Reloading for the new .277 Fury from Sig

I'm always scared that I'll be the "dummy"……find it later, thinking that somehow I failed to include it with my last loaded ammo!

Then use it on the best, biggest trophy animal I'll ever see! 🤦‍♂️ memtb
I do need to bump up my load. I used 39gr of BL-C2 and only getting 23xx-24xx fps. I went pretty conservative. (Range 36-41.2) My next loads will be 39.5 & 40gr.
 
I just looked back at the data from xxl-reloading to make sure I remembered correctly, but they were waaaay off, at least with my rifle. I can't remember the barrel lengths they used, but I'm running 16" and just a bit under 80k, but below for sure. If I used what they had suggested I'd be around 2200-2300 fps. They are very conservative, it's a reference for sure, but they seemed so far off, it wasn't really even a reference. Use some of their powder/bullet combos for 308 or 6.5 and compare to what several other books have for max and min in those calibers. You will notice xxl-reloading is completely different. Their max, it seemed was as much as 2-3 grains of powder or more below what other manuals listed.... and 2-300 fps slower too, which would seem obvious. Moral of the story was that their max pressures didn't line up with any of the other reloading manuals I had. Just FYI and something to research.
