With the info provided by all you good folks my 6 Super project is starting to firm up.

Winchester .243 brass, have 300 low-usage cases from a previous rifle. No-turn necks with a light skimming to take off the high spot. Trim and sort by weight.

Reamer as per Kiff print # 9857 keeping the .274 neck and 1.5 degree angle on the throat. Freebore changed to .075.

Have a number of 6mm bushings for my 6AI. This week I hope to send to 6mmAR for the Redding F/L bushing die. Once received I want a good look at a resized 6 Super case before ordering the reamer and headspace gauge from PT&G.

ar1957, PT&G sent me print # 9857 which shows a .274 neck as you state. What brass are you using in your 6 Super? Turned or unturned?

9857 also shows a .131 freebore. Did you stick with this? What bullet are you using and how is it seated?

Thanks
Bill

If you are wanting info on bullet OAL's with the #9857 reamer with the .131" free bore, take the OAL's of the JGS 6mm Super LR reamer (the one with the .120" free bore) that are posted on my website and subtract about .020" from them, and that approximately represents the OAL's I get (hitting the lands) with the PT&G #9857 reamer I have with the .131" free bore.

For whatever reason the PT&G reamers I have for this cartridge (two of them) seem to run shorter in the throat (by about .015" to .025", depending on the reamer) than the JGS and Henricksen reamers I have for the cartridge (five of them total) and that is why I made the statement I did earlier in my first posting on this thread cautioning about the variance in reamer makers and differing OAL's. This variance may be important if you are planning to meet certain OAL's or if you are wanting to do something like keep the bearing surface of the bullet back close to the neck/shoulder junction of the case, but not so it sits back in the case (with my point being that you may need to deal with this issue when you have your reamer made up).

Be aware Lapua, Norma and Nosler Custom brass (243 Win) all have shoulder metal considerably thicker than the neck metal, and if you use them to make the 6mm Super LR you will have to neck turn because when you re-form the brass you will get a big donut a the junction of the neck and shoulder of the case - that's why I typically use Winchester or Remington brand .243 Win brass for the 6mm Super LR (although I have also used re-formed then neck turned Lapua and Nosler Custom brass).

Robert, 10-4 on the freebore situation with different makes of reamers.

Pretty well all the F Class and TR guys shooting on the Army ranges here in Ontario use MacLennon as their barrel maker. He has a 6mm throating reamer that he used on my 6AI so that the bearing surface of the 107 SMKs are above the donut at the bottom of the case neck.

My plan is to get the 6 Super Sinclair F/L bushing die from you first, make up a dummy case with the 107 SMK seated where I want it and have a good look at the cartridge. Then order the PT&G reamer probably with .075 freebore. Send the dummy round to Rob along with the reamer and headspace gauge when he gives the go-ahead. If after reaming the chamber, the throat comes up short then Rob will use the throating reamer to match the dummy case. Will have to negotiate with him the jump to the lands if any. He has his own ideas on this subject.

Have to catch Rob in a batch of 6mm barrels to have prompt delivery. If he is doing a batch of .308 bores for the TR guys then just have to wait. But I am thinking of 2011 for full 6 Super usage anyway. By then my 6AI will probably be shot out. Gives me plenty of time to get everything right.

Bill, I talked with Kiff today and he said he had a much better design of reamer that he and Lonnie Hummle from Hornady put together for the Team Captain in Canada its called the 6MM HK . I am going to get one on the way. He was working with Pete his inspection forman on there new ISO program, it sounds like its a very good inspection system and very costly. I did not relize Kiff had purchased one of the other tool shops back east and he was moving it to his shop . Looks like more great things to come from Pacific Precision Grinding and Pacific Tool and Gauge. Thanks Trace

Perhaps you would identify who you really are since I see you just joined this forum and your only postings are on this thread.

No Robbert , I am no PR man. Here with a crew of Three we build rifles and classic cars. We find the pacific tooling works great and we are very good frends of Kathleen and the crew at pacific. In fact I am not good with the computer so I do not get on it very much. I spend most of the time on the lathe. I like this board and this is the first place I landed. My brother in law Frank is on here all the time. I listen to alot of folks and I should have a right to inform , dont you agree. I will call pacific they should get a kick out of this. Thanks Trace.

