130 gr Accubond/ AA2700

Hi, my name is Bret Beard and I just joined the forum yesterday and just went out and shot my new Ruger M77 target model today for the first time. I Fireformed some Creedmore cases using 243 winchester and they seemed to work ok. The 140 gr Hornady shot  good as well. I am just breaking in the rifle so I cleaned it after each 3 round string. I started with a 39gr load of AA2700 to fireform the cases. when I reload them I will get back with you with the results.  I shot an initial 1/2" 3 shot group with the Hornady loading in a pretty stiff tail wind. I am glad this forum has been started. It will help us all get more familiar with this new cartridge.

Hi Bret, welcome to the forum.  I am happy to learn that .243 Winchester brass can be used.  I have Hornady 6.5 Creedmoor brass on backorder, but I can get Lapua .243 Winchester pretty much anywhere.  Do you do anything to the .243 brass before fireforming it?  Do you re-size it first with 6.5 Creedmoor dies?  Tell us more.  I am glad you found the forum and joined.

Hi Guys,  Yes I trim the brass to 6.5 length and then use the 6.5 dies to properly size it. I believe there is a little more taper on the 243 brass, so it will fill in a little when you fireform it,. I have also read that you have to watch the inside of the neck where it comes of of the shoulder for brass buildup. I have also read that you can use 7/08 brass as well.

Thanks for the information.  I did some research on ammoguide.com and got the following pictures:







It looks like the .260 Remington is also another choice.  What would be better, streching the case mouth of a .243 Winchester to .264, shrinking the 7mm-08 Remington to .264, or using the .260 Remington that is at .264 already?
