Does anyone have any heavier bullet data for this little round? Would quickload be able to hypothesise on 90/95gr ballistic tips or 100gr hornady RN in a 24inch barrel with whatever powders advisable at standard 222 rem mag pressures? | ||

1894: I just responded to your post about .222 Mag brass. If you're considering a 6mm on this case, but are worried about brass availability, why not go for the 6 X 45 (6mm-.223) instead? It will give you velocities within a whisker of the 6 X 47, and you can have brass running out of your ears. Besides, if you build it on the Sako L461 action, the 47mm case will crowd you a bit for magazine space. | |||

Stonecreek, I take your point - I had initialy thought 6x45 but the factors which made me think 6x47 were:- The rifle builder has a 6x47 reamer and guages and has built 2 other rifles in it. It would be a fair amount more cash to get a rifle in 6x45 which he doesn't have. I have seen legal data for it I rather liked the longer neck to hold onto those heavier bullets and also that the 222 rem mag runs at lower pressure (I think) The plan is to build it on a remington short action which apparently has a magazine box which is long enough to take a 2.7inch COL The build spec is (at the moment) rem 700 short action blue printed and trued This will result in divorce and penury but after 4 months of thinking how superior my wooden mausers are I've decided 'if you can't beat them join them'and am venturing into both the wildcat (albeit very simple) and US style custom job all at once, now pass me that Stetson and those boots....

ScottH, Many thanks for this exhaustive data, dare I ask if you could run it with a COL of 2.7? Also is there anything to stop me theoreticaly running at 223 rem pressure? I need to theoreticaly get 2920fps with a 90gr or 3100fps with a 80gr. For actual use I plan on using a fast powder and more sensible pressures to minimise muzzle blast and hence noise. I agree QuickLoad is a tremendously powerful tool, unfortunately I only have a work PC on which I am not allowed to install any software.

1894: Now I understand. The 6 X 47 is the logical choice under the circumstances, and I don't think you'll really have any trouble finding brass for it. Your 700 action is more than long enough for the 47mm case, even with the longest bullets seated out to maximum reasonable depth. Now let me throw you for a loop: Have you considered a .25 x 47? With 87 to 100 grain bullets, this little jewel would make a honey of a light deer rifle. Velocities with a given bullet weight should run 50 to 100 FPS above the 6 x 47. Just a thought. | |||

1894: I do not know if this is of any help to you, but I shoot a 6mm X 47 in a Remington XP-100 pistol with a 15 inch barrel. I use this gun in Unlimited Anysight competition for NRA and IHMA silhouette shooting. I shoot 24.8 grains of WW 748 fired by a Remington 7 1/2 primer and use a Hornady 100 grain Spire Point. My Oehler 33 says the average velocity is 2150 fps. Not bad, I would say. R Flowers | |||

Hi 1894, The following data are estimates at 58,000 psi and 2.7" COL. It looks like you could reach your desired velocity with no problems. Quickload states the max working pressure as 58,740 psi. Whether the loads would be ok at 60-62 kpsi in that cartridge remains to be seen. I have no experience with .222 mag brass, but I would be surprised if it was weaker than .223. code:Cartridge : 6 x 47 (6-222RemMag) | ||

Stonecreek, .257 will be considered by our illustrious firearms licencing authorities to be too close to .264 (which I allready have). Thus in their eyes I would not have 'a good reason' to own both. I think the 6mm version should suffice. Thanks everyone especialy Scott H for all the help, I'll let you know how I get on. [This message has been edited by 1894 (edited 08-06-2001).] | |||
