Rob it's the way Ryan services his with a hammer... the pellets are too scared to stray!

Lets face it, your biggest market for pileshovers and exterminators is the states where they're more bothered by power than accuracy and we all know bullet shapes work well at high speeds. Shuttlecocks work best at slow speed which is why none of the top shooters here use anything else.

I think you might be onto something Ryan. At medium ranges I suspect the bullet shaped pellets have enough spin to keep them stable. At longer ranges though, it's very likely that pellets are starting to rely more on drag stabilisation, especially in .177 given the lower spinning mass and the steeper fall-off of velocity than larger calibres. So the bullet shaped pellets then may start to tumble a little more, probably not drastically at first, just to wobble a bit like a slowing top. This would open the groups up a lot and knacker the BC making them very poor in wind at longer range.

Airgun barrels all seem to have very similar twist rates (about 1 in 14" I think).
In the US where powers tend to be higher, the pellets will be spinning faster and keep this high spin rate further downrange.

I wish someone (with deep pockets or preferably their own barrel plant) would experiment with higher spin rates. Is Ben Taylor on here?

In my tests, the problem with these pellets was the group size opening up because some pellets usually fell low. It was pretty clear that those pellets falling low punched ragged holes in the card, giving evidence that they had started to tumble in flight, up goes the drag, down goes the BC, and they hit low.

If a manufacturer talks the talk, the product must walk the walk. For me, even though they looked well made and have really good weight deviation, the rangemasters or defiants simply were not as good as the main competition in terms of accuracy. I, like many others would love to buy British and support Hugh, but not at the cost of reduced performance.

Build a product that works, people will buy it.

Can't believe I'm going to say this but I agree with Dave.
