6mm-06 / 243-06 / 240 Gib


Registered Users do not see the above ad.


I would appreciate any info anyone can supply on these.
Which one would probably shoot the fastest using a 60gr bullet? Also the 100gr bullet?
Where to find dies and have reamers made.

Any thing else you might think of like tricks and tips from your experiences.

Michael,
I don't have any of these calibers, but I have some published information on them. The 240 Gibbs will have the highest case capacity of the three since the shoulder is actually moved forward to increase case body length. The .243-06 and 6mm-06 appear to be the same cartridge but I only have information one one of them, I would be making a guess to say the only difference, if there is one, would be the angle of the shoulder.

Of the load data I have, and can find, none of these cartridges produces enough extra velocity, less than 100fps, over the existing 6mm Rem (and AI) version or the .243 WSSM in the published loads. The cartridge would be very overbore and terribly inefficient from my point of view. If you want to extract the velocity, you will need a long barrelled rifle (28+" barrel) to see any meaningful increase from the data I've seen. If you're set on one of the cartridges, the 6mm/284 will be easier to find data/dies/chamber reamer for and have about the same case capacity as the '06 casing.

If you want this in a standard size rifle I don't think you'll see any gain, over 100fps, over commercially available cartridges, or the simple 6mm Remington Ackley Improved cartridge.
A 6mm Remington will push a 55/60gr bullet in excess of 4100fps in a 26" barrel. 3100+ with a 95/100gr bullet is no problem either.

What kind of rifle do you want to build? Hunting, varmint, etc? I would let that guide my decision. You can make what ever you want, but I'd make sure you're going to get some results for your money.

.240 Weatherby is right in there with the rounds that Steven mentioned.

They'll all be rough on barrels.

Another couple of cartridges in the same ballpark would be the 240 Howell (designed by Dr. Ken Howell) and the 240 Hawk (designed by Fred Zeglin).

Dr. Howell has a book out right now about designing custom cartridges, though I can't remember the name of it right now. You might be able to contact him directly at http://www.24hourcampfire.com/

Fred Zeglin is a custom rifle builder and owns Z-Hat custom. His website is http://www.z-hat.com/HawkCartridges.htm

6mm/06 dies for sale

I just happen to have a set of RCBS 6mm/06 dies for sale, complete with the forming die to make them out of 30-06 brass. I bought them new from Huntington several years ago, and loaded only a few rounds. As far as I know, they are still like new. (I have not opened the box for a long time) If anyone is interested in them I would sell them for considerably less they cost new from Huntingtons, as I no longer have a 6mm/06.

Hi,
I just looked up the price on Huntington's website. The loading dies are 119.95 and the forming die is 22.95, for a total of 142.90. I would take $70, which is less than half of retail, and, I'll include USPS Priority Mail shipping.

Regards,
Neal

try 75 Gr sierra BTHP with 45 Gr Varget (Cousin to 4064). fOR DIES TRY NECK SIZER 243. REAMERS CAN BE RENTED BUT WHY BOTHER WHEN YOU CAN BUY THE BARREL ON MIDSOUTH OR MIDWAY COMPLETE WITH STOCK FOR UNDER $200 AND IT SHOOTS GREAT. HOPE THIS HELPS.

Hi, Marty - and, WELCOME to the board! Be sure to stick around and join us in the discussions here on the many forums.

Just completed a 6mm-284 on a Eddystone P17 action. Have fired just at 400 rounds through it and must say, this is one accurate rifle with the heavier for caliber bullets!

Have a bore scope and have been watching for the dreaded "high velocity .243 bore wash/wear burnout". So far, all that has occurred has been some good lapping of the bore and no signs of extreme throat wearing or wash.

Your 6mm-06 should be comparable to the 6mm-284 as far as velocity and wear.

One thing I do is use the slower burn rate powders and only standard primers - not mag primers. Had the 'smith give me a little more leade than normal so I could seat the longer, heavier bullets out farther and not crowd the case capacity. This may account for the minimal throat erosion so far.

Thumbs up

Thanks for the welcome and the reply. I went w/ the slower twist for lighter bullets only. Do you suppose this may make a diff.?? Also I am not sure how the primers figure in?? I did plan on IMR 4831 w/ fed mag pri. If this seems wrong LMK... I suspect that it will take all of a year plus for me to get 200 rounds down range w/ any one gun!! I like to spread the wealth so to speak ... probably why my scores are not what some can do... thanks again for the response.... Marty

IMR 4831 is a fine powder - a little faster than the H4831 and the Hodgdon 4831SC is temp insensitive. The mag primers will work with these slower powders - just that I've never found them to be of more benefit over the standard primers, other than when using really slow burners like IMR 7828, RL-25, VVN165, etc.

In the twist department, mine has 1:10 and does fine with 85 to 105 grainers. My preference is the 100 and 105 gr bullets, as it will be used for up to deer sized game, not small varmits.
