    I've decided to have a 7mm-300Win built. I'll use it to cull whitetails & punch holes in hogs, rocks,& paper. Weight, barrel length, & portability is not going to be much of an issue. I have a 1/2 mile walk @ the most on fairly flat ground. I'd like to get y'alls input and/or experience on the perfect "stationary" rifle. I have been leaning towards R Bros to build it. It will be my first custom rifle. Any other builder/gunsmith suggestions would be helpful & appreciated. Thanks in advance.

    By "perfect", I mean action, barrel manufacturer, barrel length, contour, & stock.... It'll have a jewel trigger & NF 5.5-22x56, that I do know lol

    I just sent in my dummy rounds for throat length on a 6.5-300wm and a 7-300wm reamer. I'm going to build both and use the most accurate one for a packing mule deer rifle. I think the 7-300wm will work well for you on whitetails. I would use a rather heavy barrel if I was in your situation. Weight doesn't sound like it matters much. Using a contour with a rather long flat would allow setting the barrel back when the throat starts to go away.

    You won't go wrong with Rbros. Travis has built custom and done some semi-customs for me. He is great to work with and his rifles shoot!

    The last two I built were with a Sendero contour barrel and all 3 I have put together were Hart Barrels and a 1 in 9 twist. I have used Rem 700 actions on 2 and a Wby Mark V on the other. I am going to be starting a 4th one soon that wil be in a 1 in 8 1/2 twist with the 195 Bergers in mind. This one might have a slightly shorter barrel like 26" for ease of carry in a scabbard. All of these 7mm-300 win chamberings have shot into very tight groups with 180 Bergers even at distances past 1000 yards.

    So for you I and your type of shooting/hunting, I would go with a Rem 700 action or maybe even a custom like a Defiance. The Defiance actions are sweet!! plus they already have a nice bolt release and a M-16 extractor. For a stock I would look at a A-3 type from Mcmillan or Manners. These will be a little heavier but the weight becomes a big friend when holding on target and spotting hits. I would only use a Hart barrel and I think the 28" sendero contour will be perfect. I would also install a JP tac compensator brake and you will love shooting this rig. I know you will probably not go this far but I would just go ahead and put a 40 moa NF base on and utilize the full elevation of the NXS 5.5x22. I have seen all 3 of these rifles go past a mile on rocks and they were all very impressive. A Harris 9~13" swivel bipod is a good fit and will work from a bench, shooting house or prone on the ground. Throat them a little long for a reamer. Using the 180 VLD and the Hybrid I have found the sweet spots for these rifles were -.050", -.100" and -.115" off the lands. So the Myth of Bergers wanting to be jammed or on the lands is no longer in my mind set.

    H-1000 is the powder, and a CCI 250 or a FED 215 GM primer.

    Having owned many of larger cased 7mm made me very fond of the 7-300 win. The first one I set up now has close to 1000 rounds and the seating depth is still as we started. So I don't think we are seeing the accelerated throat burn of the larger cased 7's. These rifles will easily send a 180 over 3100 and are a perfect representation of a 7mm. Sure some will be faster, but it comes at a price of changing barrels often. I atribute some of the accuracy of this chambering to the 300 win case. After years of shooting and custom rifles I have seen few that have out preformed this case. Not to mention the superb choices of brass and bullets.

    I think you need to call Travis. I believe he is working on his own wildcat version of a 7-300. I have a 7 mag he built for me using a 26" rockcreek barrel and got up to 3029 using 180 bergers but was noticing some flat primers and very light cratering so I backed it down to 2956 and am having no issues. I am using norma vs his recommended win brass so my brass is a little softer than what he uses. Also I believe he only trues/blueprints rem 700 but Im sure would build with any custom action. I believe he has defiance built him custom actions to his specs. I would recommend him for a smith, I called him probably way to often and he always answered my questions and explained everything to me so that I understood fully.

    I shot a 700bdl 7mm RM for 20 years as a "wheatfield rifle". I thin replaced it with a 7mm RM mod 70.

    I then had a 700 custom shop 7mm STW in the nineties and have shot it for same since.

    Last year I picked up a .300 Rum so I could really stretch it out and get it there with even better BC and higher energy.

    We have a half dozen very good custom builders here at LRH not to mention Len's LR rifles so between them I'm sure you can find exactly what you need.

    Depending on where you are in Texas you might also want to give Garland a call at GGG Gunsmithing in Stephenville if you want someone more local. He builds an excellent rifle.

    With any of the above you won't go wrong.

    If you are essentially using this solely as a bench/Texas Deer blind rig, you might as well look at 12-14lbs as a finished weight, 28-30" length, 1" finished diameter at the muzzle.

    You probably want to go with a 1:9 Twist so you can take advantage of the high BC heavy bullets.

    The wildcat in the link on this post is my new 7mm Rogue. I will get some info up on here about it soon. The 7-300 works great and Broz has had alot of luck with it. I wanted to apply a theory to the 300WM case and use our throat design and see what happened. I wasn't dissapointed. I will put up a article in the rifle and bullets section.

    Looking forward to your article. We did some small changes to my last reamer too. Still no changes in shoulder angle or case taper so I can use the Redding competition 300 win dies, but did do a little throat work and leave some room for the brass to grow a little on neck length. I don't think that amounts to much, but I figured why not?

    I have sold all 3 of the rifles I put together. All 3 of the buyers are friends so I keep in touch. They all simply love their rifles and the accuracy at distance will steal your heart.

    The next I plan to keep. It will be a special build for scabbard carry and named "Wolf Whacker"

    First off, thank you all for the responses.... My next question for everyone is what are the main differences in the McMillan & Manners stocks? I know how the McMillan stocks feel.

    Wild Rose, where are you from? I live in Post about 40 miles southeast of Lubbock & have 12,000 acres 50 miles east of Post

    Travis, it looks like you have a winner with your Rogue. I believe you are building a 6.5-06 for my friend's wife. Will the Rogue see much benefit from going with a 30" barrel? How long does it usually take for you to get a rifle out to a customer?

    Broz, you could also call your scabbard gun the "wolf widowmaker". One of these days I'm gonna shoot a wolf. I guess it would help a bunch if I lived where they lived, but from what I hear, they're pretty hard to live with

    I'm at Seymour, about 50m SW of Wichita falls or about 2:25 east of you. Grew up in Farwell, spent lots of time down at White River, and I've been through Post a million times. If you're ever my way give me a shout. At worst we can spend an hour at the DQ swapping stories.

    If I can be of any help just give me a shout.

    I am building one for Curtis's wife. Its going to be a fun project and will definitely be something she will be proud to show off!

    The Rogue would benefit from a 30" barrel just like any other magnum. I would guess probably another 100fps. Right now build times are running 6-8 months out. I will have some spec builds based on our receiver that should be ready to go this winter. Give me a call if you have some thoughts or want something specific.

    WildRose, I've been to that farm equipment sale a couple times & my calling partners & I go through Seymour on our way to Archer City for the TX Coyote Calling Championship. I know quite a few folks from Archer County & the Vernon area. I'll holler @ ya next time I'm in that neck of the woods. Give me a shout if you make it to my part of the globe
