Ballistic chart for Wolf 100 gr steel ammo?

[ahillock]

Has anyone come across a ballistic chart for the Wolf 100 gr ammo?

[VASCAR2]

I read the BC is .40-.41 for the 100 grain FMJ Branual bullet, seems pretty close from the test I've read.

Yes that is also what I have seen for BC of the Wolf round.

I was hoping for a ballistic chart that had the velocity, drop and drift out to maybe 500-600 yards. I don't have a ballistic calculation program that would out put the data. Was curious if someone already had a chart to share.

plenty of ballistic caclulators online

I used Strelok on my iDevice. However, just tested it this weekend and am considerably off in reality out to 400Y. I think my velocity must be wrong. I learned the hard way that you need accurate information (velocity out of YOUR gun, BC, etc). My first attempt was pretty off (calculator said .7 MIL at 200Y and I was at .3 MIL, 1.6 at 300Y, i was at 1.0MIL). Someone wisely said "make a chart then go prove it right/wrong." Mine was mostly wrong

For what it's worth seems like most people are guesstimating .390 or .400 G1 BC for the bullet. Plug that in with the expected muzzle velocity out of your barrel into a ballistics calculator to get a rough chart of what to expect, then go verify it as much as you can.

David Fortier has gotten the following velocities out of these barrels with 100g Wolf:
12.5"..............2431
16".................2496
20".................2600

You can use that as a guide if you don't have access to a chronograph.

I've been looking for info on the steel case stuff. I was specifically looking for any kind of gel testing. My Google-Fu has been weak... Can anybody point me to gel tests of the Wolf? Simply a matter of curiosity. I know the steel case stuff wasn't designed for terminal performance. But does it tumble or does it ice pick?

I've seen the claim that it was "designed after the 7N6" but color me skeptical... Still, it would be interesting to see.

I am disappointed by the low velocity. How can a 100gr bullet only get the same velocity as 123gr bullets? I would expect 2700 from a 20" barrel.

I wanna say Dave Fortier has been the one reporting on the effects of the Wolf 100 grain bullets and most if not all the info we know about it's terminal ballistics have been from him and what he's seen from it, though it does appear there's at least few hog hunters that have pretty happy with it's performance.

In regards to the low velocity, from my experiences that just how any kind of Wolf steel cased ammo is loaded. A good comparison would be the new Federal 100 grain TNT load. From my 18" barrel I average 2894 fps, however each load serves a different purpose and are priced accordingly.

I was really surprised to see that velocity from a factory 100gr load but when I looked it up, turns out to be a 90gr load.

Since I'm doing the first Grendel upper as a dedicated long range rig the steel case doesn't fill a need for me right now.

I could also do a 16" or shorter upper for short-medium use. But then I have rifles that fill that role now in both 5.56 and 7.62x39 so does it bring enough extra capability inside 300 yards to justify...?

[maxxmojo]

Man not sure why I was thinking it was 100gr instead of 90gr. For being only 10 grains lighter though I'd say it's still cooking pretty good comparatively.

Ballistically speaking, it's going to be much closer to 7.62x39 than 5.56. The upside to having a rig in 6.5 to replace those to would be commonality of parts, especially mags, and ammo (in case you need to use LR ammo in a pinch or vice versa). The downside is you'd have to obviously build or buy another gun. Really just depends on how you want to go about it.

Seems like you're inputting too low an MV. Your results suggest an MV of 2850fps if we use a G1 BC of .400 and an AR-height scope mount. That's cooking...

sorry missed this a while back. I was using some of the values given by others, closer to 2600/2650 (I have an 18" barrel). I don't know that anyone has any actuals of 18" or maybe I've missed them (Wolf 100G)

Thanks!

Edit:
Values listed above were apparently measured. Not sure that I would be getting 200+ higher!

I think the Wolf is slower than it should be, so I would err on the side of slower numbers, unless you've got actual chrono results?

[VASCAR2]

Here are the chronograph results from an 18" 6.5 Grendel II barrel from Brownell's. The chronograph was a Magnetospeed and the temperature was approximately 70's when we chronographed these last year.
