Is it necessary to chamfer the casing if the bullet is a boat tail?

It's necessary to chamfer if you've trimmed, but I've always used a light chamfer just to ensure no shaving during seating.

IMO, you should chamfer after you trim. Even for boat tails. Unless you use a flare die, like a Lyman M die.

But between trimmings, no. Not with boat tails. Might be very helpful to do a light chamfer for some flat based bullets, though.

I think originally chamfer tools were made solely to remove any burrs that might have been created during trimming. For the most part that is still true today. But some of the newer high-dollar bullets like some from Berger have an extended boattail design, sometime called VLD (very low drag) bullets. You can buy special chamfer tools that are specifically made to put a long gradual chamfer on the inner neck wall so that these expensive little babies don't get bunged up during seating. If I was loading these fancy bullets that can cost upwards of $1+ each into brass that hasn't been chamfered, I'd use the tool whether I had just trimmed or not.

And point of order. This is not aimed at the OP because I've seen a sudden surge in this at every gun forum since so many shooters are getting into reloading. A CASING is what you stuff sausage into. A CASE is what you stuff gunpowder into. That is all.:)

Thanks for the info.

And thanks to OldTex, no offense taken, I stand corrected.

My pet peeves include many news reporters talking about high capacity clips, rather than magazines, and just showing their ignorance.

And on TV, guns that don't show recoil. semi autos that don't lock back when empty and continue to go click, click, click. Geez Hollywood, get a clue.

And on Alaska State Troopers, I saw one trooper disarm someone, rack the slide and then drop the magazine. He should know better.

I use a VLD chamfer tool. It's 22 as opposed to the common 45 chamfer. Lyman, RCBS and K&M now make them.

I always have. Is it needed? Perhaps not. But I still always have done so.

Chamfer everything, makes all bullets, flat bottomed, and boat tailed go in sooooooooo much smoother.

Chamfer and deburring is a necessary point to reloading.

I agree with 45lcshooter, a little chamfer makes every bullet easier to seat. It only takes 2-3 seconds per, so I do it on every case every time, whether it was trimmed or not.
