I am intersted in something that allow's for multiple rifle calibers fro the same rifle / chasis. The only 1 I've found on google is DTA which is a company that I'm not familiar with. I would like a Tactical / Precision Bolt in 308 and 300 WM. I'm assuming a barrel change would be needed due to twist rate. I would like to have 1 set of optics and the 308 with maybe an 18 barrel and the 300 WM with a 24 inch barrel. Would love to be sub .75 MOA and $3k or less for the rifle. I've looked at GAP and AI but haven't seen a rifle that had this capability. Appreciate feedback and recommendations.

Thanks
 
Good luck. I don't think you will find anything close to what you want in that price range. Would be way cheaper to buy 2 rifles and just switch the scope from one to the other.
 
The DTA is an amazing rifle. There's a sticky at the top of this very subforum with information about them.

Another "well known" swap was supposed to be the MRAD...But, we have a better chance of catching a leprechaun than we do ever getting those conversions.

I've shot a DTA and they're amazing...I'd own one but, with my state how it is, I have other priorities atm.

I've seen a few on the hide lightly used for 3k ~ Might as well buy 1 with 1 conversion and then buy the other down the line.
 
As others have said, 2 rifles. You can get identical Remington 700Ps for around $1000 each, set them up with Picatinny rails and switch your scope between them. You would need to adjust the scope zero between barrel changes anyway, so I'm not seeing a huge advantage to that system.
 
Thanks for the feedback. Is there a downside to having the conversion rifles that I'm not seeing? The DTA conversion looks great (although the whole Bullpup design is a little different - haven't had the opportunity to shoot 1). I'm not interested in a normal entry level rifle - had a Rem 700 Sendero in 300 WM and found the accuracy dissapointing. I can add to the $3k budget if needed to pull this off but don't see the AI SPR $15k +.

There are several ways to skin this cat. You can go DTA (most expensive), or get a switch barrel system using a long action receiver (lets you go 300 WM and 308), or use a short action switch barrel system using 308 and 300 WSM (that's what I would recommend). My switch hitter calibers are 308/6.5CM/223; I could easily do 300 WSM as well, which for all intents is a 300 WM in a short action.

You should get a chassis system with an AI style detachable mag system (I like the Manners mini-chassis). You need to have it inletted for whatever receiver you choose. The trick is to get one that has an integral recoil lug so you don't need to mess around with go/no-go gauges. If you can get a Surgeon, do that or go with a Bighorn or v2 Defiance.

You need to choose between having a long or short action receiver. I advise going short action because hardware is usually easier to find and a little cheaper (e.g., 300 WSM mags vs tweaking feed lips of a 300 WM magazine to feed 308). If you were to use a short action, you'll need two bolts (one with the standard .473" 308 style bolt face and one with the .585" 300 WSM style bolt face); if it was the long action, you would need a 300 WM bolt face style bolt and a 30-06 style bolt face.

Get two barrels fit up to your specs (they'll need to fit in the barrel channel of you're chassis). When you're ready to change out, all you'll need is a barrel vise and an action wrench and a little bit of nickel anti-sieze.

To get all the hardware for this, you need to be willing to spend about $4.5K (custom action w/ two bolts, two match grade chambered barrels, chassis system, two different AI style mags, tools, and everything else you need to shoot the gun). This is still less than a DTA with two calibers ready to go. You can swap out calibers in the field if you get a DTA though (I don't see the need for this except for the most extreme military applications).
 
