With Remington rifles it is normal. Most all that I have have long throats and so will take longer than normal spec cartridges...
If you want to use the gun as a repeater you are limited by the magazine length.
If you don't mind single loading you can make them longer.
I have one 308 that I can seat Berger 185's to over 3 inches with over 47 grains of Varget... My normal 308 load is 45g Varget and the Sierra 175g smk seated to magazine length.
All because of the length of the chamber/throat.
I'd just try the SST's loaded to spec and see what they did. You can always make them longer if you want and if nothing else you have a baseline for performance...
