im new to the forum, but i been reloading since 1987.
im experimenting with how far i can take a long 270 winchester.
59 grain case
3.50" COL
magpro AA4350 and 24n41
cci 200
27" barrel 7 twist
bullet touches up at 3.89" COL,so .390" freebore
150 ablr and 170 ablr
what i have loaded so far. 150 ablr with 62 grains of magpro. 2898 fps average. no case stretch measured everywhere comparing
55 grains to 62 grains.
i am going to shoot 170 EOL, 170 ablr, 175 TGK, 155 barnes, and 150 ablr using the 24N41 primarily. i intend to add .010 more throat for a full caliber and a half freebore. its my standard for barrels i oreder in all calibers.
thank you.
