Up to recently, I've rarely used the SST on my CZ527 223. Always considered the trigger too far forward when set. Whilst shooting across a valley the other day [off Quad Sticks with back against stone pillar] I decided to give the SST a try. All I can say is, I've never shot better! Trigger breaks like glass and was nowhere near as uncomfortable as I recalled. For safety reasons, I set the trigger just before each shot, and had 3 x 200m and 1 x300 rabbit/s and a 120m pigeon in 5 shots. Conditions were ideal....bright with little wind. Took my rifle to work this morning and tested it at 200m, again using the SST. For the first time ever, I had 3 touching holes at this range. Have had them within just over an inch at 200m, but never touching. I'm using 24g of Benchmark with 55g Blitzkings and needless to sat, they're superb. For whatever reason, 55g V-max do not group as tightly.
I'm aware that some folk don't seem to get on with the SST and prefer to lighten the standard trigger. I have the latter down to just over 3lb, but reckon I'd do better using the SST for those longer ranger shots. Happy to keep the standard trigger at 3lb for general field use. I'm interested to hear from other folks who use the SST and from folk who, for whatever reason, don't.
