Frangible

[cory]

I'm looking for a good Frangible Bullet for a home defense load now that I've got my Grendel SBR built.

Vmax seems to be out of stock everywhere, but I can find the Sierra 100gr HP Varminter.

Does anyone have any experience with this bullet or any others I should be looking at?

The Sierra 85 Varminter is one nice pill. Being a bit lighter, it won't over penetrate quite as much as the 100+ grain pills, and it is EXPLOSIVE! It also is the most accurate round my 18" BHW shoots and, like the name implies, is one helluva Varmint round. (PDogs never had a chance.) A bit expensive, but an excellent substitute for the VMax.

Considered these? http://www.lehighdefense.com/collect...ant=1073851692 The wound cavity video is impressive.

I like the 100g Sierra vmter but the jackets seem to be pretty tough, if I were gonna choose a bullet for home defense it would be the 90g TNT. Very explosive on gallon jugs of water. I Haven't been able to recover any jacket or lead from the jugs I shoot, I'm gonna have to try them from this 12" barrel I just got today!

I still need to try the 85g Svmt, but I'm sure the the jackets are just as tough as the 100s.

That bullet looks pretty darn good, but I'm thinking when Cory said frangible he wanted something that won't pass a sizeable slug out the bad guys backside. If overpenetration isn't a concern, then those look pretty mean.

Yeah, I'd probably try the 90gr. TNTs and the 85gr. Sierra HPs. I tinkered with the 85s a little but never accomplished much due to time constraints (stupid job!). I never checked how much makes it out the backside of an H2O filled milk jug though.

With cans in the mix I stay away from true frangible ammo as much as possible. I have some different kinds (in other calibers) from work, and I keep it highly segregated for fear of crashing a baffle stack because I wasn't paying enough attention to what I was shooting at the moment. If there is a way to screw something up, I have to be extra careful because I have a knack for finding it.LOL

Reading up on the lehigh stuff, I caught something I was unaware that lead to a google search. So we're not suppose to shoot frangible bullets through a suppressor? It seems to make since if you're shootng cheap unreliable bullets, or shooting a light pill at excessive speeds, or a combination of the two. However, short of a flawed in the manufacturing of the bullet I don't see why this would be an issue with a Grendel especially an 11.5" barrel.

In any case I should add that I intend to use a can. This does make the Lehighs more attractive. The relatively slow moving slug may be an acceptable compromise. I'd really like to see what it does when it hits sheet rock and 2xs.

Has anyone experience the "puff of smoke" out the end of their barrel shooting the sierra stuff or the Vmax? Has anyone experienced keyholes with any of this stuff?

The first concern for me is over penetration inside of my house. I'm confident in my ability to hit my target at this range. However, I'd still like something that's going to break up at the first object it hits if I do have a miss. I don't want to hit a neighbor or, worse, a loved one within the house.

Yeah, "true" frangible bullets (compressed powder/sintered type bullets are verbotten in suppressors. That's why I worked that in there. I didn't want to assume too much, but I toss out the warning every chance I get.

As long as the projectile is jacketed or some type of machined solid you should be good to go though.

The Lehigh bullet will peel off it's front section (doing groovy damage in gel and dirtbags), but you'll be left with a sizeable solid copper "wadcutter" exiting the rear of the target. I imagine it'll go a fair ways through sheetrock.

As for blowing up jacketed bullets--- Barring a serious bore defect, damaged/partially obstructed muzzle device, or suppressor baffle strike, I doubt that'd be likely at all with short barreled Grendel velocities.

A guy brought me a Beowulf that was peeling jackets and leaving weird slices in the targets at close range once. It turned out that he had someone put a muzzle brake on it that hadn't been reamed out enough (aftermarket gill brake originally intended for .45 bore stuff). I laughed (since no one got hurt) once I figured out the problem. Thankfully he hadn't shot it with someone standing adjacent the brake, because it slicing the Beowulf jackets right down the side on the way out. Ouch.




ETA: Lehigh bullet----- In a gel test of the 145gr. .308 version, the base penetrates 26 inches...

I have shot a yoter with 100gr sierra at about 60 yds and was not pretty, exit hole was about the size of a soft ball, DRT!! good for me bad for the yoter!!
If your worried about over penetration why not use a shot gun?? there is no mistaking that sound when a pump action cycles......... #4 buck close range, just have to be in the general area to put a hit on target. Have you looked into the Keltec pump shotgun 14 rounds 2-7 round tubes. It is very short easy to handle, can have a sling added so it is harder to take away from your person. I understand that you want to use the your rifle, maybe a subsonic load is what you should look into as well?

Thanks for the heads up!

I'd think the 110gr chaos from a blackout would be closer to what we'd see from a a 95gr chaos in a Grendel.

This has more worried about using the controlled chaos.

I'm thinking the controlled chaos in a 130gr - 140gr pill from the Grendel might do the trick.

Thanks, but my first concern is removing the threat. I'll never trust a shotgun for that and the over penetration of a buckshot is the same if not worse once it spreads.

I'm not rying to take a shot at you man, but I don't like the "scare them off with the sound of a pump action cycling" doctrine. If a threat to my familie's life or my life is inside of my house, I don't want them to hear me until I pull the trigger or see me until I pull the trigger if possible.

The Vmax looks like a good option still.

I had some problems with these. They kept jamming into my lands until the jamming forced the bullet significantly deeper in the case allowing them to feed properly. What length are y'all loading these at?

At the distances involved inside of a normal house with a shotgun you would have less of an over penetration issue using #6 or 7 1/2 size shot. It would still be very lethal also. I agree with Cory, if a threat is in my house there will be know warnings unless I have been able to get a dog. Then if the dog is chewing on them I will get closer so I don't accidently shoot my dog!

Anyone done any testing of these varmint bullets on drywall to see how far they go?
