Best 6.5prc brass to reduce clickers

[SDHNTR]

ADG or Lapua or Peterson?

Used ADG (on old lot from 3 ish years ago, maybe it’s gotten better?) and get clickers in the third firing. Is Lapua or Petersen any better?

FWIW, I tried a Cortina mandrel die without any success. It doesn’t size the base down any more than my Redding Type S. and I’m not getting this chamber reamed out. I have no good gunsmiths near me and the gun is super accurate. I don’t want to mess with it and will just buy new brass.

Lapua is the toughest of the bunch. That’ll be your best bet. But it isn’t a brass issue as much as a chamber issue. If you’re not planning to open the chamber don’t expect any different results from the Lapua brass.

Lapua is not the toughest of the bunch, ADG is. Adg needs room in the chamber to expand and be sized tho, lapua needs this too. I have a suspicion that Peterson makes Lapuas prc cases, as they have performed the same. Which is not the same in br, creed, or x47 cases, usually lapua smoke Peterson, just like it does in the 300/338 Norma line.

You need to open the chamber up with aw2 reamer. Brass choice isn't really gonna matter. Tightest sizing dies will help, so will backing off the pressure of your reloads.

Yeah, I know opening the back of the chamber is the solution, but for now, I’m just gonna buy new brass.

The tightest dies I have found for the 65prc is the Bullet Central Micron, just behind that is the RCBS matchmaster. RCBS is much more affordable, and does just as good a job. I battled this same issue prior to getting my chambers reamed out. 2950 with H1000/140s from 24" barrels was where I landed. Had I not hot rodded the piss out of the brass with RL26 over 3100fps in the beginning, I probably could have run it a bit higher.

I’m running 3060-3100ish with a 127 LRX. Warm, but not super hot.

Rent the reamer and spend the hour to fix it right and be done with it

I have Lapua brass and after 3 firings the clickers arrived. Moderate load at about 2850 w/156 eol.

Gunsmith had reamer and took care of it for $75. Well worth the time to get that chamber right.

 

[bmart2622]

Cant even buy new brass for $75!!!

Believe me, if I had even an only half drunk and half competent gunsmith near me I would. And shipping has just become too much of a headache.

I also have a 7SAUM and the clickers arrived after 3 firing with ADG brass. Slightly annoying, but I can live with them. From what I've read, they are not going to hurt anything drastically.

Do it yourself. The reamer will dust off the rear of the chamber before the flutes have a chance to cut any other part of it.

I’m fairly confident with most basic gunsmith tasks. Done several bedding and trigger jobs and a few prefit builds, but messing with the chamber machining is uncharted territory. That said, it doesn’t scare me. Is there a good you tube vid showing the process? I understand what needs to be done but visuals always help.

Do it yourself, $80 for the reamer shipped to you and an hour of your time then you can move on to something else to complain about

6.5 PRC Chamber Fix Thread

Fellas, I know there are a few of us on here who either already have the JGS reamer or are waiting for it to fix the chamber issue in the 6.5 PRC, and I'm sure there are others who are watching to see if it resolves the issue before they order it themselves. With that in mind I figured I would...

PRC SAAMI Chamber Issue - The JGS AW2 (Alex Wheeler) Finish Reamer Fix

Since I was taking my 300 PRC apart today I thought I would do a step by step, with pics, of how I use the JGS AW2 Reamer on a SAAMI chamber. The chamber on my rifle is already an AW2 chamber but this should help those with SAAMI chambers. This is the reamer. Thanks to Alex Wheeler for making...

I did mine, a guy on here had an AW2 reamer and let me rent it from him for cheap. Took me 20 minutes following the instructions on LRO.

Good pics. I’d really prefer not to have to remove the barrel and just clamp in a soft jaw vice. How hard is this to do with action in place? Assume I’d need an extension of some sort. Or handle? Is there any concern for reaming concentricity out of whack when doing this by hand?

A long 3/8 socket extension extension and a cordless drill run slow and you can do it without pulling the barrel

The guy who rents them out on LRH has everything you need to do it with the barrel on

How do you keep the reamer perfectly true/concentric to Center of bore? Seems if turning by hand it would be really easy to put too much pressure on one side and cut it out of round. How do you prevent that?

Still wish I could find a video.
