    SC4 Conceptual Thinking

    So, with the SC3 prototype nearing completion, and the SC2 design finalized, and prototype started, I got to thinking about the next "big" development for SC Rifles. The SC4 is our .338 Lapua offering. Now, I will admit that this was spurred on by a few emails asking about the development of a Lapua based rifle. So how about if I run my idea by everyone and see what kind of responses I get.

    First off, like all SC rifles, I'm trying to fill a niche market that isn't already being filled by the existing rifle makers out there. So, to start off, there are several 338 Lapua Rifles available:

    Dakota Longbow - $4500
    Sako TRG-42 - $3300
    AI PM (L115a1) - $4500 (est)
    Armalite AR-30M - $1600

    The one thing that is notable is that these are the pre-made type rifles. In otherwords, you buy one configuration, they are not custom rifles. I know there are other custom rifle builders out there that will build a .338 Lapua, but I'm not sure on their pricing.

    Now, let me present the SC4 as I see it, and the price.

    CZ550 Magnum Action
    McMillan McHale or Baker Special stock (possible other options, checking with McMillan)
    26-30" MT Rifleman Hand Lapped Barrel of #6-#8 contours
    MT Rifleman brake or JP muzzlebrake
    http://www.eabco.com/images/JP02.gif
    Glassbedded with atomized metal for strength
    Teflon or Epoxy Powder Coating

    Price - $2100

    So, feel free to comment.
    One thing I do know might be a limiting factor is the small selection of good bases for the CZ550 action. Ken Farrell does make a 20 MOA Rail adapter, but I've not seen it in person.... (thats easily changed with $100).

    The Armalite is cheaper, but I'd like to hear how people view it and wether it would be a competitor...

    Now, when commenting, please be aware that the Lapua is an odd duck and does not fit in MOST actions. It will not easily work in a remington. If you go with a single shot, you can possibly use the savage or winchester, but the bolt face diameter is also not normal, as its based on the .416 Rigby. The sako action was another possibility, but the new model 75 is not large enough.... The CZ is a good, semi affordable solution.

    Anyway, feel free to comment! Good bad or indifferent.

    Mel,
    How much would the addition of a detachable box add to the pricing. As i recall, all the rifles you mentioned with the exception of the Dakota come with a detachable box, so it might be something to think about.
    My $.02
    If you're not living on the edge, you're taking up too much room.

    Mel,

    You can check out PGW Defense Technologies. Their lower end 338 lists at just under 3kUS

    The LRT-2 Can be chambered in 338, it is all the way at the bottom.

    I can look into detachable box, but fear it'll add significant cost. But will see what I can find.

    The PGW LRT-2 looks like a nice setup. $2975 does not seem too bad either.

    I'll have to look closely at what they offer vs. what I am proposing. I'd like to get the price of the SC4 below $2000, but will need to wait to see how the prototype turns out with costs, etc. I may be able to do it

    Mel,

    I saw one of those JP brakes on a 338 win mag at the range a couple months ago. I don't know about its performance but I didnt lke the shape of it. It looks like it would get hung up on everything your trying to walk thru. I would like to see something that more matches the contour of the barrel like a Briley, Viass or KDF. I would really like to hear more feedback about a Viass brake also.

    Did I spell Viass right?

    Just my thoughts.

    OK if you are going bigger are you ever going to the 50bmg?

    What about a 30-378?

    Somewhere on the net is a guy that is making/installing the AR50 type mb's on rifles. I am sure it works well, but would be hard to drag through the woods.

    Well I'm glad to see the SC series coming along, I've got a couple thoughts about the SC4.

    The opportunity for a custom configuration is good, and the price is great. Single shot would be acceptable, but of course a repeater would be better. I don't care about detachable mags in a bolt action. Also I think the SC4 would be way nicer than the AR-30, the only competitor in price.

    I REALLY like the idea of using the Baker Special. The setup sounds good as you've desribed it, with the options and all. (I'd probably go with a #8 contour for the extra weight). A cut-out in the cheekpiece (if there is one) for removing the bolt with the cheepiece raised would be nice too.

    With scope bases being a difficult proposition, maybe you would think about upping the price of the rifle and including the base.

    It's definately a niche market, but the SC4 you described would fill it well I think. Being a Lapua ammunition dealer doesn't hurt either. .338 Lapua is punishing to shoot though, on the shoulder and the wallet. Personally, I wouldn't buy an .338 Lapua, but there are probably many that would.

    P.S. I would love to see the Baker Special as an option on an SC rifle in a standard caliber.

    Well, thats my .02

    The Armalite AR-30 is a solid rifle and well built... not to mention its not "alot" of money concidering what caliber it is... as you can see its one of the cheapest .338's out there (price wise)... its the rifle i would buy if i wanted to build up a custom .338 Lapua.

    Now... after the .338 SC4 is done (if thats what Mel chooses to do) i would like to see (and i think others might as well) either an AR-15 SPR or a M-21 / XM-25 DMR... the semi auto DMR / SPR rifles are starting to see ALOT of use over sea's... both as a spotters rifle and a snipers rifle. Both of the Snipers in my platoon and both the spotters use XM-25's and MK-12 Mod o / Mod 1 SPR's most of the time over the bolt action rifles while in urban or otherwise intermediate quarters (when the furthest you will "generally" shoot is 1-500 yards)

    The JP was just one of the possibilities. I put the link so people could see what it looks like. I am not settled on a brake yet, but it WILL have one.

    The CZ550 Action has integrated groves for mounting scope rings, but of course, there is no 20 MOA of cant, which, depending on scope, you may need to get to extreme ranges (up to 1 mile) with the Lapua. With a no cant setup, the Leupold Mark 4 16x will just about get you there... (it has 140" of elevation at 100).

    The DMR is on the drawing boards, but I have yet to find a niche that is not already filled by others. I don't just want to build another M14 based DMR... it has to be unique and be different from whats already out there, and of course, be a good deal.

    I'm also thinking of a .223 AR based system.....
