I have three 6 Norma Dasher barrels that have been cut for a Mausingfield (M5) with a shoulder. Brux Target Contour, 7.5-twist, 26” long, 6 Norma Dasher with 185 rounds and 5/8x24 muzzle threads. Bead blast finish. (shot the 108 Hornadys excellent – the only bullet I tried in this barrel) $225 shipped Bartlein Marksman Contour, 7-twist, 6 Norma Dasher with exactly 100 rounds, 5/8x24 muzzle threads, polished machine finish (shot the 110 SMKs very well) $245 shipped I can also include a Benchmark 7.5-twist, Sendero contour with 1780 rounds on it. It’s 29” long and I had it on paper last week with the 110 SMKs and it still shot a cloverleaf group. It should have quite a bit of life left, or it could be sued for fire-forming. $150 shipped Take them all for $550 shipped. A buddy of mine and I have swapped numerous barrels between our Mausingfields that were manufactured over one year apart and the headspace between the two varies less than 0.002”. Additionally, he is using Lapua brass in his Norma Dasher that was cut with this same reamer with no issues. The reamer has 0.100” freebore so, with Lapua brass you’d be looking at ~0.150” freebore. I am moving on to my Impact action so I’d like to send these on to someone who can use them.
