Palma freebore

[dcali]

What are guys using for freebore in .308 palma rifles these days?

 

[Erud]

I don’t get real deep into the finer points of reamers, so when I needed one for Palma, I just decided I’d get one that I knew a lot of good Palma shooters used. I went with the 2011 Fullbore, as it was in stock at Grizzly when I needed one. I think that’s .050” freebore, but not positive. It’s worked great for the last 7 or 8 barrels shooting 2156’s and Berger 155 Hybrids interchangeably.

Good luck,
Erik

The free bore on the reamer is .050" with a one and three quarters degree throat angle which works with the “new breed” of 155 – 155.5 gr. 30 caliber “Palma” or “Fullbore” type bullets. The body on the reamer hugs close to the minimum SAAMI .308 Winchester body dimensions, but with the neck set at a .3445" diameter and the free bore diameter set at a .3085" diameter, so as to comply with the ICFRA international rules. The reamer tolerances per the print are on the tight side (i.e. “Hold + .0002”).

lots of reamers to choose from for a Palma gun, mine is a variant of the Mid Tompkins design, it has a very short freebore (.015) but a shallow 1/2 degree lead angle, I've used it with the 155 VLD's the 2156 and the 155.5 Bergers as well as the 175 Sierra and Berger LRBT with excellent results.
