Lee C309 in Marlin 336

[Sneakybuffalo]

Is the Lee C309 170 grn. supposed to engrave into the rifling? I haven't had a chance to slug my throat, although it seems that I don't really have one and the rifling simply starts abruptly.

Anyways, after creating a dummy round crimped in the crimping groove and inserting it into the chamber, the rifling seems to very lightly engage the bullet for the majority of the length of the nose (around 0.210").

Is this what a "bore ride" bullet is supposed to do?

I can't get a picture due to the high gloss black powder coat on the bullet.

The nose mics right at .300 at the high spots.

The C309-150-F engraves in my 30AS. I think it is pretty common.

After the powder coating what do they mike at? I've got the 160 gr mold and some other Lees that are for .309 (and others, Lyman, RCBS, that are probably not much bigger). I haven't tried powder coating yet but have read about it and was giving it serious thought because I don't think they are going to be big enough for the mg barrel. My Lee 155 2R @ .312, SPG and gc'd works great. Wanted to go from there up to 180s and see. Like to see your pics if you can get them to show up.

Having the nose of the bullet engrave when chambered is a good thing. Many "bore-ride" bullets don't ride the bore.

I have three Lee C309 moulds 113,150 and 180 all work very well in my 30-30 Handi When I powder coat mine it adds a little to much engraving and I have to "slam the door" to chamber them I'm going to do some alloy changes to see if I can find the right size. I am to the point that a nose sizer die is moving toward the top of my gotta have list. GP

I'm very new to casting and powdercoating. As in, this is my first decent batch of bullets, so your mileage may vary. I need to get a bullet sizer, but I need to slug my throats first to see what I need.

Anyway, here's some pics for your viewing pleasure.















There wasn't really any flacking except where the lead legitimately got gouged by the pliers I was using to hold the bullet at first, but you can definitely see that the coat is pretty uneven, so I need to improve my method a bit. I had too many bullets or too few BBs in my container when I shaked.
