Fenring asked in relation to the targets I posted yesterday ... "

Were the pellets straight from the tin?

Well yes and no ...... The pellets I used were straight from the tin but I had tested a sample of 50 of them on my " Yrrah roll test" that I devised a couple of years back. They came out very consistent in relation to the relative circumference of the heads compared to the skirts. I did not put them through any of the other discriminating procedures that I sometimes use when deadly serious...... These were the sample from this tin:



This is what you may expect from some other pellets:



And this is the best result I have ever had from a pellet:

...... but to be honest, unless you are chasing the "n th" degree of possibility, weighing and then sub batch "Yrrah roll testing" will do it. I wouldn't put anyone but myself through the whole bit ........ Kind regards, Harry.

Well that roll test is a new one on me.

That's 'cause I invented it ....... and named it the "Yrrah Roll Test"... you heard it first here ... Been doing it for some years now and you might be surprised to see the results.

There is a little skill in making sure they don't get kicked sideways to start them. It helps to raise a table leg a fraction if there isn't a natural roll. Blowing through a straw to start them or using a soft feather is better than pushing with a finger..... Check a couple of pellets a number of times until you get them doing the same thing each time. Any way its out in the public arena so if you have some spare time ha ha ha ........... Kind regards Harry.

Well Yarrh, they use a similar method for finding the corect bias on lawn bowls. They roll them down an incline and the ones that land in the corect box are the ones that get sold, the others get crunched up.
Another gem of almost useless trivia from Hilly's pile of almost useless trivia.
Briliant idea though! Is there any relationship between pellet weight and radius of curve or is it purely a combination of pellet head diameter versus skirt diameter?
Rather nice shooting too, it shows me that I have a long way to go.

I have not yet found a direct correlation between weight and roll test batching Dennis. So I would have to say that the discrimination is due to the head to skirt relationship only. .. To add a point here, skirts that have lots of little dings seem to roll in a shallower arc as they cut chords across the high points and so reduce apparent circumference . Pellets that have been carried around lots and bounced about tend to roll further down the ruler....... Kind regards, Harry.

So it may be wise to carry any pellets that are going to be used for some special purpose in one of those nice pellet containers that stores each pellet in it's own little hole so that there is minimal damage to the pellet skirt? Some of our 10M shooters seem to like that type of box but possibly because you can count the number of shots fired and each pellet is presented with the skirt upwards, ready for insertion in the loading port.

Hi Harry nice grouping there. I started with storing pellets individually in a foam block quite a few (many ) years ago after an enlightening zeroing session. Due to a few years club shooting I started the purse habit, but this year I think I'll revert to using foam as I've never been a great fan of the hft purses they use over here where pellet rubs on pellet.
