I recently bought a new-but older-CZ in 458 Win. with the American, laminate stock. It has been neither bedded nor cross bolted. I asked a CZ rep about it who replied that " 416s require cross bolts but 458 wins do not." Hmmm.! I've read enough AR wisdom to doubt that.

So I bought an acra glass bedding kit, and will try my inexperienced hand at bedding soon.

As for cross bolts, I also have a Brownells'"Stock Repair Pin Kit." I'm ashamed to show my ignorance, but will the 3/32" pins in this kit serve as cross bolts or are they much too small?

Thank you . Please forgive the smallness of my knowledge.

Those brass pins are too small, soft, and flexible.
They would be used for reinforcing epoxy repairs of cracks in areas not involving the primary crossbolt sites fore and aft of the magazine box.

Get some real cross bolts.
Placement requires precisely aligned through-drilling of the stock,
best done with a jig to assist.
If you have not done that before, get a gunsmith to do it, for the exposed/visible cross bolts.

Or, something that anyone can do, and just as good, hidden cross bolts, use buried/hidden pieces of allthread that are steel and 1/8" to 3/8" diameter,
whatever your skill and the stock wood allows,
the bigger the better:

1. one behind the primary recoil lug, bigger is better
2. and the other in the web between the trigger well and the magazine box well, smaller if web is thin.

Dremel out slots to lay these in, then fill and cover over with epoxy, then finish the glass bedding.

Before you get too carried away, get a gunsmith to have a look to see if the areas of the action that need support aren't already abutting the stock. Also if there is clearance around the tang and trigger. If the stock fits, then you will only be replacing wood with beding compound.

If the action is seated properly and the stock is not up to the task then you will need to replace the stock.

You always run the risk of a gunsmith selling you a bedding job you may not need but a good one will tell you what is also right.

thanks

FWIW, there are seven ACGG stockmakers in OR whom you might contact for help.
