I can't find the size on the box, but the 177 cal.jsb,10.34 gr. are giving me one hole 3 shot groups at 10 yrds. they group much better than the 8.4 gr. out of my ruger air hawk
Have you ever used them? What was your findings with them compared to 4.51 and 4.52 heads. Stilltrying to find "THE" pellet for my gun. Thanks Craig
Got 4 tins today to try out if the wind doesn't kick up. Ed, I have found your findings on every brand of pellets. There is only .0004 between4.52 and 4.53. For most shooters, that is hard for the to measure. This is what I made to do the job. 3 point contact.Thank for all your input. Craig
Ned, you have one to many zero's ".01mm" = ".000393700787402." But who is counting. LOL Craig
