.

Everglades version 2 9mm hp.   Great bullet great price.   Best of both worlds a hp with a rn shape

Every gun is different. There are at least a half dozen likely suspects among top rated manufacturers and many weights & shapes from each. Keep sampling until you find something you, your gun and your wallet all agree on.

 

I usually find it easiest to settle on a weight first and go from there. At the same power factor, heavier bullets give less total recoil impulse but many find that the quicker/snappier recoil of the lighter bullets gets you back on target quicker.

 

Because of construction methods, JHP's are almost always more accurate than FMJ's. But again, every gun is different.

My gun didn't really care for the pd, started with Montana gold, great EXPENSIVE bullet, then moved to the everglades v2, but currently really enjoying the RMR 124 gr hp, accurate and maybe even a little softer shooting, not sure if they are a bit softer lead that fills the lans  more or what, and can't beat the cost. Check them out, they Just launched a new updated website as well

I put two rounds with MG CMJ on top of fully loaded 170mm mags.  I have not seen issues with feeding JHP under a lot of mag spring tension, but consider this small additional margin of reliability.

The CMJ (Complete Metal Jacket) bullets have their bottom covered with jacket, hence their name.

 

So do plated bullets, and coated bullets.  Only the traditional FMJ bullets have exposed lead on their bottom.

 

There are quite a few people shooting coated bullets in their open guns nowadays.  I do it often at practice, with no ill effect.
