A guy I used to shoot with built one for 1k shooting. He built it on a long action so he could shoot heavy bullets. It never was very impressive, but maybe if he had stuck with it long enough he might have got it worked out. He went back to 284 Winchester, which in my opinion is the best 1k 7mm out there. Its definitely arguable the 284AI is a better windy day cartridge. The 284 needs to be built on either a long action or a single shot action. The 7 WSM is a fine 1k cartridge if built on a long action The 7 SAUM is not shabby at 1k either.I was thinking of suitable carrtridges for some informal long range shooting (1,000 yards +), and a smattering of some 600 yard F Open matches.
It got me curious as to necking the 25 WSSM (largest caliber made in WSSM) to 7mm.
Thoughts?
