That’s crazy. I shoot my 9mm 160s in the mid 800fps - zero recoil. I do have quite a bit of N105 for 300blk subsonic bolt loads. Maybe I’ll try a few at 5.5 and work my way up. Is that more of a subgun load or are you actually shooting 1020fps out of a semi auto handgun ?BEST 9mm SD is going to be a 147gr HP under 6.9gr of Vihtavouri 3N38, it shooter a 147gr 9mm HP at 1207 fps out of a 4 inch barrel! That's 200 fps better than Blue dot or long shot. I emailed Vihtavouri and asked if it's a +p or +p+ and they told me NO it's a standard load. That 3N38 shoots a 147gr like anything else shoots a 115-124! And if you want to turn your 9mm into a .40 their N105 mag powder will shoot the 165gr Xtreme 9mm at 1020 fps with 6.0 gr CHECK OUT VIHTAVOURI web site for their load data!!!
