I shot 9 deer & a coyote last Fall with the regular 250 grn SST M-L bullet/sabot combination. There were all 1 shot kills & fell within sight. Most were soft tissue shots(pass-thru), just behind the front leg. They shoot very well in my Knight & I use about 115 grns of B-209. I hear different things about the SST's but myself & the partner like them. Of course you have to put them in the right spot too. I was hunting 2 States, & one location has an over load of deer with plentiful anterless permits.
