laker252,
Couple of thing that I do may help a little:
1. Keep sabot/bullet in shirt pocket, under coat,to keep the plastic sabot warm= easier loading.
2. Try the T/C 45/250gr Shockwaves. Same bullet as SST's but understand they load easier than the Hornady sabot. Must be a little thinner plastic side walls. Have some, but have not tried yet myself.
3. In cold weather,I use a smear of BoreButter on some of my sabots that are tight loading. It helps...however,you would want to try it to check for any impact change. Some of my front stuffers will shoot a little high with the BB on the sabots. :grin:
