Dont worry, I just wondered why S100 was excluded. I checked the JSB website, it seems that they are no longer their match topline. Theyre now their heavier matchpellet whereas the Premiumline took its place as toplevel matchpellet.
Didnt even know they changed till yesterday (AGW piece)
I use JSB Exact in 99% of my 'hunting guns' and classics as well, I use the JSB match in all the Tau 7s.
Yes they often are deformed but they still perform best/very well
R10 I only use in the LG300. The other matchrifles all prefer domes
