I think if you search on here, you will find many have shot these long range. What i gather is that most feel the BC is correct. I may have misinterpreted their post, so read them yourself. I've shot over 200 of them out to 1100 yards. The 180s and 195 are the only bullets that my 28 has fired. To me they are as advertised.
I used .750 in a 9.5 twist 7mm rem mag on Thursday and I was good to 1000 yards. Im at 575 ft.
Can you post the same numbers for the 195?
That's impressive it is stable with 9.5 twist and low altitude. I only tried stuff that works for others, this is useful.
No, I don't know.
