90 gr swiss by volume you mean , right?52Bore said:I believe it was 46 or 47gr by weight that gave the same velocity (Chrono) as 90gr Swiss 2F by weight. Using a 525gr GG
I wasn't shooting, but was there to witness.
Start low and work your way up..

axischem said:Today I went out and shot my Knight 45 cal 1/20" with the 80 gr/v BH209, 500 grain PP Buffalo bullet. The breech plug I use is a Lehigh with the removable vent liner. To help with the primer concerns ( primer pressure signs and erosion ) I had the vent liner platinum lined leaving a .026 diameter flame channel. The gun shot flawlessly with this modification of the vent liner. I still may lower the the charge amount, but the groups are fantastic if I do my part. Recoil is considerable to say the least, but still not a problem to me. Winchester primers are holding up the best of any primers I have used in the past. Federal being the worst.
