When you say that you are going to pick on me, my assumption is that you made this statement in jest, it is my nature & purpose to feel this way,
but only you know that. Also, I understand some of these questions being asked, especially the velocities, as they are high, though doable.
I will take it point by point.
(1) Concerning the kills, about half were bang-flops, when you say you expect some to run, so do I. With 300 mags or anything else, I do not get 100% bang flops out to 400 yards. In the past, we would get 70-80% with the 117 Sierra, but we quit using it to get a slightly harder bullet, trading a few more dramatic kills for more penetration. I don't think some of the Deer moving is an issue, as the blood would be there anyway for 100% recovery even in the AR. thickets, not a factor on the Wyoming plains. :?
(2)Are these speeds chronographed? Yes, they are as they are for any
Varmit, Target or Big Game rifle that I own. How else can I know how
to do my drop & wind chart to tape on my stock & know exactly how to use my Mil-Dots? I prepare on paper & on targets @ a much greater distance than I will shoot at a Game Animal & then the hold over on mils
@ game ranges is second nature.
(3) Concerning the velocity, again I assume that you are not picking on me, so I have to assume that you only had this one reload manual or
you were in a hurry. Otherwise, if you were picking on me, then you
are trying to show the Wea. #'s low so that my AI #'s look unreachable.
The Nosler # 3 shows 3,260 & we may say big deal, but the Nosler Data
is with a 24" barrel, I am using a 26" barrel. Anyone would agree that
2 inches of barrel in a overbore round like the 257 Wea. would lose
100 FPS, but for fun, let's say 60FPS though laughable, add this to the 60
FPS stated difference & round it down to 100FPS to be very conservative, same round, 2 different manuals, which is common, & get this, Hodgdon
# 27 shows 3,325 with IMR7828 & the 120 Nos., sorry you missed that.
I have the New Sierra Manual #5, WHY DID YOU NOT MENTION THE 25-06AI DATA THERE? They show 3,200 FPS with the 120 & that is with a 25-06 OAL & mine is THROATED for longer bullets so that I can use more POWDER. Hey, it's starting to look easier.
I always advise reloaders to back off at least 10% from max. in manuals
& work up & I always will but my loads sometimes & in this case are a little over max. , a hair it appears but SAFE in my rifle. The Manuals are lawyerized & that's fine & that is why I NEVER give powder charges.
Your velocity of 3,079 looks reasonable to me. I Did not see if it is a 24" or
26" & it sure matters in this round! Let's do some 1st grade math, well
12th grade now. Your Load:......... 3,075
AI conversion: 125 FPS, no let's be very conservative:......... 100
MY barrel is a very slick barrel, fast barrel, 80FPS faster than
my brothers barrel, let's make it 40 FPS, but yours may be fast 40
Difference in Powder could easily change vel. by 50fps 50
3,265 hmmm
If you have a 24" instead of a 26" 100FPS, no let's make it 50
3,315hmmm
If your barrel is fast too & 26", 3,225 of course with 7 whooping gr. diff.
in bullet, but this exercise is only to show variables that exist, difference
in Manuals, etc.
It does not matter, as the Sierra manual proves the point combined with
my longer throat.
(4) What is my case life? About 6 firings, not counting fire forming. In hot
weather, which is when I check the loads for pressure, more like 5 firings.
No, my chrono. vel. given was not done in hot weather. I have easy bolt lift, no shiney ext. marks, no danger signs. I load these for performance,
not long case life, 250 rounds of brass will last awhile & I use the 223, 308
& 22-250 for volume shooting/case life.
I have noticed that a couple of the moderators & several members live
close by, so if this velocity seems just too much, I bet I can arrange
someone to verify it, again if you are picking on me, a friendly wager
perhaps & we can post the results, but if you are only asking, that is cool
with me.
(5) I did not give the ranges of last year because in that hunt the rifles
were in 25-06AI & the original question was about the 25-06. You will
find that I am painfully precise, but if it is important, from 70 yards to
406 yards.
(6)What kind of rangefinder? Bushnell, 800 yard, later generation. Even
though they were newer ones, some days you don't get good reading & are more sensitive than the Swarvo. or Leica. The way that we verified this was if 2-3 of us got the same exact readings, they had the right
conditions in light & so-forth for that day. Combining this with Mil-dot
Scopes & a guide that was the best at the range game that I have seen,
if all 3 ways dovetailed, then we were good to go. Then after the shot
we would step off the long ones & things went fine. Some of these times,
this data did not come together & wo would hold our fire, that simple.
Sir
I may sound a little too frank, but the way the questions were asked lead me to question the reason, if it was for information, I believe that is what
the Forums are about, but if not I have a right to know & I will allways be
prepared to verify what I post whenever needed. If the term "picking
on me" was in jest, then my brash comments are als in jest.
These 400-425 yard shots were viewed by us to be the exception & not the rule, about 20% of the shots. They were not taken unless all factors were known & the animal allowed a good shot. Under all these factors
the 25-06 will deliver on Deer, the original question & Yes, Elk are killed with it, But not me, I will use my 300 & such for that job or for shots over 400 yards.
