    243 Velocity Chart for Barrel Length

    I am looking for a velocity table based on barrel length for 243. Realizing velocities will change based on twist and ammo used. I will need to cut it down a couple of inches to thread it and place a muzzle break. Fortunately I believe it will be a great deer gun for my 6 yr old.

    Ballisticsbytheinch.com has velocity data for .223. Should be similar velocity loss per inch for 243.

    The 6.5CM im looking at has a 22" barrel, threaded. Will adding a muzzle brake add "length" as far as going off of the chart? I wouldn't think so, just double checking..
