cache Posted July 8, 2011 Share Posted July 8, 2011 I getting ready to order some new bullets, and I'm wondering if there is an accuracy difference between these bullets. Link to comment Share on other sites More sharing options...
DougCarden Posted July 8, 2011 Share Posted July 8, 2011 Depending on the load....... A load that is normally a one hole load at 35yds with a jhp will blow out to 3-5inches at 35yds by replacing the jhp with a fmj. This is one example of a 9mm load. When you get to heavier bullets like the 147s the FMJ/CMJ will normally shoot pretty close to JHPs. In the 115-124 gr bullet weight in 9mm the jhp is much more accurate at distances at 20yards and out. It just depends on how much accuracy you need/want, and what you are trying to accomplish. Hope this helps, DougC Link to comment Share on other sites More sharing options...
gng4life Posted July 8, 2011 Share Posted July 8, 2011 One other thing to consider is that with FMJ, you are going to have exposed lead on the bottom so that will usually cause more smoke. Also, very much agree with Doug above! Link to comment Share on other sites More sharing options...
noylj Posted July 9, 2011 Share Posted July 9, 2011 Since you can coat the base of a bullet with wax and, when retrieved, the wax is still unmelted, I have no idea how the lead could be melting considering its heat capacity and time of exposure. Then again, I don't notice smoke from my lead loads, so what do I know. I like JHPs because they are almost universally accurate. I don't like FMJ because they are "boring" to me. I would much rather work up a cast SWC load than load those round nose boring bullets. I rate them as just a little better than a L-RN bullet. However, a FMJ-FP is certainly of minor interest. At least there is some flat meplate. Link to comment Share on other sites More sharing options...
Foxbat Posted July 9, 2011 Share Posted July 9, 2011 As the general rule, the JHP's will be more accurate. Just how much more - depends on a gun. I have one where they are close, and I have another one where there is a difference of a factor of 3 or 4. Another considerations - some guns don't like JHP's - one of my open guns will fail to feed it once in 200 rounds or so. So for that one I use CMJ's with very small, practically insignificant loss of accuracy. Link to comment Share on other sites More sharing options...

Canuck223 Posted July 13, 2011 Share Posted July 13, 2011 Hollowpoints are longer than comparable weight FMJ's so there's more bullet for the rifling to stabilize. The final stamping operation in thier construction is at the nose, instead of the base as in a FMJ. An imperfection in the final operation of making a JHP still tends to result in a bullet that flies straight. (If you want to try an experiment, grab 10 cast lead bullets and a file. Cut a groove in the tips of 5, and the bases of the other five. Fire for effect) If your gun feeds them well, I'd be surprised if you didn't notice an improvement in accuracy.

Aircooled6racer Posted July 14, 2011 Share Posted July 14, 2011 Hello: The CMJ makes a slightly bigger hole than the JHP's. I like the JHP since I need all the accuracy I can get Thanks, Eric Link to comment Share on other sites More sharing options...
Bansheex Posted July 14, 2011 Share Posted July 14, 2011 I started out with the 115gr JHP's but like said above, I started to get FTF in my 170 mag. The stock mags seem to work OK. Maybe I need to try a different spring in the 170? Link to comment Share on other sites More sharing options...
