Re: nosler 6mm 105 BC?
Got a chance to play with these today. And as suspected they don't perform up to the claimed bc. Here is what I found.
Shot out of a Rem. 700 6 mm Dasher 24" barrel suppressed with a SN-3 3.2 - 17 X 44 moa/moa (iphy/iphy) as is the dope. Used Horusvison TRAG for data.
Velocity 2911
bc .593
zero 100yd.
alt. 1120
temp. 55
bp 28.31
rh 78%
scope ht. 2.0
All come ups are in IPHY.
BC Chart ----------- observed data
500 8.7 ------------ 9.5
600 11.8 ---------- 12.5
700 15.1 ---------- 15.5
800 18.7 ---------- 19.5
850 20.7 ---------- 22.0
Despite the difference in bc they shot very well, which is really what matters. Held sub moa at every distance, the wind seamed to affect them more than I thought it should, but that is usually the case. Wind was 6 to 8 mph at 7 to 8 o’clock and my range is kinda funky because of tree rows.
I bought 500 and don't regret that at all, after reflecting on the data they really aren't that far off, probably within margin of error for input and trigger puller. I'll shoot more of them.
