Well - I did a search in the Gun Forum and read comments on the NEW SST vs Old vs this and that. The bullet is obviously NEW as it is now a 300gr vs a 250? I like the bullet weight and the looks of the spitzer. Appears on the surface it should be a great round? Don't care much about 200 yrd.
150 Yrds - Yes - that is very doable shot with the correct set up in 12 or 20 gauge.

Don't recall reading where anybody HERE actually ran this slug thru a gun(s) to see actual field results out to 100+ yrds.Thats what I want to Read and obviously find out myself thru field tests.

I'll run the 2 boxes I have thru my 870 and maybe a few rounds thru my 500 to see how they fly.

After decades of shooting slug slinging 12's of various configs the 5 biggest problems seem to be;plastic fouling after 3-4 shots,hot barrel vs cold,loose barrel,improper scope mounting,damn gun don't like the bullet. Oh Yea - and the guy behind the butt plate pullin the trigger.
