rbuck Posted August 10, 2017 Share Posted August 10, 2017 I cant decide if i want 115g JHP again or if i want 124g to try out. The only problem with going 147g JHP are that they are super expensive! Link to comment Share on other sites More sharing options...
mro111lland Posted August 10, 2017 Share Posted August 10, 2017 Well let's start with what you shoot and what class u shoot if any Link to comment Share on other sites More sharing options...
Hi-Power Jack Posted August 10, 2017 Share Posted August 10, 2017 In OPEN, there's no advantage to the 147's . Most common is the 124's because they're easier to load without the powder spilling out of the case. The 115's take More Powder to make Major - so the powder doesn't leave a Lot of Room for the bullet. BUT, some people really love the 115's (Or 121's as a compromise) - I've been shooting 124's for nine years - but thinking of going back to 115's when I run out of my Pre-Election horde of 124's If you're not sure, I'd say start with a real good supply of PD JHP's 124's and see if you want to stay with them after you get some experience Link to comment Share on other sites More sharing options...
Aircooled6racer Posted August 10, 2017 Share Posted August 10, 2017 Hello: Stick with 115's. Use a good powder like HS-6 or Silhouette. If you go to 121's or 124's try some Winchester Auto comp and HS-6. I am testing some 121 Montana Golds right now with HS-6. Not sure if they are any better than my 115 load. Thanks, Eric Link to comment Share on other sites More sharing options...
S&W686 Posted August 10, 2017 Share Posted August 10, 2017 In my Open Gun I shoot Montana Gold 115 JHP with Winchester Autocomp. The gun shoots very well with this combination. Link to comment Share on other sites More sharing options...
zzt Posted August 10, 2017 Share Posted August 10, 2017 (edited) I go for consistency. I want the dot to track straight up and down with no squirming, and return to the dame place. I pick the powder and bullet combination that makes that happen. I cannot figure out why that is. For example, with one particular bullet loaded to 172PF, HS-6 produces the least felt recoil and slightly less muzzle rise. However the dot squirms. Using WAC or Silhouette, it tracks straight. BTW, I would not bother trying the 147 unless you are trying to make Major without the excessive pressure. Edited August 10, 2017 by zzt Link to comment Share on other sites More sharing options...
ar15rick Posted August 15, 2017 Share Posted August 15, 2017 i have tried both the 124 and 115 precision deltas. I personally like the 115 with HS 6 and also AA#7. Both will get you good results and what I like is that the gun returns back to its original state fast so you can shoot your follow up shot. The only problem with AA#7 is that is very dirty. You will probably be needing to clean your gun more often. So the way I can explain it for both bullets is that the 124 might be a little softer on the hand but might have a little more muzzle rise. The 115 feel a little more aggressive on the hand but with the amount of powder that I am putting in, it makes the gun shoot flatter and some back to its original state quicker.

Jerry Anderson Posted August 15, 2017 Share Posted August 15, 2017 I'm using 115's with HS-6 in one Open gun. A little shorter slide-barrel combination. In my full size gun i use 124's and 7625. Both are tuned for the gun port combination. Link to comment Share on other sites More sharing options...

Now that I am shooting an Akai V8 stroked, I switched over to 9.7 of HS6 with 115gr precision delta jhp. It's even flatter than what I used with aa#7 and isn't as violent in the hand. I seriously think it's because of the gun and how it works. My old gun was an sti Frankenstein with a Brazos Thunder comp 2 with no popple holes.

cferree Posted August 16, 2017 Share Posted August 16, 2017 (edited) I use HS-6 now instead of Autocomp with 115's. The gun is a slightly modified Match Master. The AC load was flatter, but extremely violent. I switched HS-6 (9.0 w/115 MG), and it calmed it down. It's not as flat, but the dot tracks consistently.

I started with 9 gr HS6 and 115's 10 years ago - loved it, but used to throw powder during the reloading cycle. Switched to WAC and 124's, but the HS6 / 115 load was nicer to shoot Link to comment Share on other sites More sharing options...

Get something that works, and don't mess around trying to find the holy grail. Just load a bunch of them and practice practice practice. Link to comment Share on other sites More sharing options...
jmaples71 Posted August 18, 2017 Share Posted August 18, 2017 I prefer precision delta 124s. Little cheaper than Montana Gold but good bullets. I use them for my production load as well. Same powder - CFE Pistol. Just change powder amount and seating depth. Limited variables. Link to comment Share on other sites More sharing options...
Kimber76 Posted August 19, 2017 Share Posted August 19, 2017 Why JHPs over FMJ round nose when loading for 9mm major? I'm going to be switching to open soon and was curious what the advantage is over FMJs. Link to comment Share on other sites More sharing options...

I don't know because I have never shot FMJ out of my open gun so I can't really tell you but I just went off of what the rumor stated.

My question now would be is it because of the higher velocity of 9mm major that the JHP is more stable? If not than why is everyone not loading JHP across all divisions? Just a thought.

MrPostman Posted August 19, 2017 Share Posted August 19, 2017 JHPs have more bearing surface than FMJs. Bearing surface = part that touches rifiling. Which is the reason why they are considered more accurate. Sent from my SAMSUNG-SM-G935A using Tapatalk Link to comment Share on other sites More sharing options...
Gooldylocks Posted August 19, 2017 Share Posted August 19, 2017 There are multiple reasons for JHP. Comp leading is the biggest, the exposed lead base of the FMJs will cause the comp to lead more than the fully encapsulated bases of a JHP or CMJ. Accuracy is a minor added benefit for JHPs, as they are generally the most accurate bullets built. The reason they aren't used by all shooters across all divisions is simple: shooters are cheap.

zzt Posted August 22, 2017 Share Posted August 22, 2017 Amen to that. Digging lead out of a comp is a PITA. If for any reason you cannot use JHPs in your Open gun, try TMJ or plated. I can't make a blanket statement about JHP accuracy. I think it may depend on the caliber and the gun. For instance, 180gr Nosler JHPs are the most accurate in my bullseye gun. I have two 40sw guns that prefer Rainier 155gr plated over MG 155 JHPs, and by an appreciable margin. Link to comment Share on other sites More sharing options...

Frugal or not, allowing your equipment to cost you precious points or places at a match is more expensive than the extra cost of the bullets. Match fee 200, plane ticket 300, Hotel 80 per night...Sent from my SM-G930V using Tapatalk Link to comment Share on other sites More sharing options...
digi531 Posted August 24, 2017 Share Posted August 24, 2017 Hello, I've settled on JHP 121 gr. several years ago. To me, they seem to fit nicely in the middle, between the 115 and 124 with the JHP design being very accurate and the cleanest for the comps.
