45ACP: FMJ, CMJ, JHP

[Art Yeo]

All,

In all of your years of experience, which bullet type produces the best accuracy and reliability in a 1911 used for competition:

1. Full Matel Jacket (FMJ)
   
2. Complete Metal Jacket (CMJ)
   
3. Jacketed Hollow Point (JHP)
   

?

Do tell us why if you know why because it will help me consolidate my thoughts. Thanks!

Reliability = FMJ

Accuracy = JHP/SWC

That said, I've had 10-shot 1.5 inch groups at 25 yards with a 230 grain FMJ RN bullet in my accurized Combat 45 ACP (in a Ransom Rest), which is good enough for IPSC.

Isn't a FMJ, CMJ, & TMJ all the same thing?

[Art Yeo]

FMJ wraps around but the base of the bullet is usually not covered by the jacket.

CMJ or TMJ means the entire bullet is completely wrapped by the jacket.

Thanks for the info. I thought it was a manufacturer marketing deal to make their bullets sound sexy or somthing like that.

I use either Bayou or Hornady Fully encapsulated (RN jacketed including the base)

I prefer LSWCs - weren't included on choices.

[noylj]

1) JHP

2) L-SWC

3) L-CFP or L-RNFP

4) FMJ-FP

5) FMJ-RN or CMJ or L-RN

6) Plated, including TMJ

Also, ensuring that the JACKETED bullets are groove diameter to 0.001" over groove diameter improves accuracy.

Of course, unless you are working at <3.0" at 50 yards, it probably JUST DOESN'T MATTER.

Bayou Bullet for me. 230 gr RN

i agree, SWC should be on the list, it would top it
