    Great idea! 
 Gawd dam right tool wrong tip. 

 Whats the dimension of your bullet tip? Might be able to cut lead off top. (after I separate the powder and fire primer)

	For the odd bent skirt I use a dummmy 308 round with 130g speer hollow point projectile, which is perfect for pushing the skirt back into shape. Quick & simple. Edited by flock - 20 Apr 2024 at 5:36pm

	Sigh one more thing to check. Time consuming, not fun, always interesting, amazing some of the tins I've had,especially the cheaper ammo, why I gave up on gamo pellets. (Though the red fire and one with ball bearing in nose have always given me good results (but never the best). Still if I'm hoping to constantly shoot from 60m to 90m accurately better get rid of all the variables, so I can adjust what I'm doing and not blame a pellet for bad shots.

	Good observations. A point I learnt was that when fired, the air pressure from a springers piston builds behind the pellet until the pressure is enough to propel the pellet and parachuting (expanding) the skirt. So if there is a gap around the skirt, pressure will bypass the skirt. In a pcp, the pressure arrives instantly, parachuting the skirt against the rifling straight away. So a good fitting pellet in a springer is vital.

	Maybe I should be looking at skirts as previous asked. Found an artical while looking for head sizer. Quote: The pellet head need only lightly touch the lands, so that the pellet doesn’t tip back and forth on the way down the bore, but the pellet’s skirt must cut into the rifling to effect an air seal. In springers, the skirt has a very important second function, as James has pointed out. It interacts with the chamfer at the breech end of the barrel. Together with the pellet's weight, this determines the point in the piston’s travel, at which the pellet begins to move. If the skirt is too small, the pellet takes off too soon; power is lost and there is a minor “slam fire” effect on the piston. If the skirt is too big, the pellet will linger too long and the piston will bounce, again wasting velocity and making more felt recoil. There is a lot of variety out there both in pellet skirt size (I’ve measured anything from .180” on Crosman ammo to almost .190” on some traditional RWS designs), and the breech chamfer detail (many guns today have a short, sharp-edged angled cut, some have a more carefully designed longer taper, some are in between). IMHO experimenting with different ammo to match up skirt size vs. breech fit, is a really important part of shooting springers. It can have a huge effect on accuracy, consistent velocity, and firing behavior. It’s long been curious to me that pellet weight and head size seem to get the lion’s share of discussion, while this aspect is rather ignored.

	They are not! I've already had one mishap with them, so put some cardboard inside of the joints. Want them movable till I sort out what head sizes and weights do what. Then I'll reorganise the partitions, line the bottom and glue them in.

	U sure have been busy! I hope those little yellow plastic dividers are glued down to the bottom of that black container!
	Walk quietly, but carry a big stick.

	Yes it is. A flyer doesn't worry about minute of rabbit head. Deviations amplify over distance. I'll shoot out to 70m once I get better take that out to 80m. There's a photo in "you got to be out there to see" , of a rabbit I shot with the tx200. It also shows the pellet from the gamo I had which I removed from it's back leg. I rember the shot with gamo. It was a clean well placed head shot. I thought I had missed it as it ran off. I can tell you now that the lighter weight pellets and differnt head sizes will affect poi. Further you get from your bore size the worse it gets for head size. Weight and drop is pretty self explanatory. Finally it's a living being, why wouldn't I take all nessary steps to minimise the risk of wounding a animal and putting food in the bag. Target shooting pellet prep is ideal for hunting. One shot kills is what I strive for.

	I have to congratulate you on the amount of effort you put into this sorting. I have to ask though, is it worth it in a hunting situation where minute of rabbit head is what's required? I can understand, maybe, the value of it for 50m benchrest.

	So thought I'd throw up a visual instead of numbers. 1500 pellets worth. Up to at least a dozen damaged (mostly due a slight misshap while sorting.) Pellet weights of tins went from 1.01grm to 1.06grm. The 1.01grm I haven't sorted as need another container, also starting to get lighter than I want. 1.06grm goes left to right 5.51,5.52,5.53mm head size. The pellet box is from top to bottom is 1.05grm,1.04,1.03,1.02grm. Left to right, head size 5.50mm,5.51,5.52,5.53,5.54,. This is the full range of head sizes in tins. (1.01grm not sized yet) If you ever wondered why you get Flyers! Over all I'm really happy with this. I've had bigger spreads and head sizes out of a single can before. Take note AA and hades not to even start on h&n. I'm after 5.53mm head size so stoked so many threw over 5.52mm though I'm hopeful the 5.52mm/5.54mm will be as acurate as well. I've already determined that the weihrauch seems to like the larger head sizes to the smaller.
