I tried the MG 115 & 124 CMJ's in 3 of my 9major open guns earlier this year.

Accuracy was not acceptable in these guns.

 

Definitely shoot groups with them as part of your load development.

Accuracy is exceptional with MG 115 & 124 JHP's in all of my open guns.

Finally had the time to test WAC vs 3n38 side by side with mix brass, MG 124 round cmj. Did a load ladder and picked the loads that made 170-173 power factor for both powders. Then loaded 200 rounds of 3n38 and WAC

 

Ended up with:

 

WAC 7gr  For 172PF

3n38 8.5gr for 171PF

 

accuracy was almost the same supported and free hand 15-20 

 

bill drills at 7 and 2 shot drills at 10.

I had 3n38 faster on the timer and has a smaller group over WAC so the question is will I switch...

 

yes, but I’m setting up an ammobot at the moment and I’m not sure it will manage to load 3n38 without making a mess. So I’ll start loading WAC and finish my 8lbs then try to tune the ammobot to load 3n38 if not I’m stuck with WAC

From my reading here, the 3N38 and the 115 grain bullets is The Best Load.   But,

I prefer the convenience of NOT having powder sloshing all over my SDB and

bullets not separating from the case when being jammed into the chamber    

 

Hey Jack,

 

I was trying to read the same thing about 115 grains and 3N38. Since I am reloading 38 Super Comp, grain spillage is not an issue, but wanted to pick your brain about the general consensus regarding a good load. I already have a great load for 124 grain MG bullets, but they are hard to find and I just purchased 16k from MG yesterday. So I am hoping you can provide some form of assistance with amount of 3N38 for the 115's. Thank you!
