Good day gentleman!
I am considering either a 1:10" twist 30-30 win barrel or a 1:7" 30-30 win Ackley improved. 18" barrels.

Anyone here have experience with such a fast twist in a 30-30?
I understand that some guys want that twist for sub-sonic accuracy. I am not so interested in sub sonic, but I am in the 30-30 Ackley chambering.

I plan on primarily target shooting 1-200 yards, with the occasional deer hunt inside that distance.
 
There's no advantage to the 1-7" twist unless you're shooting very long bullets. Long bullets in a .30-30 aren't practical unless you have a bolt or single shot. Magazine length and throat length will be issues.

A 1-10" twist will work fine for a 220 gr bullet, but if you're loading for a lever, even a 220 RN will leave the cartridge too long to cycle through the action.

I believe the twist on factory Winchesters is 1-12", and it seems to work just fine up to a 190 gr RN.
 
Rregardless of type of action I can't see any real benefit to such a fast twist in the 30/30 improved or standard. As has been mentioned the original lever guns has 1 in 12 twist and worked fine with 170 grain loads.
 
Yes, the standard 1:10" should be fine. My last 30-30 win barrel was a 1:12" twist, and never shot to my expectations. I don't expect benchrest precision, but would like at or sub moa range.

Winchester used 1-12, Marlin used 1-10

1-7 is probably only going to be useful for Subsonic?
 
Hello guys! The 30-30 Winchester barrel my wife and I got was the standard 30-30 win chamber and 1:10" twist rate.

This barrel is 18" long, and heavy contour.
I was skeptical that this short tube would be able to reach any velocities near the top potential of the 30-30 win. But, I was apparently worried about nothing!

The barrel is unexpectedly accurate as well! What a bonus!
I have managed. 6 or 7 groups in the 0.3's to .6" range! The 168 grain Berger's are chronographed at 2250fps. Right were they should be.
I am hoping that these bullets will consistently expand at 30-30 distances 100-250yds +/- a bit.

This kind of accuracy right off the hop makes this combo really fun to shoot!
 
I'd buy a single shot in 303! I'm probably gonna get a Big Badger in 30-30, but I'd take 303 over that if it were an option. Sadly the only options for 303 that I know of are pushing $3k...

I would go with the 1:10 twist. I have a single shot in 30-30 and it'll shoot 5 shot sub moa groups at 100m with 168gr Amax bullets. It seems like it likes that twist rate.

Not to derail post but I’m curious which single do you have ? I’ve read 30/30 can be VERY accurate in the right platform .
