just use cast bullet data.
i never seen any difference between the two in target speed loads.
i would pretty much switch back and forth with impunity between the two, until i started making my own cast bullets.

 

Thanks would anyone have some loads in 38 special using Universal, Unique, SR 7625 or N330 and what OAL?

 

I have us



If you look in the old manuals, the flat ended wadcutters are listed as target rounds, usually swaged bullets that lead badly. My old Speer manual lists 5.1 grains of Unique for 981 fps from a 6 inch Ruger Security Six.

They also list a much lighter load of 3.4 grains intended only for the semi automatic Smith and Wesson target pistol.

I have them and have loaded various other brands of them or lead for over 50 years. The Berrys you can shoot up to 1,250 fps in a 357 but cannot get them much over 900 or so in a 38. My pet load has always been 5.0 grains of Unique, regardless lead, copper or coated.

This is the exact load I use with the 158 grain SWC. At that level 4.5 grains is max and 5.0 falls into the Plus P category. Does not matter to me, I collect Smith and Wessons and shoot them in 50-60 year old guns. The lighter 148 grain bullet would be even lower pressure and pretty safe in my book.

My opinion is the 5.0 or 5.1 grains of Unique is about the perfect load for that bullet. It work for target, or plinking or game or even defense.

Crimping is at the front or first groove behind the front of the bullet. That means about 90% of the bullet is inside the case. I load them both in 38 Special and 357. I am also loading a few into the 38 Short Colt, just for grins. I am using a different powder for those.

Here is what Hodgen says with Universal. That is from a 7.7 inch test barrel.

Good luck. Give us a report on what you decide and how they work.

 

universal will overlap the unique loads.
if your shooting bulls-eye you can work down towards 3.0 with either one.
the 7625 is too slow for target speeds.
i'm not sure on the VV powder,,, it isn't real common as a handgun powder around here, and is mainly only used by the target rifle shooter guy's that shoot Berger or custom made stuff with their jackets.

 

Highjacking the thread with one question. I cannot get Unique or Universal. Any one using Winchester 244 for the low pressure handgun rounds, 38 special, 44 special, 45 acp, 45 Colt? it is next to Unique on the burn rate chart. And a powder I can find at Bass Pro.
