So the Tikkas are made in Riihimäki? How does one even pronounce that?

Ree
Him
Ahkey

And the Ahkey sounds like teriyaki.

Just say Finland.

8

 

[Castle Rock]

Yeah, fumble fingers

You taking about the 53gr vmax with the .29 G1 BC?

Beautiful. Did you use a uni-throater? I’m going to try the same, except for the 88 ELDs on a 7 twist barrel.

 

[Schmo]

Yes, rented a unit-throater from 4D.

 

[Pharmseller]

8

And no issues with stability. That’s impressive.

I’m getting 2915 with the 75 ELDM, 24” barreled Varmint.

Have yet to shoot the 80s yet, so we’ll see. I know what velocity bracket I’ll be in though from other loads I’ve run. Should be 2900 - 3000. The 80 ELD-M box says 7 twist, but the website says 8 twist. Anyone know what stability number is safe? Is it anything over 1?

Do you know about the spring question? Do the ascension mags need a spring from specifcally a 4rd 223 mag or do springs out of the various 3rd mags work?

I used the spring out of the mag that came with my compact 223. Couldn’t tell you if it was 3 or 4 rounds tho. Either should work

I got this from another forum years ago.



80 gr in a 1-8” is on the edge, might not be suitable for long range. Stability decreases with velocity loss.

Berger stabilizer program says marginally stable at 3000 fps at 2000’ elevation.

1.160”, .244 G7, SG 1.23

My load is also “marginally stable” at 1.33 but it shoots very well out to 500 yards.

Depends. Bare muzzle, just try it and see. Using a can, technically 1 or more, but I personally would want some wiggle room for changes in atmosphere and lower velocity rounds.

 

[Schmo]

77TMKs shoot very well out of it at least

Hornady 4DOF lists my muzzle stability at 1.22 for my elevation. I’m at 1,230’ above sea level. Highly unlikely that I’ll shoot or hunt at anything lower than 900’. Most is done either at my elevation, or 3,000’ - 6,000’.

Stability decreases with velocity loss.

4DOF shows the opposite. Because rotation does not decrease near as rapidly as velocity. See attached picture where it shows gyroscopic stability increases with range.
