Hi

Maybe this is a reloading question, but I've been reloading both in lead and FMJ/JHP form. But as yet haven't come to a conclusion as to which one is more accurate. Now it’s time to buy more lead and I can’t decide if I should buy a box of both again.

What do you guys think?
 
The point means little accuracy wise. The base is what is important. In any case, jacketred bullets are far too expensive to shoot regularly. Work up a load using cast or swaged bullets.
The difference between an RN, WC and SWC bullets is mostly seen in the hole on the target and is more for ease of scoring than anything else. WC's and SWC's cut a cleaner hole. RN's tend to leave a less precise hole.

What caliber are you shooting?

9mm. I've been pistol shooting for just over a year now and my groups are getting better. As others have stated before, jacketed bullets give better groups. But for cost reasons I want to shoot more cast lead bullets. So far I haven't notice much of a difference between RN & conical bullets when both are of the same type (jacketed or not). But that could be me. So far, on a good day shooting lead my groups are around 80-100mm (3-4 inches) @ 10m. With Factor FMJ I can cut that in half.

Basiclly Im looking for ways to improve my groups.
 
You asked the wrong question : it is not round nose versus conical , it is jacketed or lead bullet.
Lead bullet are not the best choice in the 9mm because of the velocity used in those rounds. In most 9 mm, the type of rifling and twist used is not the best for lead bullet. If the lead bullet ammo you use is loaded too hot , the bore will get leaded in short order and accuracy will suffer.

9 mm bore do vary from .355 to .357. By using the right bullet and refine the powder charge, you can get lead bullet to shoot. If you do not use the right bullet sized properly, you will not get good accuracy with the 9.
My experience with the 9 mm, is that most of the time, a jacketed bullet is the best choice.
 
You should try the Frontier CMJ bullets from Marstar (or other sources). Way cheaper than jacketed, and no leading since they're completly copper plated. I've been using those for both my .45 and .44 for years now without a single problem.

For the bullet shape : I usually shoot Round Nosed .45 230 grains, but my supply ran short and I had to temporarily switch to 200 grains Truncated Cone bullets. My Para-Ord never had a jam or failure to feed/chamber when using round nose, but I experienced many jams with Truncated Cones, I would say 4-5% appromately (five rounds over a 100 rounde box), with various OAL.

Sometimes a gun's feeding ramp isn't flat nosed bullet friendly. My Para had hard time with them, and my Norinco NP-30 had trouble with both RN and TC.
 
The Frontier TC are good, accurate bullets.
Pushed too fast in polygonal rifling guns ( Glock ), some shooter experienced heavy fouling. Every bullet has a speed limit. Since they are cast, plated bullet, the copper might be softer than a gilding copper jacket.

When chosing a SWC bullet, check also the diameter you are purchasing. Wolf sell .45 ACP lead SWC in .450, .451 and .452. If you have .452 bullet and experience jam, go lower. If poor accuracy and leading, go to the next diameter.

Round nosed are usually the best for reliability. SWC are the way to go for paper punching.

You can purchase SWC jacketed bullet and have the best of both world. ( Hornady SWC have a rounded shoulder and they usually feed better in gun that have a problem with lead SWC sharp edge)

Experimentation is what make reloading fun !
