Midsouth "Dogtown" bullets--too many rpm?

[rockrat]

I bought a Savage 12 Bvss-s in .223 and have been trying out a few loads. Been trying the 55gr Vmax bullets, no great success yet, but decided to try out some of the "Dogtown" bullets I have shot in my Rem XR100.

The Savage has a 1-9" twist and IIRC the Rem a 1-12". I have also shot the dogtowns in a XR100, but in 22-250 Vs the other one in .223 and they work very well also. IIRC, the 22-250 has a 1-14" twist

Problem is, in the Savage, I shot 5 shots @100 and three went into about an inch and the other two went in sideways!!. One next to the the three normal holes and the other about 3" away.

Wondering if the faster twist rate on the Savage is causing a deformation of the dogtown bullets, because of maybe exceeding a rpm limit, which is causing the bullets to strike sideways?

New to this quest of trying to put bullets in tiny little groups.

Also, any recommendations for a decent bullet for this rifle?

Thanks

I am going to say it's probably a 14" with a defect, I could be wrong. Are you familar with the cleaning rod technique to measure the twist rate? Adam

The 1x9 twist is fine in andy 55gr situations, the 1x12 is fine in them too, so i think you have an instability/rpm problem,

try reducing the load on dog town and see if the slower velocity allows stability in the rifles. if not then i would say bullets are worth what you pay for them.

Compare them with the equivalent weight varmint bullets made by Sierra & Berger. Shoot them side-by-side, identical loads, bench equipment, wind conditions, etc. If the Dogtowns continue with problems, then I would have to say what Bob said, "bullets are worth what you pay for them".

The faster twist barrels ( in your example, 1-9) spin the bullet at a higher rpm, and internal defects will showup sooner than in a slower twist, like your 12 & 14's.

I personnally have little or no faith in these bargain priced bulk pack bullets.

 

[rockrat]

Mainly got them to shoot in my "black rifle", but thought I would try them in the Savage and the Rem. Think I will just relegate them back to the AR15.

Yes, I am familiar with the way to check twist with the cleaning rod.

No, the bullet is coming apart out the end of the muzzle....

We had the SAME problem with a 500 count box of Z Max bullets (from Hornady... hahahaha). When we went to the 600 yard line I could see them exploding at about 50 feet from the muzzle and they never reached the target.

We have had ZERO issues in the same Savage 1-9 223 with the SOFT POINT Dogtown. You might have the hollow point Dogtown, I don't know.

Please don't buy them, they suck. They are only made by Nosler.... Saves more for me.

No actually they are awesome. I see no difference between these and you typical V-Max or Nosler.

I shoot the dogtowns in a custom 223 AI 1-10 twist and in both of my black rifles and also in a old 722 in 222 rem. with no problems they don't shoot quite as good as nosler ballistic tips or hornady v-max but for the price they kill just as many pd as the rest of them.

I have shot many thousands of midwayusa dogtowns in all my 1/9 twist .223s with never a keyholed round at 3300-3400 fps. They do a nasty job on p-dogs.

rockrat.........I don't know what the RPM limits are for your bullets,but I do know Speer 52gn fbhp will "over rev" in a 1/7 twist AR-15,however Sierra's didn't blowup.
You can compute your RPM's if you know your MV.
RPMs=(12/twist in inches) X 60 X MV. Example....12/9=1.333 x 60 x 3,500=279,900rpms

They are the soft point "dogtowns" Working with the 55gr Zmax right now, but going to try some 60gr Vmax soon.

Hmmm... we shoot those no problem. Call Midway and tell them.

I saw a similar problem with the speer bullets mentioned by gpoldblue . They shot very good in my 1x9 McGowan barrel but when my buddy shot them in his 1x9 Savage, they all exploded at about 30 yds. Both rifles were 223's. I just told him that his rough Savage barrel was causing the problem. That got the conversaton going!

Blew up a bunch of them in my 12 twist 22-250. And have seen some go thru sideways as well. My .223 is only a 14 twist and seems to shoot them ok.

One 22-250 was dusting Vmaxs and ended up being being because it would copper foul real bad,cleaned it for a few hours to get rid of the copper and they were fine for a while.

Not a 223 but a 204R testing 34gn dogtowns. Got them up to 4350fps with no problems.

What twist rate do you have in your barrel?

 

[jo191145]

A 12 twist.
I know its an apples to oranges thing.
Just trying to dissuade the notion that while Nosler does suggest a velocity limit to the DT's its not always necessarily valid.
