Open Gun bullet weight .38 super

So I am just getting in to open division and was wondering about bullet weight.

what are your experiences with bullet weight

is heavier better or lighter better?

i realize that for a open gun you need the comp to do its job, so is there a good middle ground to shoot for?

 

or some good starting reload data?

124/5gr, work a load up that runs your gun flat and then load a bunch of ammo and learn to shoot open

this, best advice you could get

115 gr will take more of a slower powder but have the benefit of more gas. Your comp may very well work more effectively with a slower powder. Experiment with both 124's and 115's. Be sure to watch out for the powder load difference between the two. Good luck.

At 2016 Open Nationals, 86% used 121-125g, 12% 115g

 

Guess that answers that question    :)

 

I would have guessed that the "experts" would tend towards the lighter bullet,

which I tried first when I started in OPEN 10 years ago.

 

Didn't like the lighter bullets - switched over to MG 124 JHP's and have never

looked back.    :)

I have been using MGB 124gr JHP for a long long time now and they have done well.  At one point a friend and I compared JHP vs Jacked round nos and found the JHP gave us a faster speeds than compared to the round nose.  This was in Colorado (so ~5000 feet) I have not completed the same test at sea level, maybe others have.
