You can expect additional muzzle blast...but the in cab portability will be nice..

My 25.5" 20 PT runs 40 moly V out at 3900 fps....why 25.5" ??

The barrel was a 204 R for a short time....then rechambered to 20 PT...

Awesome cartridge to say the least....I prefer the 40s over the 32s

for better downrange performance....std 223 load of 26/H4895 works

very well in mine...new handle Jim ?? Haven't see ya around here in a while...
