Here’s a picture of the rifleIs the M78 the one with the pinned in barrel?
Barrel length of the M78 is 560mm or about 22". Twist rate was 1 in 16" for the Hornet, but many of today's newer Hornets are coming with a 1 in 14" twist. Either way you can measure the twist but both will stabilize any bullet suitable for use in the Hornet, which is 35 to 45 grains. Groove diameter is .224" & land diameter is .218" making the rifling depth about .003", which is standard for any 22 centerfire barrel.Hello,
I don’t want to buy this rifle for precision. For that, I have very good weapons! It is intended for the fun and learning of my grandchildren. I’m just looking for information to enter into the Gordons Reloading Tool to develop a reload.
Barrel length and twist, as well as the diameter of the stripes

Thank you very much for the information.Barrel length of the M78 is 560mm or about 22". Twist rate was 1 in 16" for the Hornet, but many of today's newer Hornets are coming with a 1 in 14" twist.

With the hornet being my favorite caliber and having carried one as my truck gun for about 50 years I learned that the common 16” twist found in most hornets does not stabilize 40-45 gr pointed bullets very well. 14” twist is much better for a hornet. My 40 year old Kimber hornet w/14” twist has the first 3” of the barrel eroded (yes we all shoot it alot) and still shoots 45 gr Sierra spitzers lights out.Barrel length of the M78 is 560mm or about 22".
