do you know your rifles trajectory?

Yes - Note that piece of masking tape on the front of scope.

Yes

100 = 0
200 = -3
300 = -13

That's all I need to know.

Sorry I was a little harsh.
I just know that at that range, a 50 yard mistake is a 10" mistake.
My hunting group shot 3 this year with there front leg blew off and 5 others that were gut shot.
Sorry I took it out in you.

I have made efforts to do the same thing with my reloading ever since I bought my second rifle in 1979.

A lot of hunters are very surprised that dissimilar cartridges will shoot very similar trajectories with a bit of thought as to bullet choice and powder charge.

This is a representation of my rifle cartridge selection and loads available.

................................................................................100 yd .. 200 yd .. 300 yd .. 400 yd .. 500 yd
22-243 AI .... Hornady 60 gr sp .. BC .265 ... MV 3650 ....... 2.6 ...... 3.5 ........ 0 ...... -5.1 ...... -16.3
6mm-284 ....... Nosler 95 gr BT .. BC .379 ... MV 3300 ....... 3.0 ...... 3.8 ........ 0 ...... -9.1 ...... -24.8
260 Rem ...... Nosler 120 gr BT .. BC .458 ... MV 3100 ....... 3.4 ...... 4.1 ........ 0 ...... -9.6 ...... -26
264 Win ....... Nosler 130 gr AB .. BC .488 ... MV 3200 ....... 3.1 ...... 3.8 ........ 0 ...... -8.8 ...... -23.4
7MM STW ... Hornady 162 gr btsp BC .514 ... MV 3200 ....... 3.0 ...... 3.7 ........ 0 ...... -8.7 ...... -23

And a couple I set up for buddies and a couple I no longer own.
25-06 Rem . Hornady 117 gr btsp BC .391 ... MV 3050 ....... 3.9 ...... 4.7 ........ 0 ..... -11.2 ...... -30.2
270 Win ....... Nosler 130 gr BT .. BC .433 ... MV 3100 ....... 3.4 ...... 4.2 ........ 0 ...... -9.9 ....... -26.7

340 Wea ..... Nosler 200 gr BT .. BC .414 .... MV 3140 ....... 3.4 ...... 4.1 ........ 0 ..... -9.9 ......... -28

The 260 Rem load is the only load pushing against maximum. It was worked up with moly plated bullets.

The next barrel on my Savage 22-243 AI will be fast twist so it can handle a heavier bullet. Then that trajectory can be tuned right in with the rest of my hunting rifles.

I maximize the effectiveness of every chambering/boolit I shoot and could give a schit less,how it compares to something else I have in the herd. No schit a +4" 100yd "zero"?!?

I've zero interest in schit boolits,at schit speeds,with a schit zero,so as to make everything schitty. Always fascinating to watch folks pull spark plugs and then honk the horn.(grin)

So...ummm...yes,I've some familiarity with more than a few zero's on more than a few rifles and their downrange behavior(s).

Understatement +P+.

What's the 100 yd trajectory on that 7-08 sans turrets?

I can't much like anything higher than 2.5" at 100yds.

A 162'Max at 2700fps launch,will zero at 225yds when 2.5" high at 100yds,with 1.5" sight height in standard atmosphere at 2500' ele. 1000yds is a sub 28MOA correction,full value 10mph wind is sub 6.5MOA,remaining velocity is 1500fps+ and "energy" is 825ft lbs.

For conversation,the STW load you cite zero'd at 250yds,gets to 1K with 20.7MOA,6.2MOA full value 10mph wind,1658fps and 988ft lbs. In the above atmosphere/sight height.

More conversation. I shoot my 7WSM's with the 'Max at 3150fps and a 250 zero. 1K drop is 19.1MOA,wind 4.9MOA full value 10mph,1850fps and 1232ft lbs of "energy". Same atmosphere/sight height.

Gonna try turrets some day,as it seems like some guys like 'em.

I, and the crew I grew up shooting with never could get away from that 300 yd zero. We hunt the same terrain year after year, and 90% of our shots are 250 to 400 yds.

Tried a few turreted scopes, but my budget did not allow me to go where they could be reliable.

If a guy is slumming Bushnell and Burris, he's best off to forgo the gadgets.

With a bit of practice a fellow can learn to kill even little bitty ground squirrels at various ranges via appropriate hold under.

That WSM load is pretty impressive. The 160 Amax is slippery, and I think I heard somewhere that it kills stuff pretty well also.

If I was not so inexplicably fond of this #1, I could sell it and get a 700 in 7WSM. But the STW has not failed me yet.

I zero'd all my 257Wby's at 300yds,but again...the midrange was slight,due to modest 100yd height.

Shot alotta 120's crowding 3800fps in my STW's,back in The Day,which was pre-LRF. Have had multiple No 1's,but never in STW,mine were bolt guns. My B-78 7mmRemmie was Skookum. All of which,was of course prior to the advent of S/S OEM offerings.

I've more than a whole buncha faith in a 7-08,wayyyyyy past distances thus far cited.(grin)

I have no swag-er

Wind is spelled "SWAG".

Yesterday was a literal breeze,with 1/3 Mil full value influx at the 750yd line,via 75 HPBT's from a 2800fps initial Krunchenticker Launch.



Funny how it works.

I'm still laughing at that one.......
