New Digital Powder scale and JSB .22 Jumbo Heavy pellets
Posted: Wed Dec 17, 2008 6:22 pm
Just treated myself to a "Smart Reloader" SR750 Digital powder scale. I have a RCBS beam balance scale but I thought I would update a bit.
My first weighing job as a try out for the scale was to check the weights of a tin of the new JSB .22 Jumbo Heavy 18.1 grain pellets, with a view to do some long range plinking and taking Harry Fullers advice I got stuck in.
The factory stated weight for the pellets is 18.1 grains,the tin of 250 pellets came out as follows.
Approximate estimate of 50% were right on 18.1 Grn; 49% were 18.2 Grn,18.4 Grn,18.5 Grn and 1% were 17.7-17.9 Grn.( This would of course vary from tin to tin).
It was an interesting exercise and a little of a surprise for me on the variance of weights,but, in the mass production of the pellets it is inevitable that the weights would vary due to methods used. You just cannot hand make them.
So I have my weighed pellet batches Long range here I come.
Later Ray.
