Serria 85gr Hpbt have a good reputation and cheap as.

Also the stabilizing thing is mostly bollox. Flat base 100gr 6mm bullets will stabilise in 1:10” 99.9% of the time no problem at all. If you use the Berger stability calculator it doesn’t have a function to take into account the length of the pastic tip, because Bergers don’t use them. And it will report “marginal” stability. Use the JBM calculator and the correct value for the plastic tip, and you will see values well above the all important 1.3. Load them right and shoot them and this will be proven to you.

I have all the measurements for the new 6mm Hornady bullets cos I asked Hornady for them.
