Author Topic: 7-30 waters accuracy and velocity in a ... (Read 1494 times)

What velocity can I expect to get from a 16 inch carbine barrel? How much faster will the 7-30 shoot than the TCU in a 16 incher?

Also what kind of accuracy is this cartridge capable of from a carbine setup. I've read that the 7TCU is super accurate. Should I be able to get 1/2 to 3/4 MOA out of the Waters? Just posing questions at this point.

Picked up the barrel at a gun show and haven't had a chance to take it out to the range yet to see what it will do.

Thanks,
Brad

You can typically expect a 150-200fps increase of the Waters over the 7mm TCU. As far as velocity out of the 16" barrel, you should be able to get a 120gr bullet over 2400fps with the 7-30.

With a good load, I wouldn't be surprised to see sub-1" groups at 100 yards.

I do not have the 16¼" but I do have the 21" in 7-30 and I get 2680 fps with 120gr. Sierras, and I get 0.75moa with this load. :grin:

Kirkned,
Care to share the powder used with that load?

I've been contemplating a 7tcu or 7-30 waters (in a pistol barrel - 14") also. In my studies - according to my Nosler manual the 7tcu actually has more velocity for the same weight bullets......maybe in a rifle barrel the larger powder volume will have a chance to burn, but in a 14" barrel the 7tcu seems to be better. - At least according to that manual, my other manuals all have the 7tcu from a 10" barrel and in those it gives up about 150 to 200 fps to the longer barreled waters.

Hi all 7-30 shooters, try Hodgdon "Lil Gun" great powder, good velocity. & lower pressures than H-110 . .Mack

Mack you use h110 and L'Il gun in the 7x30 waters. Where you get this load data. That is mag. pistol powder. Best powder I've found is IMR3031 .
