Pellet weight variance question

[Jeffery8mm]

My daughter is involved in 4H shooting sports, 10 meter air rifle.  This is our first year and so far we are doing well.  She has a Daisy 953. My question relates to the pellets.  How much variance is acceptable , or is going to make a difference at 33 feet.  I weighed a batch of pellets on my Pact digital scale and all ran from 7.8 to 8.2, with most being under 8gr.  Am I being too OCD?
Thanks
Jeff

I never bothered to weigh them, but in your case, shooting match, that's almost a .5 grain difference in weight, I would think it would cause some vertical stringing. I'd either weigh them and stick to shooting the ones that I had the most of, or better yet spring for some really good match grade pellets and go from there IMO.......................steg

most of the hunting/ better pellets it not so much. I don't remeber but in the USA air rilfes book they listed all the pellets and most were 7.9-8.0gr so not very much. Some like the crosman wadcuts they all are the same or they used to be. They gone down some over the years. I used to shoot a cromman 2200 mag with daisy 22 wadcut pellets and from sitting it would shoot hole in hole with those pellets.

The Gamo match  Diabolo 7.71 pellets are showing ALOT of promise
