6.5 tcu ?

[goob]

Im shooting a 6.5 tcu in a savage 11 with a 24" barrel. Load is 30 grains h322 with 100 grain Nosler Bil tip. Im getting 2900fps average. With this small caseing (.223 rem.) will I loose vol. if i cut the barrel down to 18". I was thinking maybe I have burned up my powder and dont need the 24".

Goob i have a 6.5 grendel on a model 10 with a 20 inch barrel using 30 grains of blc-2 behind a 123gr bullet and seem to have complete burn. If i am correct H322 is faster than blc-2 so i would think it would give a complete burn.

Since the TCU rounds were designed for handgun length barrels, I don't think you'll have any problem getting reasonable performance from an 18" barrel.

You will lose about 50FPS for every inch you cut off. That would still give you 2600FPS out of an 18" barrel. Hope that helps.
