What is the difference between the Rem Unibody plastic case fold crimp hulls & the STS plastic case fold crimp hulls?
Looking through the newest Lyman book & see these are listed separately.
Is this just old irrelevant data & are recipes interchangeable ? Google is no help on this one.

There were the old ribbed type, which later became smooth, Some said "Skeet" and some said Target. The latest say STS PREMIER on them.

FWIW I load them all the same.

I load both Remington Gun Clubs and STS Remington's the same.

Im working with what I have which are STS Hulls, W209. SP20 , WAA20 or Fed 20S1 wads,International, longshot, Unique & Universal Powders .
UNI = 17.5 LS /W 209 / Waa20 @ 1166 / 10600
1 oz loads <
STS = 16.5 LS /W 209 / SP20 @ 1199 / 10400

The Unibody hull doesn't list a 7/8 oz at all.
While for 7/8, the STS Hull utilizes W209s with the same wads ,International, Longshot, Unique & Universal powders with the respective FPS variations between field or target loads.

Lyman Shotshell Reloading Handbook 4th ed, page 234, has 7/8 oz loads for the Remington Unibody hull:
14.0 Unique, W209, WAA20, 7/8 oz for 1162 fps, 11,300 psi.
