25 GT 10 Twist

[806 Guns]

25 GT 10 twist
Built for 70gr Blitzking
75gr vmax
95gr Mcguire Ballistics Copper Rose

Using Alpha brass in my 24" barrel i got to 3540 fps with 8208. Going to try some H4895 too

Current barrel is a 22" 1:10 wilson blanks
25 gt PTG reamer .128 freebire

Oal with 70gt blitzking is 2.432"

Loaded these to 2.320"
Long neck and short bullets leave lots of jump in this type of reamer made for target bullets.


Here is speed with SW Match/ Accurate 2520

3547 fps at 65 degrees
Shot a .75 group and will get better as the barrel gets broken in. I call it a modern 250 Savage.

Would be interesting to see if there is any throat erosion. Love that speed.

Im guessing it may take a few hundred rounds if something shows.
