More internal SA mag length!

Postby jdboy » Thu Jan 01, 2015 5:20 pm

I have yet to find a Short Action DTA magazine with the advertised 3" internal magazine length. I'm having trouble getting the longer bullets seated close enough to the lands. The advertised magazine length would be great but every one that I've had measured for me is closer to 2.90". And this just will not work with seating to the lands with MY factory .308 conversion.

What barrel are you using? A COAL of 2.90 is a good .1 longer than the DT match ammo that is used to give the 1/2MOA guarantee. Does yours not shoot well from that seating depth?

It shoot's ok with the 168's at mag length but when I tried to go heavier I just never could find a good node. The factory .308 barrel has proven itself to be very finicky. There is no factory ammo that I've ran through this barrel the will perform to 1/2 MOA no matter what the bullet weight. Although I have found a few of my hand loads that perform very well. This is an early factory Krieger barrel. My 300 Win Mag barrel on the other hand shoots well within the 1/2 MOA guarantee with factory match ammo.

Thats rough, I dont know why it would be giving you such a hard time. Do you know the round count on the barrel? That one has to be pretty old.

The round count was just north of 700 when I purchased the rifle. Since then I've ran probably another 500 rounds through it myself. Not saying it won't shoot, just saying it doesn't like factory ammo. I have a few pet loads that work great but one of them is a definite single feed load.