 

[dave kiff]

Trace I am sorry you have to come on board this way. You guys are great and do great work . Bill or anyone looking for a 6mm wildcat reamer we are here to grind what ever your needs are. I have talked with Paul and I have decided to spend more time on this board.

 

[dave kiff]

Sorry I had a call come in from remington and had to get off here. I was going to say I will be working with Paul to inform you all about reamer design by posting all our prints on site with complete history on performance ,speed and accuracy. This should be a help . If anyone has a question about anything call . My shop number is 541-826-5808 and my cell is 541-660 5724. I need no PR man I am alive and well. Thank you all Dave Kiff

Kiff Reamers

Hi Dave good to see you on here ..your name is a household word among the serious shooters/gunsmiths....It is great to hear that you are going to catalogue your reamers and make all that great info available to us who use your info for competition and hunting rifles....THANK YOU for the effort and the great work you do...Roger ((send the check to my home addy...grin))

 

[dave kiff]

Roger , I just got off the phone with Les Baer . He told me he would be our PR man for a reamer. I told him you would do it for five bucks. All fun aside I do have a new design of 243 reamer to talk with you about. Give me a call. Thanks Dave

 

[1000yardstare]

Dave, great to have you on board. I am curious about Trace`s reference to a 6mm cartridge called the 6mm HK for the "Canadian Team Captain".

Is the 6HK a totally new cartridge or a derivation of the 6SLR?

Is he referring to the Canadian F Class team that went to Bisley last summer? As a Canadian F Class shooter I am curious.

Bill

 

[dave kiff]

Hello Bill, The 6mm HK is a 33deg. shoulder design of the 6 super and the older print under other names. The idea and reamer design was not mine but Bob Pitcarins and lonnies. Call and Ill get you the print.

 

[expiper]

HI Bill ...you are on the right track with your project...Dave will help with the right dims. on the reamer ....Good luck...Roger
PS...check your PM's on here..!!!!!

Oh I think either PTG or JGS will make pefectly good reamer. I'm sure Roberts recomendation was honest from his point of view. Were trying to have a productive conversation here. The fact is Robert has affordable dies and I want a reamer that matches that die.

Dave: Start a thread on the 6HK. It's fine to compare and contrast to others. That's what this sites about.

Seems to me that Hornaday is trying to hijack a cartridge that has a chance of taking off due to some good work done by others. I'll bet they change it just enough to make it hard to form so you have to buy their brass, which sucks and may just end up killing the thing.

Just my 0.02

To All:

My original posting on this thread seems to have precipitated a bit of "battle lines" drawing that was not intended.

Let me say this: Who you go to for your reamer and tooling makes no difference to me as I have no vested interest in that aspect of things one way or another. I use who I use and like who I like, and you are free to use who you like and who you feel does the best for you - it's that simple!

If you like Dave's/PT&G's reamers - great - buy them!

The beauty of this country is we can have differences of opinions on things and still peacefully coexist.

I also like Dave (and Ashley, and Kathleen, and all his people who I have dealt with over many years) too and they are good people (I never said they were not).

I spoke to Dave today on this thread (yes - we are on good terms) and I suspect we would both concur that people may be reading more into my original posting than is there.

I am going with the 30 degree 6 Super LR as per 6mmAR. Just contacted 6mmAR for the Redding F/L bushing die. When I have set up a dummy 6 Super round I will contact PT&G for the reamer and headspace gauge as per Kiff print # 9857. That way I know that the F/L die and reamer match.

I shot with Bobby Pitcairn at the Canadian Fullbore Champs last August in Ottawa. I was only thinking of my 6AI at that time so the topic of a new 6mm never came up. Will probably see him again this August and talk over his 33 degree version of the .243.

 

[dave kiff]

Bill , I talked with Bob and he said he will get back with me on the design. I look forward to posting prints and load information on many calibers . I will try and get prints out for folks to share . Ill do what I can to get designs that people will not have to pay some large mark up for gimmick dies . Wildcats should not be priced so high it hurts. Thats why a custom reamer does not have a custom price here at Pacific tool.

 

[ar1957]

Dave , I would like you to grind resize reamers and 6 of your die blanks for both the 6mm super LR and the 6mm HK . I will make a few extra dies .If you know of anyone looking for full length dies let us know. Thanks Trace.
