Hi Magnus,
I found your website as I`m looking for a load with VV N105.
I got from H&N a data: Starline case, 10.2 – 11.0 grs, 40.3 mm. small pistol primer and a nice crimp.
I have a Marlin 1894 Carbine, 357 mag with a barrel length of 18.5 inch too.
What makes me wonder is your COL of 41.5 mm.
Most user of Marlins mention that a COL of 1.590 inch is the maximum. That´s about 40.4 mm.
My case carrier likes ammo with a COL of 40.3 mm.
Do you have no problems in cycling?
Best regards,
Willi from Austria
Hi Willi, this is the longest COAL I can get my Marlin to reliable cycle. And it gives me a few cubic millimeters more for powder 🙂
