6.5- 7 PRC (necked down, not up)

[Coercionist]

Ive seen a good bit of support for the 6.5 prc case necked up to 7mm and that seems like a great case for a heavy target rifle in a windy day. What I am looking to due is take the long action 7 prc and neck it down to 6.5mm for a blisteringly fast 6.5 and then sling the heavy 153 atips. Have any of you tried this yet? Not sure of what to expect with velocity but I will have this on a 30" barrel so I am hoping for 3200 fps with the 153 atip/156 eol. An alternative for this could be the 6.5-300 wsm with the new lapua brass. I haven't seen much at all for either of these potential wildcats so I'd you have any experience relating to these or of the sort I would appreciate some insight.

Here's some info - but maybe you've already seen it?

6.5-7mm prc

Anyone else considered wildcating the 7mm PRC? I have a reamer on order throated for the 156 bergers. A dummy round beside a 6.5 PRC is pictured

Theres some good info in there, kinda showes that others think 3250 with a 153/156 is within possibility. Also wondering about a 99gr hammer hunter to chase the speed itch. Not sure on velocity on it though, maybe 3850?

Looking to take elk so I would rather have a 156gr, Im wanting also wanting to use a 99gr solid to chase the speed demon. I respect the insanity though

I would think you could get close to those numbers anyway. In 6 PRC, I could push a 109 hybrid about 3400 without even using N570/N565/RL26, etc. The 7 PRC has a fair amount more volume.

Check out the 6.7 Powerstroke

6.5-300Wby will push a 156 @ 3300+
26 Nosler Will push a 156 @ 3300
.264WM will push a 156 @ 3200

I made a hotrod 6.5 by necking down the .338RUM. 140 Nosler at 3,429 feet per second.
