Twist of barrel on Kibler Kit?
« on: April 17, 2019, 03:25:50 PM »
I am about ready to start shooting in my Kibler 58 cal and realize I am not sure of the rate of twist.
I can't find it on Jim's web site.  On the Rice web site I believe it says 58 cal is 1 / 66.
Does anyone know for sure?
Thanks

Likely is etched into the bottom of the barrel.

Cut and paste from the Rice website.
TWIST RATE:

32 and 40 - 1/48
45 to 54 - 1/66
58 and 62 - 1/66 - 1/72

NOTE: Other twist optional at additional charge of $30. Delivery time may be extended.

Thanks to all,
Like I stated, I saw that on the Rice sight but wasn't sure if that meant there was a choice between the two.
Now I k-now for sure.

Either/or - wouldn't make any visible difference in accuracy or powder charge.

I have had .58's in .48", 66" and 72". I thought maybe 56", but am sure it was 48".

One 48" twist .58 liked 85gr. 2F right to 100yards. The other preferred 110gr. 2F.
The 72" .58 preferred 120gr. 2F and the 66" .58 needed 140gr. 2F. In the days of the
slower twist .58's I shot nothing closer than 50 yards and 100 generally.
48" --- largest range of preference - 25gr.
The other 2 twists seemed to depend on the barrel alone. The trend for more powder was there of course.

I am just trying to use as little powder as possible and still get the best group.
I have one I use 60gr FFG in and its fine.
My friend has a rifle withan Ed Rayle 58 cal barrel, 44" and uses 80 Gr.  I think that is also 1/66.
Thanks for all the in-put.

If all things are correct the volume of powder should change little more than the point of impact. Naturally each barrel is itself unique but I find in most cases quality balls and consistent loading techniques will absolve many problems. I see many using e greatly excessive powder charges especially in smaller bores because the rotation velocity created by the larger powder charge volume is trying to correct projectile problems. I shoot with a man two months ago who was using 50 grain charge in 40 caliber. He needed so much powder because he was using ram rod like driving piles. I help him change patch material so loading is easy, now rifle shoots excellent with 25 grain charge as it should. If one pounds ball in with hammer or drives like a pile, ball is no longer round it is a bullet.

Thanks guys for the in-put.  This Rice barrel shoots so well that next time out I am going to try lessening the charge a little.
My little range is only 60 yds, but that's as good as I can see. If I can shoot without much ball drop at that, I'll be very happy.
