Just some feedback:
I recieved my slugs today, and they look great!
Unfortunately, my setup is against the heavier slug, which I am only able to push to about 840 FPS. This seem to probably be a better fit for the Impactor simular airgun that is capable of making much more power.
Something I has noticed in both my Airforce airgun and my Mrod is that they seem to not like the flat nose slugs as much as the more pointed offerings.
I guess I will have to stick with the lighter slugs. I am also not sure if there is a part of it due to the increased engagement of the slug with the rifleling.
Gun used was .22cal LW equipped Mrod.
Keep up the good work!
