after dropping my AAC-SD in the LSS...love it but did find something strange. Shot 2 3/4" 5 shot groups w/ GMM 175 SMKs which is pretty standard for that load, then i went to the rest of my 178 amax/ Varget handloads (had 20 left from previous batch)...these loads have always shot 1 big ragged hole @ 100 yds but after changing the chassis i shot 2 5 rnd groups, and a buddy shot 2 5 rnd groups and the best group was 1.5" and the avg was about 2"...thought something came loose on the rifle but just to check i loaded in 5 more 175 SMKs and shot 5 rnds touching each other...not sure how changing from my old B&C to the LSS could have that much impact on my load development but looks like i need to work something new up
