.284 win reamer

[GlennA]

I’m building a new 284 for fopen. I’m going to use the new Lapua 284 win brass with Berger 180 VLD and Hybrid match projectiles. What size reamer do the experts recommend for a good match rifle?

I did one for Norma 284 couple years ago , loaded a few inert rounds with the bullets in tended to shoot for the machinist, went with no turn neck 2 thou each side neck clearance, ended up going 230 fib which was a bit of a compromise but worked well, if your going to neck turn obviously it will have a bearing on the reamer. The vid s and the hybrid bergers have a bit of a different olive measurement too.

The new Lapua brass neck walls are measuring right at .016 so to extrapolate that out for a loaded round it would be .316 and with a recommended .004 neck clearance for long bullets, you would be looking at at no turn neck diameter of .320

What setting code do you use for this new Lapua 284 win brass with the AMP annealer?

I do not know. An AMP is not practical for my use. I anneal anything from a 20 Hornet up to 50 cal. With all the variables in between all those calibers and volumes, it is not conducive for me to utilize an AMP to my advantage.

I’m not sure what you mean exactly, do you get better practical conducive results utilising other annealing methods ?

Hi Rushty, how hot a load are you running in that new Lapua 284 win brass? Are the primer pockets holding up better than 6.5*284 necked up???

Not sure GlennA I haven’t shot them yet, can’t see the head being any different from the 6.5x, I’m expecting same life for same loads as 6.5..
