Well I have to say I'm as sore as I've ever been after an afternoon of shooting. I for some reason took the following:
Two Encore Frames, 12 gauge SST 24" slug barrel, 24" 375 Winchester and my 28" 9.3x74R to the range...this will be the first and last time I take this combo. I'm not a small person and it took every ounce of my 290 lbs to not flinch towards the end of the session.
Slugs as follows:
BRI's were mainly for sighting in with one three shot group at 1.195" CTC, most were much larger and this was at 50 yards. I found this load to be pleasant to shoot but not as accurate as some of the others.
Winchester Platinum 2-3/4"...at 50 yards it shot a 5 shot 1.702" CTC group and was noticeably harder on the shoulder. Did not shoot this at a hundred and will shot more in the future to see if it performs better with a cleaner gun. I tried to keep it clean and cool but when you're in a small hurry because of the range time you do your best.
Lightfields at 50 yards weren't worth mentioning around 3.5" five shot group at 50 yards. These didn't kick as bad as I thought they were going to. Full 1 ounce slugs!!
Hornady SST's 300 grain sabots. First let me say I see why they are going 1900 ft/sec. (this is what the box says) they kicked me more than anything else has. But they are worth the punishment. Groups at 100 yards were printing 4" higher than the others at 50 yards, you could tell the added velocity. 5 shot group at 100 yards was 2.093" and 4 of those were 1.716". I ran out of shoulder at this point and switched to my 9.3X74R...not that this was much nicer to shoot.
I will shoot the Winchester Platinum tips at 100 yards along side the SST's to see what the difference is. I'm leaning towards the SST's because they are faster and cheaper (which suprises me). I didn't get a chance to shoot the Winchester Partition Gold and the Remington copper solids but will in the future.
Hope this info helps.
