    Lightbulb Copper Washed / Coated Bullets

    Have been using Frontier 158 grain Copper coated or washed bullets in 0.357 mag Marlin U/L (micro grooved barrel). These FP bullets have a cannelure which enables the bullet to be comfortably crimped.

    Coming to the end of my supply of Frontier bullets. There are several companies offering a similar 158 grain FP Copper washed bullet but they do not appear to have a either crimp groove or a cannelure.

    Has anyone used these bullets to load up rounds for an U/L rifle ??. Can the bullet be crimped into the case, despite there being no groove. If crimped does the crimp damage the copper coating

    I have been using LOS copper plated - and it's a thick copper plate - and a light crimp which does dig slightly into the thick copper plate. Bullets recovered from the sand show no sign of the copper being stripped or otherwise damaged in the area of the crimp. I guess it may depend on how tight you crimp and perhaps the thickness of the plating?

    Lee factory crimp die is cheap and works well without a canelure

    Seconded. I shoot a lightly-loaded 158gr hard-cast lead FN in my Ruger Super Redhawk LBR, and give it just a touch of 'squeeze'. The chronographed difference is an amazing 110 fps on average, with the 'crimped' bullet the faster of the two.
