What 7mm bullet do you recommend for 1 mile?

[SKWERLZ]

The 190 Berger has fast become one of my favorite bullets. Very easy to tune.

And for me it had a more consistent BC than the 190 Hornandy.

I was gonna try my 195 elites in my 28 nosler for the mile. (They were one of the easiest bullets to get to shoot good in my gun and i tried 180 hybrids and the 180 vld) But didnt get out earlier this year when it was clear of vegetation and cooler. I shot a few to 1400 to check bc and drop calcs. Might have to look at the 190 lrht. Sounds like its a good one too. I liked the 208 lrht in my 300 wsm for the mile.

Thank you to everyone who has contributed!

How do you determine BC at a mile. I would not know where to begin.

 

[Rob01]

The 180 ELDs did great for me in my 7mmRM. Hit a 12” target 2 out of 3 times at a mile and the miss was a hair off at 3 o’clock as I was already hold a little over 4 mils of wind.

I wasn’t determining BC, I just observed vertical deviation compared to measured velocity over time.

In the data I've seen from 1 mile.... the 190 ATIPs have the advantage. Unless you get into custom bullets like Warners. If you go custom... you need to tell the bullet maker to the .xxxx" place the bore and groove size your barrel is made to. Otherwise I don't feel you get all your suppose to out of the solids. Watch your twist also.

Around a 1k yards and less... none and I mean none of the bullets that were used for pressure and velocity testing from the accuracy data I got back for the 7/6.5PRC. That no bullet just ran away from the other ones. Then it comes down to your load and what your gun likes and the guy pulling the trigger and reading the wind.

Yes you need a 1-8 for the Atips. If you try the 197SMK you need a 7.5 twist if I recall correctly.

Go 5R for rifling. It is proven now that it helps the bc and the flight of the bullet vs conventional rifling.

Thanks so much for your time and response here Frank
Good to know 5R is beneficial for the BC
If I may ask, is it worth it to go with a Gain Twist for such a caliber
and what would you suggest to arrive at an 8 twist
For instance an 8.3 to 8.0???

Need to know your velocity (Have a Chrono)
Need to know your Scope Elevation adjusted up for a Mile, from a 100 yd zero
------------------------------------------------------
Then plug in all other parameters in an App and adjust BC until it coincides with your adjusted elevation.
Your Scope height above bore centerline is critical to have an accurate DOPE throughout your elevation adjustments and yardage ranges.

I should add my experience with the advertised bc of the 190LRHT is legit and needed very little adjustment in DSF on my kestrel to get to two miles.

Did I read that correctly 2 miles?!

Yep

Yep

2 Miles!!! I LOVE IT! (and I believe you, I can tell you're that kind of guy )
What power magnification on scope and brand of scope can you see bullet splash that far?
I'm out to 2200 yds (1.25 Miles) and thats about my limit for visible splash with a Kahles 6-24x
It does really well though even on 18x at that distance
-------------
I'm trying to base a higher power scope selection on that exact criteria
being able to see bullet splash to about 4000 yds

 

[Rob01]

I think that would have more to do with the bullet than the scope. Like spotting a .223 at 1000+. Also what you are shooting into. I had no problems seeing splash with a 408 at 2500 yards at 17x because it’s a big bullet and the ground was drier so it showed a good impact.

408 Chey Tac or 416 Barrett would be ideal for this stuff.
I've shot a 416 and loved it, could not believe the muzzle brake was so effective I could shoot and shoot and not flinch or worry about shoulder fatigue.
(Tip - don't shoot your AR 500 Plates at 600 with one lol)
------------
But more wondering visibility of bullet splash with 7mm
180 gr and above

 

[Rob01]

Yeah we were shooting up in Idaho with the CheyTac guys and they had targets out to 3000 but it got knocked down in a storm. Those rifles really are soft shooting with what they are. It was a blast literally and figuratively. And no we started at 1000 and went out. lol

Yep
Spotting was the hardest part.

Hung a piece of steel on a giant rock face, once we saw the impacts and saw what the winds were doing to the bullets it started being fun.

29X but I’m rarely higher than 25x
Athlon scope.
Here’s a fun one, 20” 338 Norma at 2500 yards with a 4x16.

I have a Garmin chrono.

Guess I need to get something to do the calculations. What is a good app?

Anything else I should get?

Lapua's Ballistics App for Iphone,
Its all I use now,
I use to use Shooters Calculator . com online to print my Dope charts
(Still good for a hard copy in case the phone dies)
but the Lapua app has everything you need and works even if you don't get cell service.
-----------------
get a Rangefinder that can range as far or farther than you intend to shoot
I don't know how any times I go to shoot across the canyon from Mtn to Mtn....
and my rangefinder is tapped out showing ---
Which then you have to be good at using your Mil Reticle to know how to range to bracket them in
