Hey there guys anybody have any 243 or 6mm wildcats out there?
Was wondering what i could do with a 243 winchester chambering to realy make them fly.Something besides a 240 Weatherby.
Thanks for your time.

Hey Northern Hunter, You can change that 243 [I don't know what type of rifle you have] into a 243 Ackley Improved or 6 MM Rem. Ackley Improved. With my Encore and a Bullberry 24 in. heavy barrel in 6 MM Ackley Imp. really increased the velocity and is it accurate!!! Jimbo

6mm WSM?

Jeff Harp over at Huntamerica built his own Wildcat he calls the 6mm Harp. Apparently it's pretty hot. You may want to contact him for details.

6mm

I'm getting 3800fps with a 70gr out of 6mmai. That's getting pretty close to 6-284, 6-06 . Anything beyond that, is going to be Tough on barrel life. It all depends on what you want to do, range wise, and whether you're punchin paper, or animals. O

I've been a 6mm bore fan for more years than I would admit to. I wanted a cartridge with ballistics rivaling the Ackley Improved 6MM's without the feeding problems. I designed what I thought would work, had the reamer made and had a barrel chambered for it. I split the difference between the 6MM Remington and the 6MM/06. Remington's case is 57MM in length, the '06 is 63MM and mine is 60MM. I maintained the original Remington shoulder angle for ease of feeding and am delighted with the resulting cartridge.
I load the 100gr. bullet in front of 50gr. of Reloader 22 @ an average 3257fps instrumental 15 foot.
Have taken numerous deer and Pronghorns along with a half-dozen elk with it. Those 100gr Remington's seem to be the ideal bullet for big game. The sub-minute groups don't hurt either I suspect.

God Bless and good shooting!

The .243 is already overbore try going the other way, 6mm-250AI

Who needs one, 55 gr. bullet at 4000 fps and a 68 gr. bullet at 3700 fps will handle any of my varminting needs, plus be a good deer rifle with 100 gr. Partitions. I think Winchester hit the nail on the head with this cartridge, it's one of my favorites.

Frank,

I've been fortunate to stumble onto a source of retired Shilen 6PPC benchrest barrels for cheap. They have 1/15 or 1/14 twists so 75 gr. BT bullets or 80 gr. FB bullets are about the that can be accurately be fired out of the barrels. Having a couple 243s I wanted something different and didn't want ot deal with the hassle of finding 6PPC brass. So I short chamber the barrels with a 240 Weatherby reamer and use 220 Swift brass for casings. Reloading dies are made by cutting back a 240 sizing die and I use the seater die from RCBS 243 competition die set. The cartridge is about the same as the 240 Apex(?) wich was a 6mmx220 Swift w/o the need for a custom reamer or dies set.
