philipsinewe Posted May 11, 2019 Share Posted May 11, 2019 In jacketed bullets, why round nose vs. hollow point? Seems a lot of it is to do with the base of the bullet being jacketed vs exposed, and mostly having to do with comps. Link to comment Share on other sites More sharing options...
Sarge Posted May 11, 2019 Share Posted May 11, 2019 Most JHP HAVE slightly hollowed out bases which tend to improve accuracy though that’s not really critical in our games. JHP Also tend to have longer bearing surfaces which also tend to improve accuracy but I like the fact it helps me load longer for Open. They make cleaner cut holes in cardboard. One of the biggest factors for me is I only load 9MAJOR with JHP and anything minor I only use round nose. This makes it virtually impossible to mistake one for the other.

Any major downsides in using RN fmj exposed lead bottom for major? Link to comment Share on other sites More sharing options...
superdude Posted May 11, 2019 Share Posted May 11, 2019 Few JHP in my experience have slightly hollowed out bases. Zeros are the only one I can think of off the top of my head. philipsinewe, you're right about exposed lead and compensators. A JHP bullet has no exposed lead at the base and thus no lead from the bottom of the bullet is vaporized when fired. Vaporized lead from FMJ bullets with exposed bases will gradually build up in compensators, so most folks with compensators prefer the JHP bullets for this reason. JHP and flat nosed jacketed bullets have a good reputation for accuracy, and in general, tend to shoot more accurately than round nose bullets. Of course there are exceptions to this and it usually depends on which specific bullet one is referring to. Link to comment Share on other sites More sharing options...

I’m sure there are others as well Even With roundnose bullets in minor I don’t use FMJ’s. I prefer MG CMJ’s since the lead base is covered Link to comment Share on other sites More sharing options...

It takes a while, but the lead bottoms will eventually lead up your comp - and that's a lot of work to remove. Some people spray their comps before each shooting session, and then try to wipe the lead out each day - for us lazy bums, that's way too much work. I use copper bottomed bullets and relax after a match. Link to comment Share on other sites More sharing options...
zzt Posted May 12, 2019 Share Posted May 12, 2019 I only shoot JHPs out of my Open gun for both minor and major. So far my favorite is the 115 HAP. It is a tack driver. If I had a regular 9mm gun, I'd still use JHPs or good plated (like Rainier). Link to comment Share on other sites More sharing options...
OPENB Posted May 12, 2019 Share Posted May 12, 2019 Phil, for your CO guns, I like Blue Bullets. They smoked less for me than other coated bullets. Sport Pistol is the new hotness powder for coated bullets these days. Not much to be saved with plated bullets vs. jacketed when you buy 2000 or more from Precision Delta. Congrats on the 650, you’ll love it. I’ll give you some tips I’ve learned about mine tomorrow. Bob Link to comment Share on other sites More sharing options...

I only have 2000 left, so I'll have to hoard them for when super accuracy is required. I'll also have to renew a search for accurate poly coated bullets. The original Falcons and Precision Gen 1 bullets were great, but no longer available. Nothing else I've tried comes close. Now that Dardas has retired, I'll have to hunt for bullseye accurate 45 ACP heads. Edited May 13, 2019 by zzt Link to comment Share on other sites More sharing options...
Shmella Posted May 13, 2019 Share Posted May 13, 2019 JHP are prettier too. Cost is basically the same. JHP dont lead up the comp and are nice to look at. Link to comment Share on other sites More sharing options...
PewPewJohnson87 Posted May 16, 2019 Share Posted May 16, 2019 has anyone seen a difference in FPS between a RN & JHP? just curious if one might be fast then the other (same weight & bullet MFGr obviously) Link to comment Share on other sites More sharing options...
Service Desk Posted May 16, 2019 Share Posted May 16, 2019 I shoot mainly Hornadt 115 HAP projectiles and use a few RN 115's for 25 yard and closer practice. With the same load and same coal there is only a marginal difference. Link to comment Share on other sites More sharing options...
OptimiStick Posted May 18, 2019 Share Posted May 18, 2019 I was told that Jhp moved the center of gravity more to the rear of the bullet which accounts for the increased accuracy. No idea if its true, but it seems reasonable. Link to comment Share on other sites More sharing options...
