Bet ya' thought I don't know how to spell popular, eh?
Nope, it's the wood used to assemble a diagnostic tool.
Couldn't figure out why my new 455 Varmint was so inconsistent off the bench.
Receiver is pillared and bedded, but groups just weren't as tight as expected.
In fact the first trips to the range, they were pretty sad. Happened to have a chunk
of 3"x3" poplar in the scrap box, and with some odds and ends off the work bench
and parts jars, assembled this...
Ran a 7/8 inch channel down the top center of the block of poplar.
Sanded to rough the inside of the channel, then epoxy bedded a 0.866 diameter CZ barrel in place.
Using metal plates, zip screws and some scrap leather, clamped the barrel in position.
Mounted my work bench vise on a couple chunks of 2x10's and clamped it on the shooting bench.
Ran a variety of ammo down the bore, Fed 36 gr cphp, CCI bulk Blazer, CCI SV, SK Pistol Match and Lapua Midas +
Problem isn't the barrel, the better the quality of the ammo, the smaller the groups. Midas+ produced 1/4 to 1/2 inch groups.
And that was on a day with wind gusts to 20. Had to wait for lulls to be able to shoot.
So much for the free floated barrel theory, CZ should of free floated the receiver and fastened down the barrel.
