Scenars used to be "THE" FTR bullet, but to be fair you would always weigh them anyway.
I have never used PPU match bullets in 7.62 as I am wedded to Optimus HBC as being about the most consistant, well priced 155gr HPBT bullet out there. No doubt when I get my BAR10 I will see what si acceptable for CSR and load accordingly. At 100/200 yards it wont batter much.
As regards the .223. I won a gold in the post 55 SO 100-300 Phoenix this year with their 75gr HPBT at £19 per ton. They were £14 but apparently that was a mistake....Bugger!!
At longer distances, well I am a reasonably good shot when I get the wind right.... I could not tell them from 77gr SMK at 600 and have had soem good results in the Imperial this week
IF your rifle likes them and they are within limits for what you need, they are a good bullet. If they cost £80 per 100 and shoot like shite, find a cheap bullet that works
