This was originally posted in the pic section, it really belongs here. Basically doing a copy and paste. Sorry for the confusion.

Very new to Dan Wessons, with 1 range trip on my new-to-me 15-2 with a
6inch barrel. It's absolutely full of lead, it came that way. After
hours of cleaning I took it to the range anyway, it shot great.
I looked at just getting a new barrel when they are back in stock, but thought the fast twist was, different.

Is there another page on the EWK site with standard twist? If I'm
just confused please let me know. If it isn't standard, why such a fast
twist rate?

I did some searching but couldn't find the answers.

Thanks for any and all help.

There was a reply and last my reply, confusing... it's all pasted next.

I should let Eric (EWK) respond… but I will throw this out:

Stock DW 15-2 was 1/16

So far EWK have been 1/12

So whats the diff: the 1/16 is supposed to be the best all around
twist for small faster bullets so a 125gr bullet moving 1400 fps such as
found with a standard self defense .357 round.

I on the other hand, shoot mostly 158gr bullets moving 730fps. the
"fast twist" barrels (according to google) are better for this round.

I am not familiar with any DW pistol barrels at 1/18… which would be a very very slow twist rate.

Soap Box, Ballot Box, Ammo Box

in that order.

Final reply:

Thanks for the info. I had the understanding that the 16 twist rate
for handguns was to allow for heavy bullets, or long bullets. Even
auto bottom feeders standarized on 16 inch.

However some revolvers come with 18.75 (Rugers like the GP100 do for one), while Colt Pythons have a 14 inch twist.

I believe the 168 grain Keith will stabilize with a minimum of 25.8
or so. A 125 should I'm sure requires something much slower as it's a
shorter bullet, like 30 or 35. (just guessing as I don't know the bullet
length)

Pure speculation is that the extra RPM with a heavy bullet may stay
stable longer and provide good accuracy at a longer range. The light
bullets slow down in velocity and RPM much more quickly. Losing
accuracy. Maybe. Smile
