Text me for pics of reamer and whatever info I have. 4804678090
These are good live pilot finishing reamers with 10-15 uses on each. Plenty of life left. Hell I don’t even like reamers until they’ve cut 10+ chambers.
I bought these at the start of my career about 14 years ago and back then deferred to the tool makers suggestions or just bought a saami reamer. Now all my reamers come from JGS and they mark the shank of each one with critical specs. Having every detail lasered onto the side of your reamer is priceless… but 14 years ago I hadn’t realized that yet.
Reamers should be saami minimum body, and in most cases a saami fb/throat. You can often look at the throat grind and get an idea of how long it is, and 1-30 seems to be the most common lead angle by far, so I can usually look at a reamer and have some idea of its throat dimensions.

Looks like a shorter saami throat, should be fine for 300wm factory ammo.

Looks like a typical x47 throat… like .150” fb

This reamer has its specs printed on it
338 Lapua mag PTG
$60 shipped
box says T23218 from PTG. It built some accurate lapuas 10 years ago but I can’t guess the freebore dimensions by looking at this one. It looks pretty long, like .160” fb or so, which I say is long because of the magazine length restrictions the 338lapua faces. 3.850” just ain’t long enough with the 300gr berger elites unless you have very little freebore. The older 300s and the 250s/285s seemed to easily fit 3.850” with some throat length and still reach lands, but lately with guys shooting the 300gr Berger elites I’ve had to use my shortest throated Lapua reamer(.070”)
