Ever load a bullet that should not of worked on recommended twist rate?

[370bc]

I was just wondering, if say a person had a 1-12 twist rate in a 243 win, where the barrel and bullet manufacturers say up to an 87 grain bullet weight will stabilize, Only to find out that the heavy 105's did stabilize?
I loaded up a few 105 bergers to do just such a test. I can be hard headed at times.
Just seeing if anyone else has had success where success should not of been the result in regards to twist, bullet weight, and bullet design.

Absolutely. I loaded a 75 gr Amax for my22-250 w a 14T and it was perfectly sideways at 25 yards. Hard to believe at that velocity.
I have also tried numerous other 223 projectiles at various weights with 12T, 9T etc where they have stabilized and probably shouldn't have. Giving it a try won't hurt anything other than accuracy

Someone published a twist rate formula that is used in some of the available calculators. Don Miller maybe? JBM? Bryan Litz?

I've found this formula works pretty well in cases where the manufacturer's required twist rate seems overly conservative. I think the manufacturers specify a rate for the worst possible conditions, but the calculators let you enter your real conditions (altitude, velocity, etc.)

I've done it and in my case the charts and the experts were right - it didn't work. :

Friend of mine's pushing 308 155 Hybrids thru 1:15's at speeds I'd be real careful approaching were I to attempt it. He wins long-range matches doing it so there must be some truth to what Brian Litz says about bumping velocity up if a slower-than-optimum twist is used... at least until they blow up that is.

OP...are you telling us that you got 105's to work in a 1/12 bbl,,,Roger...

I miss read this story printed in outdoor life about barrel twists.

I thought it said a 1-12 would stabilize a 105 or a 107. I read too quickly.
I loaded up some 105's and they grouped about 5" @ 100 yards.
Guess I was hoping for a holy grail that woul allow a 1-12 to stabilize the 105's
The law is confirmed for me. You need a 1-8 to make the 105's group acceptably.

95 VLD's out of a 1in14 hit the target perfectly sideways @ 32 yards (my patio table to the woodpile )

What I have ran into is a twist rate (1 in 10) that's supposed to work for 25-06 and 257 Roberts that don't seem to work (at least as good as it should) with 120 grain bullets. I just can't get any consistency out of them , and believe me I have tried. My present rifle is a 257AI Ruger 77. Barlow

Some folks like redheads, some blondes, some brunettes!

Some rifles like various bullets....that aren't supposed to shoot good!

When I here of stuff like this I always wonder if a faster twist barrel slipped into the slow twist pile before it got stamped with the twist rate. But I have tried 50 gr berger 204s in a 12twist. Sideways 5 shots in a row. Here's a funny one though. Friend of mine was trying 208 amax's in a 10 twist 300 win mag for the first time. We were shooting 665 yards. After 7-8 shots we went down there to find about 5 keyholes. Baffled, we went back and fired more, and then i noticed the vapor trail leading into the ground short of the target. He forgot to adjust from his zero around 500 yards. The bullets somehow deflected off the ground onto the paper making a perfect keyhole. That gave us a good chuckle.

That's wild! And dangerous!
