Thread: What to do with my Omark ?

Been talking to gundoc and Jaco Goosen, but keen to hear other opinions as well.

The bolt face does not have a lot of meat, so I am stuck with .470

H2O case capacities:

30-284 : 66.2gr
30-06 : 68.4gr
30-06 AI (assuming +5%) : 71.8gr

It is a single shot, so no mag length issues to complicate matters, and if I need to, happy to pull the bolt to get a loaded case out.

Guess what I am after is a 470 bolt face 30 cal chambering that would allow me to send 200gr + projectiles downrange as fast as possible.

Any better ideas than 30-06 AI ?

What to do with your omark?

You should shoot it, admire it for its simplicity but great accuracy and hug it every day. I saw a sticker on a guncase once that said "have you hugged your omark today"....it would be a full time job for me!!

Have you thought of rebating the rim of a larger calibre? 300wsm perhaps? I'm not absolutely sure if you could go that big but maybe.

When you say "rebating the rim" do you mean opening up the bolt face diameter ?

If so, nope, not enough meat left on the Omark bolt to go any larger than .470.
