287 Bushing

 

[mattj]

I don't use a bushing die, but the neck of my sizer is honed to .292

 

[Paulyr450]

I also use a .291 bushing. But if its a gas gun im not sure.

My loaded 260 lapua brass with 130 vld measure .294", so I'm using a .292" bushing.

 

[TimK]

I use 0.293".

 

[Graycliff]

.292" w/ 139gr. Scenars

 

[DeSilva]

13.5 thou neck wall thickness running Berger 140 Hybrids i use 288 which gives me 2 thou dimensional bullet grip

.289 for me. You are just going to have to measure a loaded round or neck thickness. It’s also good to have a smaller bushing after a few reloads the neck can get thinner.

 

[Jaxdialation]

.293 with 142SMKs

Is this a bolt gun or semi? Do you know your dimensions? Take a empty case and seat the bullet of your choice, measure the neck and subtract .002" for a bolt gun, for a semi subtract .003". I use Lapua 260 brass and use 139gr Scenars, loaded is .295" so I use .293" bushings in my bolt guns for a .002" neck tension. This also depends on what size (neck) your reamer was. I had my reamer made with a .298" neck for Lapua brass because the necks are .015". If you don't fire a couple of rounds and measure the neck on the fired case that will be your chamber size, you know what you loaded them to and you need .003" clearance from loaded to a fired case for tactical use, some BR shooters go as small as .0015" clearance and as low as .001" neck tension, but I wouldn't do this for tactical purposes cause unchambering a live round you could have a action full of powder.

I use a .292 bushing, Redding neck size only die. I am loading for an AIAE with an AINA Bartlein barrel. Works great!
