Case in point,
we spotted elk at 1100 yards this year. Neither Daughter #1 or her hubby had ever taken an elk and none of use were prepared for a shot that long.
We closed to 476 yards, at an altitude (~8500 feet) and wind conditions (essentially none) where Daughter's .308 Win/130g TTSX @ 3045fps MV
would have been adequate. While would have been quite happy to take the shot, Daughter #1 was not comfortable shooting at that range. By the
time we closed to her comfort range the elk were gone.
Granted, I used this event as an excuse to get her a .270 Win and develop a 150g LRAB load that delivers elk-killing velocity and energy
(2000fps and 1500fpe is my rule of thumb)
Your rule of thumb is
1500 fpe.... 130 ttsx 3045mv would not deliver that at 476 yds...,yet you say you would be happy to take the shot.
If manufacturer claimed BC for 130ttsx can be relied on, you would have about 1360 fpe./ 476 yd
However tests on Barnes bullets show real world BC can be below published numbers in some cases by well over 5%
which could potentially bring energy down to around 1300 fpe / 476 yd. (8500 Alt..)...or 1243 fpe / 476 yd. ( 7000 Alt.)
Daughter #1 has done her elk hunting with a .308 Win and 130g TTSX @ 3045fps. I figure that would have worked out
to about 500 yards at 7000 feet and above,.
130 ttsx /500yd (7000ft) would give about 1250 fpe , if claimed BC .350 is correct.
with a possible B.C. error of up to 5% , it could be more like 1195 fpe / 500 yd.
That is significantly below 1500 fpe, so Im left wondering what the actual real world minimum energy level is that you would
be prepared to shoot elk with?
