Boyer 3 Reamer Comments for 6mm PPC

Question - There appears to be a trend towards minimum clearance at the base of a cartridge case but still allowing for sufficient expansion so that the brass can be re-sized. The current Boyer III drawings from Dave Kiff is showing .4409 at the base and .4398 at the .125 line for the 6mm PPC. Is this too tight
to allow easy resizing etc or is this the current thinking? The 1.500 case length for some reason appears to be popular. My worry is this doesn't allow for much case expansion, but maybe there are beneficial reasons for this short case length? The Boyer III drawings that I have show a 263 neck. Is there any benefits to the 263 neck or is the 262 neck still the most popular.

Answer - The reason that many of us use a minimum base diameter reamer is two fold. First, it allows very little expansion at the web, which seems to allow the shooter to shooter in the upper load window with a minimum amount of abuse on the brass. The less you work it, the longer it last.
Second, this also aids in keeping the primer pockets tight, as very little metal movement occurs.
But, as you noted, if you make it a little too tight, extraction problems will occur, usually in the primary extraction phase.
I worked with Dave Kiff on my reamers, and I feel like I have about the right size at the .200 down mark. We started with a Boyer 3, then made the .200 down from the bolt face .4402. The reamer at the bolt face is .4423. I have had very good success with these dimensions. I also took the overall length to 1.515, for the reason you noted.
Also, I went to a .269 neck. If this is your first PPC, and are not locked into a lot of equipment built around a thinner neck, then I would highly recommend the .269 neck. Why? One reason. Ease of making cases. In my opinion, there is simply no reason to turn all of that brass from the neck. The .269 is just right. My last effort on this reamer is a "zero" throat design. It is looking promising, and I just might commit to it for the coming season. Dave Kiff has all of these prints on file - by Jackie Schmidt _________________________________________________________________________

Jim Carstensen - Recommends minimum of .4405 at the .200 mark.

Jackie Schmidt – Using .4415 at the scratch line (which more or less represents the bolt face) and .4400 at the .200 mark (.0005 larger than the case). The end of the chamber where the forend of the extractor grooves measure about .4403 so the Reamer cuts about .0008 over the corresponding spot on the 220 Russian. Ask for Jackie's 6PPC Reamer with the .262 neck (Modified Boyer 111).

Boyer III - The Dave Kiff Reamer # 1045 was built for bullets on the .790 jacket length

Aaron in TN - The JGS #1045 is a really good semi-standard .262 neck reamer, and is usually an off the shelf item from them. It DOES NOT work well with some of the super sharp ogive bullets now on the market. (has .060 frebore) If you stay with the 7-8 ogive bullets, it's hard to beat. It suposedly is Farris Pendell's original PPC chamber.

Roger L Haney - I got 3 of the JGS reamers and all are the 1045 with 2 exceptions, the standard 1045 has a .060 throat which is good for 7-9 ogive bullets, I had 2 more ground to a .035 leade and a .050 leade and all with .262 necks. Jackie's version is fine and it works for him. I don't want a base bigger than .440 and prefer a .439. All the 1045's I have are with a 30 min.1.05 deg throat.
I have never had a problem with JGS reamers. All have been to specs and I have about 30 JGS reamers.

James in LA - I bought the Boyer #3, but soon found that it did not suit my dies, etc. I found it too tight at the web and too short (1.500). I gave it to Speedy and got a more conventional Hendriksen reamer. There is nothing wrong with the Boyer #3, but one has to have a FL die made for it and he has to watch his case length closely

Jerry Dailey - I use a .263 Boyer reamer from Dave Kiff and Mickey Coleman does my chambering. All my barrels are chambered alike. I called Harrells and told him what reamer I used and he knew what die to send me. I also use a small base Redding "S" die for one barrel because it requires a little more shoulder bump than what my Harrells is set at. It sizes the web just right but oversizes (slightly) the area where the shoulder tapers.. I am very happy with my set up. Keep your brass trimmed to 1.485 to 1.490 as James mentioned. Over length can cause blown primers.

Jerry Sharrett - The "standard" 6 PPC reamers were the JGS 1045 (1.525 length X .262 neck) and the Boyer #3 (PTG 1.500" length X .263 neck). Most shooters now are probably going with a 1.515 length since you don't have to trim cases before fire forming with the 1.500, or you don't end up with the longer brass-to-chamber end with the 1.525. As far as neck diameter the jury is probably still out, larger neck coming more in vogue (say .266 to .269).

HovisKM - Dwight said it was a JGS1045 spec reamer with a .263nk. He didn't say if it had an actual print name or not. He said there was really nothing to improved upon the JGS1045 print and that is what he chambers. You can buy a Redding SB 6ppc die and a Wilson 6ppc seater and the match will be very near perfect.

Reamer (Dave Kiff) - I grind reamers for Tony and many others, yes Tony has a reamer named the Boyer III he also calls it Pure Magic. Tony also has a Boyer I and a Boyer II . These reamers all have the same body with diff. freebores . Tony said the III or Pure Magic is the best for his load. Tony has sent many shooters to me asking for the Boyer III by name. 

Roger L Haney - I got 3 of the JGS reamers and all are the 1045 with 2 exceptions, the standard 1045 has a .060 throat which is good for 7-9 ogive bullets, I had 2 more ground to a .035 leade and a .050 leade and all with .262 necks. Jackie's version is fine and it works for him. I don't want a base bigger than .440 and prefer a .439, all the 1045's I have are with a 30min .1.05 deg throat. My 3 reamers are 1.505 chambers and I trim to 1.490 and shoot a long time or until I get tired of looking at the brass. Two ways to look at it, all the brass turned off the neck, you don't need all that brass on the neck or off, the time and effort saved from neck turning is good but a turned neck removes any possibility of a few bad necks.

Notes

* Lapua Brass .4395 at the extractor grove.

* Cases grow at the web with more firings.

* Add minimum of .0004 to body diameter to prevent ‘click’ problem when extracting.