GAP or any of the smiths could probably build you what you want on here. Just get a Rem L/A, have them do 2 bolts and barrels. And barrel vise etc like stated above and your in bidness. Your biggest problem is.....3k is unrealistic. Figure 800ish per barrel chambered etc. So your already at 1600 for the barrels alone, throw in a spare bolt is probably another 400. So your at 2k before the action or stock alone, best case is 3400 to 4000 for a L/A Rem700 setup trued up by one of the smiths on here.
 
it could be 3000 if you do your own smithing:
a savage long action
2nd bolt face
stock from stockade
DBM setup
magazine for each
prefit barrels from northland
action wrench and barrel nut wrench
scope base, rings, scope

very unlikely you would be happy with it - when you ask too much for too little, you end up with too little for too much
 
I thnk the DTA SRS A-1 may be the ticket. It looks like I can get the rifle chasis in say 300 WM for a little over $3k. Add the conversion kit down the road for 308 fpr $1500 - $2k. Just need rings and a nice optic. All in price seem's much more doable than the AI PRS. Are there othere other distributors that have better pricing than going direct through DTA? Or there GAP like wait times after ordering?

Going to do some more research on DTA but that is now where I'm tracking.
 
I have two friends that bought the Desert Tactical Bullpup style bolt action rifles. One has barrels in 338 LM, 300 WM and 308. He also bought the matching suppressor from Desert Tactical. It takes all of one minute to change calibers. It uses detachable magazines. The rifle is very accurate. I personally made a chest hit on a IPSC style silhouette target at a 1,000 yards from a bench using the 338 w/suppressor on the first shot. The scope was already dialed in for that range and the wind.

It is a pricey rifle though. These guys made a quantity purchase of at least two rifles and they still cost around 6.5K each, and that was two years ago.

This is largely what I want to do down the road when I upgrade from my beginner rifle.
 
I would say buy the desired long action (2 bolts for the different bolt faces), and then buy 2 barrels, have them put on and then go buy a barrel vise and action wrench, go/no-go gauges and call it a day. From there put the rest together. You might be able to do it for a little bit over 3k.
Action (L/A): ~1000-$
Barrel: ~300$ x 2 (Check Bugholes)
Barrel install: Chamber ~250$ x 2

Maybe look into a chassis system that already has a DBM. There are a ton out there.

That'll leave you around 1000$ to get a stock/chassis, trigger and whatever else you need. That should be a .5 or likely better rifle on a custom action. Throw your scope on top and find known dopes and get-r-done. Best of luck.

I also believe DTA is the ticket but I just wanted to make sure you are clear....the chassis for a little over $3k (as you stated below) is just that ONLY the chassis and NOT a complete rifle whether you go 300WinMag or 308Win. You need to add that after the fact. Hide vendors can save you some coin....so talk to them about getting one ordered.

If you are in the price range of $5K for the rifle alone, why not look at two rifles?

Stiller action - $950
Barrel - $330
Manners stock with mini-Chassis - $1100
Trigger - $100
Labor - $500??

So $3K per rifle. $6K you have two complete rifles. One breaks, you have the other one to shoot.

I am sort of doing this. Built up my Rem 700 in .308. Now planning a second rifle, virtually the same setup, in .300 WM.
 
The only two rifles I know of that do that are the AI PSR and the DTA. The DTA will run you about $7K with both conversions and the AI PSR will run you about $16K. Both out of your price range. For $3K your best bet is going to be just buying two factory grade rifles. If .75MOA is all you want a R700 will do that and then some and you can have two rifles for about $2K.
 
I would say hands down the DTA is the way to go. It's as accurate as any custom bolt, you can get barrels and bolts for everything from .243 to .338 Lapua, conversion swaps take very little time, you don't need a special wrench or a vise. If you keep an eye on the for sale section you can usually find pretty good deals on a chassis and conversion kits. I've bought two used barrels and both have shot excellent. Also, POI between conversion kits are very repeatable, you can pretty much write down the clicks it takes between two barrels and just go with that. I've never been off more than one or two clicks from swap to swap.
 
30-06 handloads. you can have a .300 wsm or a .308 in one rifle. Wow.

+1. Not only that, but there's plenty of factory ammo available when you need it, tons of reloading gouge, large selection of bullets, powder and brass to choose from, and you have money left over to get a descent optic.
