Best target medium to simulate effect on prairie dogs (video update)

[Mike402]

Live targets are the best!! LOL
220 Swift shooting a 55 Sierra about 3850.

Just curious, what's the twist rate on that barrel?

I believe that it’s a 12 twist

Ok sorry I enjoy geeking out on this stuff.

So with a 12 twist at 3850, you are looking at 231,000 rpm. Not sure which bullet you are using, but according to Sierra, the limit on the varminter line is 216,000. On the Blitzking, its 352,000.

So if you are shooting the varminter bullets, you should be good with that twist, even though its slightly over the limit. If you are shooting the Blitzking, you could potentially move up to an 8 twist when its time to rebarrel and get 346,000 rpm, which would be orders of magnitude more explosive. WAAY more destructive than the VMAXs in my video. Would love to see that on video.

This is twisted, but a stretch Armstrong doll will perfectly correlate to prairie dog damage.

Not sure about that. Wouldn't have the blood splatter effect, unless you start injecting jello in there lol

Also another thing I've learned from doing this is that I'm not shooting anything that I can't buy at the Dollar Store

25-06 w/ 75s sounds devastating. Would love to see that. I have a Youtube account and posted it there. If you don't have any way of posting it, I'll post it on my account and put it on here. I'll pm you my email address so you can send it to me if you like.

That combo on crows on snow is something else! A 223 with 52 gr. Nosler Varmageddons isn't anywhere close to the devastation the 25-06/75 Vmax combo.

What kind of realistic velocity would you get with the 25-06? Just curious how that would stack up against a 6 Creedmoor w/ 75s

Edit: Nevermind. I just checked my copy of the hornady 11th edition reloading Guide. Course we know you can hot rod it as it’s conservative but just as a comparison appears 25/06 has a 100fps advantage w/ maximum loads vs a 6 Creedmoor w/ 75 VMAXs. The upside is that the 6mm has a G1 BC of .330 whereas the .257 version is .290.

Now if you want the ultimate quarter-bore load my Lyman #50 Edition shows a 75gr Sierra HP #1600 being
sped along @4081fps in a Weatherby Mark V, 257WBY using 71gr of IMR-4350 sparked by Fed 215 primer.

I'm running them @ 3560.

I had a 12 twist 6-284 that shot 75 v max pretty well, and they clipped along at about 3,750-3,800 fps out of a 28” barrel. I’ve shot a “few” prairie dogs in my life, and nothing I own created the carnage on a prairie dog that this chambering did, followed very closely by the 25-06 w 75 v-max. I’ve found 1” diameter pieces of prairie dog some 20 paces behind impact.
Colony varmint volume shooters they are not!

Now that would be great to capture on video...

Whoa... that's insane. I say that because I have seen the destruction they cause at 3500fps

 

[Tommie]

Wait a minute. Is this video proving that target bullets don’t dump their energy into small varmints? Say it aint so!

Nope the point was to compare different types of targets to see which emulated the effect of hitting prairie dogs. People in here threw out some pretty creative ideas. From there compare different bullets/loads to see which are more destructive. Started out wanting to see comparison between target & varmint bullets as a baseline. Next one will show all VMAX bullets out of 204, 223, 6BR, & 6 Creedmoor

I almost feel like one has to show these in slo-mo to appreciate what's happening

 

[Mike402]

I took the liberty of editing your first video and slowing it down to add a little drama. Hope you don't mind...

Hydraulics, key word for the subject. Mid day when they are laying flat on a mound looking at you, hold on the chest or bottom jaw for best “lift”

or just under the tail when they are facing away from you!

I do prefer the shots where I can watch them spring straight up along with recoil, usually find hitting them low will do the trick nicely, doen't matter what the bullet is, as far as I can tell, does it with 22LR up to 22-250 when you hit them right. If I could figure what it takes to get them to spring up and explode at a foot or two in the air, in like the occasional one does, that would be nirvana.
