Description
These trays hold 50 cases each, and are broken down into sizes to accomodate a range of case heads. An “S” in the tray size denotes “shallow”.
Typically shorter pistol sized cartridges would drop all the way into a normal tray and be very hard to remove. Thus, shallow “S” trays are used with shorter cartridges. For instance a .45 ACP has essentially a 30-06 size case head, but would drop all the way into a #5 tray, and would be very hard to retrieve. So one would want a ‘5s’ for reloading .45 ACP.
The same could said of 5.56 and 9×19: a ‘3s’ tray would be required for 9mm, or the case would drop all the way into the hole of a standard tray and be hard to retrieve. It’s worth noting: sometimes one can get away with an S tray when loading the shorter rifle cartridges: a ‘3s’ will work ‘ok’ with 223/5.56. However with 308 a 5s would be bad (good chance of the 308 case tipping over and spilling powder).
Again: I use do 4s trays for 6.8 SPC, 40 S&W, and even 9×19. However a 308 or 30-06 would tend to tip out of a ‘5s’ (not recommended to use a ‘5s’ to hold a standard rifle cartridge).
Bottom line: sometimes close is good enough. Remember I use both 3 and 3s with 5.56/300 BLK. The 2 gives a tight fit, but the 3 is good enough too (so I didn’t bother to make a size 2 to sell here). I use 4s for both 9×19, 40 S&W, & 6.8 SPC. Or in otherwords you can typically utilize a slightly looser fit and be just fine and can sometimes get away with a shallow tray on a shorter rifle cartridge. Just don’t expect to use a shallow tray on the 308/7.62/243/6.5CM and larger rifle cartridges.
