I used the 200 sst and the 195 gr barnes one year to take 2 deer with a 50 cal encore.I think the 8pt was at 100 yds with the 195 barnes,I lost the deer to find 3 days later,the 195 had penciled through behind the shoulder.No blood or hair when the smoke cleared I din't know which way the deer ran,we looked for a couple hours for it then.Found it 3 days later by the smell,it had gone about 75 or 80 yds onto other club land.
With the 200 sst 45 yd broadside behind the shoulder,think it went less than 20 yds,Blood every where.Complete pass through.
The 200 gr 10 mm was just as accurate but didn't try them on deer,before I sold the encore.
