I use 100gr of loose RS with a T/C SST. Also had good accuracy with T/C blk mag sabots 240gr. I have an old stainless LK-93 and still use a #11 cap. When I have searched various forums, the 300 grain XTP seemed to be the most popular load with 90/100 grains of powder. I've been wanting to try the Speer Gold Dot bullets, due to its fast expanding bullets. The SST may be good for longer ranges, but I'm not sure how good it expands.
