New Special Project, Opinions wanted

Ok...i'm starting a new rifle project-series for Viersco Mfg, I want the shooters here to have some input. Its been on the drawing board for some time now and its time to get to it. I'm not going into the intricate details until its completed, i will post pics and results at that time. I will say this, it will be a takedown type rifle.

What caliber and bullet should i go with? It has to fit into a 308 magazine. I'm thinking 6mm cal or larger. The rifle will weigh in the 10-12# range, med weight barrel, 26" is the longest i want for this build. Purpose, long range targets, varmints...1000yd max range. Bullet and twist rate?

This should be interesting...

Thanks for any input.

Dave

6.5X284 or if your wanting a wildcat cartridge go with the 6.5X7MM WSM. Just my thoughts on what works at 1000 yds on varmints and the action length. [img]/ubbthreads/images/graemlins/crazy.gif[/img]

Thanks for your input BillR. I will put these on the list for consideration.

I should of mentioned the overall length can't exceed 2.820"
A special short throat reamer might be needed to achieve this seating length, depending on the bullet.

BD,

What size bolt face do you want. Sticking to a 308 bolt head gives you lots of versatility.

6.5x47 lapua or 6-6.5x47 Lapua seem to be hot at the moment. If that fire fades you could look to 260 Rem (assuming Black Hills continues production of match grade 260) 7-08 and of course 308 Win.

In the 6mm or 6.5mm cals look at 1 in 8" twist to keep the heavier pills stable.

You might add more versatility by offering a WSM replacement bolt - main potential problem is the mag may be too short for the longer VLD type boolets to work.

David.

Ditch the magaqzine and go with a single shot. If a person misses the first shot they need to stop and think a while anyway. For target and varmint shooting you haven't lost anything.

I would think a single shot would be easier to make accurate in a take down rifle. Of course your only two customers would be me and Roy. Everybody else likes a high cyclic rate of fire.

Yeah, what buffalobob said and,
What's wrong w/a 260?
But ya just gotta give consideration to something in 6.5 such as x284.

Sounds like an interesting project. Looking forward to your posts.

Re: New Special Project, Opinions wanted

Ok the plot thickens...a single shot version is also in the works...it would simplify all things. With the single shot any caliber and any bullet seating can be delt with. Personally i might build a 338 Lapua, but that is another thought.

We are not limited to a std bolt face, short mags have been in the back of my mind.

This protype rifle will have some tactical applications, hence the magazine. I am looking into some other magazine options that may make it possible to use a longer cartridge or long bullet configuration.

More cartrige info has been added to my list.


Thanks

Dave
