18" Proof Research - 6mm ARC build and testing - factory and handloaded ammo
#24
I just got off the phone with Hornady.

They are not completely putting ODIN and Proof in the hot seat - the tech says they could stand to shorten the COAL for the 105 BTHP Black ammo.

He says what most likely happened is that Hornady sent “high speed reamers” out to barrel makers, these reamers are good for only 10-15 chambers (they are non-carbide).

It may be that these gun manufacturers went in to full production with these high speed reamers and so early runs of barrels can be short or tight in the throat.

He says I can seat the factory loads deeper to use what I have and I said no thanks.

He said maybe chasing the throat with a carbide reamer will fix my barrel and I said I wouldn’t want to do that to a 500 barrel.

So now waiting for proof to respond....

Update again - proof responded , they don’t have any 105 BTHP on hand to test barrels with, they requested photos of a chambered round which I will send to them shortly.

Meanwhile....  I talked to another barrel maker who is working on a barrel for me and they said they’re aware of the “issue” and they think the bullet diameter of the 105 grain BTHP is towards the higher end of tolerance.....

Continuing to trouble shoot this .
