Yes, I’ve tried the Barnes 150 grain TSX fn and was getting around 2280 fps from almost max load as the fastest shot, but I couldn’t really find anything very accurate.
So I’m going to test these out, and I think I’ll be able to get more muzzle velocity and hopefully better accuracy. Fingers crossed.
I shoot right now the 160 FTXs and those are wonderful so I’m hoping that the Monoflexs will be better.
This is a reply from Barnes after I emailed them about velocities and expansion;
“
The 30 cal 150 gr TSX FN FB will hit full, double diameter expansion down to an impact velocity of 1600 fps. Our load data
https://barnesbullets.com/content/barnes-loaddata/rifle/308/30-30-Winchester.pdf uses a 24" barrel. I'd subtract 100 fps for your 20" barrel. If I used a moderate MV of 2050 fps, 1000' elevation (average NY state altitude) and 32 deg F (cold NY Fall morning) I'd call 110 yds the max yardage you should try a shot. Depending on your loading skills I would think 2200 fps is achievable which then pushes the max yardage out to 145 yds.

So I’ve reached the projected 2200 fps but as I said I just wasn’t happy with the accuracy yet.
