The Ultimate Guide to FX SLUG LINERS deffo worth a watch if you're the slightest bit interested in slugs.

As I said on another forum (and was accused of being arrogant by a fan boy) I do wish he would check his facts on basic aerodynamics and external ballistics before making statements or presenting diagrams which are fundamentally flawed. It makes one wonder how much of the other data is also of the same standard.

Have you ever experimented with different twist rates/grooves?

What according to you would make the slug guns accurate?
I'm just curious like.

I recall BB has played with some much larger calibres

Slug guns can be accurate but you need to match the bullet to the rifle. The twist rate needs to be sufficient to provide stability but no more. Too much twist will reduce accuracy not improve it through making the slug slower to react to problems because of excessive stability.

I watched the whole video and it seemed very interesting, can you let me know what statements he made were wrong ?

Please don't think is a pop at you as it's not but would be interested to know, feel free to PM if you prefer

Many of the problems stem from the previous video on pellet stability which he attributes to drag. Pellets are not drag stabilised so any diagrams or statements based on that premis are incorrect. There are also diagrams showing airflow at right angles to the pellet producing Magnus effects which give the wrong impression, the diagram at 37.50 is particularly bad. This is just one of a number of points, some minor and some not so minor but most of it comes down to his basic lack of understanding of how pellets fly.

1000mm is the largest calibre I have had to deal with (no prizes for guessing what that was involved with). In practical terms 155mm was the usual maximum.

Thanks for explaining, ballistics isn't an area I know much about so it's interesting to hear from someone that knows

Edit: Have you done any videos ? Be interested to watch if you have

If I made a video it would become compulsory watching for insomniacs.

I'd still be interested if you decided to do one
