The trouble with a 25 or 30 caliber is a lack of high BC bullets a quick look in any reload manual will show no .5 or above bc for 25. And 1 or 2 for the 30.caliber but in 7 or 6.5 wow 5 or more if you're hunting in those long beanfields you'll love those kinds of bullets. You can make a long range gun shoot a short shot easier than a short gun on a long shot. So I say go with the most new things out there that already did all the comparisons and most likely to accept the newer longer bullets that come out the next year you get your gun done... 6.5 PRC has my heartFor deer and antelope try a fast twist 25 caliber. Always fun trying something new. I’m really enjoying my 25-284 with a 1-7-25” twist Helix 6 barrel. Shooting the 131 BJ at 3150 FPS. Just waiting on a heavier Absolute hammer to be released. Hopefully they will have something in the 125 gr range. Very little recoil with a high B.C. bullet take the 25 caliber to new levels.
