What should I expect as reasonable velocities using 400 grain cast in 8 3/8” 460 XVR? Cor-Bon advertises 1525 fps with 395’s. I’m getting a little over 1400 🤬 with my 400’s, with very difficult case extraction! I used a wooden dowel to drive the cases out, as to not risk damage to the firearm.
So far the powders that I’ve tried are AA1680 and WW296. I didn’t want to try LilGun because of lots of bad press!
I do not have access to another chronograph to verify velocities, but this one appears to be very close with other firearms......so, I’m thinking this is a representative velocity.
Soooooo, what should I expect for velocities? I would be OK with a solid 1400 with good extraction. I’m not opposed to some resistance to case extraction.....but, this is a bit much! 🤬
Thanks for any and all comments.....even the less than agreeable ones! 😁 memtb
