Who has a barrel faster than 8?

trying a new solid? otherwise you might be able to make dust out of most jacketed bullets

I want to shoot light jacketed bullets and see what rpm they come apart at, if any.

I'm shooting a 7-twist Douglas on my Remmy bolt gun. Also had a Douglas 7-twist on a Howa bolt gun. Works well.

I am saying 1:10 is the new 1:12 and 1:8 is the new 1:10.

I got the 1:4 twist today.

The point of my question was to find out how common faster than 8 twist guns were. Outlaw sent me some 250s to try in my 16 and 10.5 guns to see if they would stabilize. 60% did @ 100 yards in the 16" gun. All of them were tail dragging in the 10.5" gun. Oddly enough I was getting 1.25" groups with them. They're going to need 1 in 7 or 1 in 6.5 to fully stabilize. At this point I don't believe they're going to produce them, but there may be a possibility of small batches for guys with faster twist barrels.

Interesting that you seemed to find a correlation between barrel length and stability too. People say it's twist rate vs. velocity, but there is more to it. Unless of course your 10.5 has a slightly slower twist, say 8.25. My best subsonic group so far with my 10" barrel has been 5 220 Prohunters into an inch. Funny thing is, they were 'taildragging' too.

My 10.5 shoots 240s into a clean hole. The 250 Outlaws are shorter than the 240 SMKs, but do not fully stabilize @ 100yds. At 30 yards I get perfect round holes. I've seen this before in a 308 and a heavy bullet. They were stable and round @ 100 yards and shooting good groups, but at 150 groups opened up and the bullets were unstable. I've come to the conclusion that the OAL of a bullet, altitude and RPM in subs are not the only factor that determines is stability. It seems that a bullets weight distribution is also a major factor. I have no explaination for the barrel length issue. I have seen this in more than one gun. Both are running as close to 1050 as possible in a 1 in 8 so theoretically both bullet should react the same. As always when dealing with subs "Think backwards"
