Just wondering if pellet development has a better pellet for the BSA Hornet than the JSB exact Heavy?
I haven't seen a post from you for a while, but figure if anyone knows, it's you.
Beside which, I'm missing hearing of your exploits.
cheers, curan.
Sorry to turn up late Curan. I have been away these past weeks and quite a bit too over the last months. But I have been doing lots of shooting and related experimenting.
First to answer your question. No there are no better pellets for my BSAs than the JSB 15.9 gr and 18.1 gr ( 18.2) Exacts. A couple of days ago at the farm ( got back home last night) I had 4 hunting shots with the .22 BSA Hornet shooting at 875 fps with 15.9 gr Exacts. Three very neat head shots on three very healthy rabbits, 64, 66 and 67 yards and one big crow at 102 yards. As you know, I laser range find for every shot and adjust the sight turret to zero for every shot to the ranged distance.
Recently shot the .25 cal BSA Hornet JB OZ 1 against centre fire hunting rifles in our club in a 100 metre group shoot:
I shot JSB .25 Kings at 890 fps for this .77 inch ctc group:

Everyone had a little trouble with the fresh fishtail wind from behind switching from 4 o'clock to 8 o'clock. If you got it wrong the lateral spread was not good. I tried to pick it at 7 o'clock for the bracket above and got lucky.
Dave Eade ( who wrote the wonderful Chairgun Programme and now lives in Spain ) wrote me a special programme for the .25 Hornet after I did the velocity chronograph tests at 200 yards, 100 yards and 50 yards. It takes into account the changing ballistic coefficient of the .25 King Exacts as shot from my rifle as the pellets progress down range. It is so good that I now have to worry about the ambient temperature throughout the day !! Oh the woes of air-rifleman-ship
I can see one of those palm sized pocket computers in the future
My current interest has been in assessing pellet spin rates down range by shooting through two cards located at specific distances apart ( 12 to 24 inches) with marked pellets and computing the spin rates per unit travel ( and rpm also ). Very interesting now that I have data to 200 yards. I will make a post with the results and possible implications if there is any interest.
Have also been testing a new version of the 25.4 grain JSB .22 Monsters. This one has a slightly pointed head and is called the Monster Straton as its head is the same shape as the JSB Straton. They are shooting very well at 750 fps from the .22 Hornet and have allowed me some further insight into the differences between the diabolo shape and a more bullet like Monster pellet as far as wind deflection is concerned. ( More on that later too perhaps ).
Not enough time in this retirement phase of my life !! There is so much of interest not to mention hopefully another trip to Cooper's Creek to see the wild flowers after the big wet and floods and gearing up for more fly fishing to Tassie next Feb ......... Regards to all our great air rifle shooters here, Harry.
