Canik TP9SF barrel twist rate

I have looked through many pages of search and search engines but cannot seem to find a definitive answer as to what the twist rate is. No not just stick a cleaning rod in either as I'm pretty certain it's metric, and I need real numbers.

Perhaps I didn't hit on the correct words, but short of contacting Century on Monday and waiting however long for them, does anyone have that to share? I find it very odd that such info is not readily available.

Building accurate powder models.

Never gave it a thought. I have 3 Caniks. I love them too. I have to load copper plated or jacketed for them though. Cast leads mine up for some odd reason. Curious as to why you need to know the rate of twist?

I tried cast years ago and after scrubbing for hours getting the lead out I never did it again. Yes there are millions who will swear by it, but not for me thanks.

I use Berrys/Xtreme/Speer copper plated. I have not yet, but powder coated cast bullets I could be talked into trying.

American Rifleman.org article from 7/15/2017 (NRA gun of the week) shows Canik TP9SF twist rate to be 1:10 RH.

Thanks I did see that.

I have doubts it's a accurate number though. 1/10 is common for imperial but suspect in actuality it's 1/250mm (9.842) and was rounded off to 10in.
Contacted Century and got a canned response so I don't know what else to do except wait for them and keep digging.

Speaking of digging, I have to go clean yet another nuisance 4in of every other day snow from the yard.

I'm sure both work fine and I like the looks of Bullseye but Titegroup burns out far too soon for my taste, and with a target velocity of 1150fps pressure is all but maxed out. That is of course a based on a simulation and does not reflect actual results, but I find it a very useful tool.

I have recently found the need to switch powder, hopefully for the last time, after running the numbers with a 6-8 different powders I wanted to use CFE Pistol, yeah good luck with that.

My neighbor told me he thought he saw a pound at the LGS so when I got there of course they didn't but they had 2 pounds of WW Autocomp. Some say it is the same powder with a different label which I hold zero stock in, but it has essentially identical load data and it's right next to CFE on the Hodgedon burn rate chart. So I grabbed them both and hid them under my coat in the parking lot until I got back to my truck.

The model I have shows complete burn within 10% before or after leaving the muzzle for my two barrel lengths respectively, a velocity of 1164/1092fps and pressure at 26259 which is almost 25% under max so it should be a good shooter. All I need now is to load some some test rounds and settle on a load if it ever stops snowing every other day... jeesh

.Century did finally get back to me with 1/6 twist rate number.

That would coincide with running a bi-metal jacketed projectile, and the overall premise of them when they were introduced, along with where they are made.

Not believing it really was 1:6 I finally stuck a brush in and measured 2-1/2" on the cleaning rod and came up with bascically 1/4 turn. So whatever it is it's close to 1:10. I suspect it is really 1:250mm but whatever, I'm sick of messing around and find this incredibly unbelievable there is no way to find out what it truly is.

I am in load development stage, so I wanted accurate numbers to put in my powder models to get the best simulation possible. Actually I finished and ran the numbers the other day, then made some min/max test rounds with 115gr and 124gr, Now all i need to do is shoot them, load the chrono data and study the results. After that it will be a matter of finding the sweet spot for the pistol.

I bought mine 5/6 years ago before any of the places around here had even heard of them, since then I have had little chance to shoot it but it eats everything I've tried so far with zero complaints. The trigger throws me off for the first couple shots because my other pistol triggers are so lackluster it catches me by surprise.

Anyway, I hope to get into it a lot more as the weather cooperates.
