Will a light loaded 38spl 158swc with 3.2gr bullseye shoot out of a 6" 357 mag for plinking? I loaded these easy for my wife and her 642 short barrel. I have a new to me 357 mag 6" GP100 to play with and I would like to use that ammo.
Thanks.

yes it will work.

That's more of a mid power round but fun to shoot just the same.

I have a LEE 0.5cc dipper that is modified to scoop 3.0 grains of Bulls eye and the wife really liked to shoot this round. Worked well in her S&W 66 w/4" brl.

I've used 3.0 grains of Bullseye and 158 SWC for years. It does about 780 fps out of a 6" so your's is probably breaking 800 fps from yours.

Thanks, I'm gun shy about the bullet getting stuck on the way out. I had one stick in a 1.5" 642 barrel once because I was trying to use AA#5 on a short barrel. It only takes once to lose a couple fingers and I want to keep mine.
Thanks Again.

Is there any difference between data for the types of base of the bullet?

I have some of the Dardas ".38 Caliber 158 Grain Semi-wadcutter Bevel Base 0.357" Diameter" which just came in the mail. Does the bevel base matter?

I see that load data for Bullseye with a 158 SWC is minimum OAL 1.44 and max load 3.5 grains. I saw some other data suggesting starting at 3.2 grains of Bullseye with this load.

I already have the cases primed and belled, so I'm ready to drop powder, seat, and crimp.

This is not a starting point. This is Mid level.

These are the velocities I got out of a 6" 357 with 148's and 158's, with bullseye.

Your load is lighter than what I used.

Colt Python , 6" Barrel

I checked the Hornady and the Lyman manual, and for 158 grain lead they both recommend starting at 2.8 of Bullseye. Interestingly, the Lyman (an older manual) lists 4.2 as the highest charge, whereas the latest Hornady manual says that it is 3.7. Would this be because different bullets are listed, even though they are all 158 gr lead? In the Hornady manual they list the same load data for all three bullet styles of the same weight.

I'm getting confused. Can you generally use the same load data by weight for lead rounds?

I do. Maybe if I had a pressure gun I would notice something, but I will drop in a 158 LSWC, LRN, LFP, over the same charge and I don't notice any funnies.

Looking at the lyman manual, they show pressure differences for different lead bullets, the only difference being the shape.

Heck if I know.
