    extended floorplates for various actions

    We were getting ready for spring, but had a wet snow last week, so took the day and thought to make a universal floorplate design with programmable depth and either flat bottom or signature elliptical:) ParkWest standard floorplate up next unless Sprng arrives.... CZ550 Magnum, std depth...

    416 Taylor brasses vs specs

    guy I sold my Lott to is also into the Taylor and had issue with Norma brass in his chamber, so motivated me to make up this table. My understanding from Redding there is a slightly improved version, 30 vs 25 deg shoulder and a bit long to the shoulder, aka Manson, and the std Asquare/Saami. My...

    416 Taylor and B&C

    CZ550 medium action in a B&C cz550 std stock. Great inlet fit, custom barrel profile with stouter barrel after the forearm. Anyhow, designed a gripcap to fit their magnum Stock thinking the medium was the same shape, Nope. That is quite interesting the stocks are a bit different in the grip...

    I heard they were at DSC this year and looks like they got a website up. Sounds like some good rifles, stock blanks and components coming up but I will be patient. Never enough gun companies.... Drake & Hudson Co

    help me choose what blank goes where?

    Bought this pretty pair of Bastone (Cecil Fredi, cut from the same tree) a couple of years ago to build a set of rifles, 375 H&H and 404 Jeffery, and thanks to our good friends at Raven Rocks with the supply of 404J brass, I am getting ready to send off but.. for the life of me, cannot decide:(...

    express sights V-groove, what say you

    Finishing up design for multi-leaf express sights and thought to get the input from the aficionados here. For a large 2.5mm bead, 3 obvious options with the groove at 1x, 2x, 3x reflected bead diameter. In all case, the field of view is large at 50yards. Most of my current rifles somewhere in...

    Express Sights: 1folding or 5, Oh No...

    For my Iron Sighted Friends:) I was talking with the founders of the Drake & Hudson Co (coming this year) about express sights and folding leaves. This got me thinking about them from a practical standpoint (being a retired engineer) and being winter and all, thought to put into pictures their...

    318 Wesley Richards vs 338-06 ballistics, Apples to Apples

    I fit QL to Hodgdon data for the 338-06 and used that for the WR. Set the WR to its max. rated pressure and set the 338-06 to the same. Woodleigh 250gn bullets for both, 24" barrel. The BC for the 338 was lower than for the 318, why the velocity drops of quicker. Then, because 338-06 is...

    An African 2 rifle battery for sale, 375H&H and 458 Lott Ruger RSM, ANIB

    I bought these about 15 years ago, probably from Cabelas, not sure if NIB, so lisiting ANIB. For some reason, I never got around to shooting or reloading them, so off they go! I think most folks here are familiar with the RSMs, so will not belabor them. Boxes a bit beat up, moved around with me...

    .474 groove 470 Capstick barrels

    Will be ordering a couple of barrel blanks that have the .474 groove to match most, if not all, of the available bullets, rather than be undersized with the .475 barrels out there, which is ok, but just the engineer in me:) Will be to this dual taper contour that fits cz550 magnum stock barrel...

    home libraries, please show

    The thread about Bell on Kindle got me thinking... My wife and I have always loved books but in our younger years, they were always stuffed hither and thither:) Fortunately, in our mountain home, we finally have a "library". Still have 20 boxes of books up in the hay loft:( I will start...

    333 Jeffery vs 318 Wesley Richards

    I was in the library this morning reading John Taylor regarding these classic cartrridges and guess what, the 318 WR wins with 8 pages vs the 333J with only 6 pages:)

    Going to the gunsmith this month:) My vision of old school with maybe to nice of a wood and modern update with the peep sight. Is this Turkish blank "to much" for that time? Thanks Steve and the wood photo from the guy

    DGR (bolt) balance point from the trigger

    designing up added buttstock weight to add weight and to shift the balance point to app. 5" forward of the trigger. Looking at shotguns, Mr. Harry Potter (i know...) and the photo, all come in around this distance. I should note this is about 1.5" more than half the spacing between my hands on...

    All the 416 Taylor threads got me worked up and my brain moving. thinking of cost effective rifle (well, maybe not:) but with some upgrades.

    old school Rigby, Wesley Richards barrel

    Saw this pattern on some old Rigby's and WR and thought might be fitting on 9.3x62 Mayfair square bridge action. To basic, to tall, to clunky,not worth the effort...? thanks Steve

    CZ Upgrades are back with Matrix Gunsmithing

    I see the comments about CZ upgrades, so thought to pass along some recent information for the folks here. Tim finally got his custom parts endeavour tooled up and has re-started his CZ upgrade offerings. He hated to pause the gunsmithing but he just had no time on the machining end and was not...

    bullet weight and ballistic coefficient and 400 yards

    for the same bullet form factor and given constant pressure, how does the bullet weight and muzzle velocity affect the drop and velocity at 400yds. For Sierra gameking bullets in 30-06 at constant 60kpsi pressure (QL and QT), the chart below shows the results: Note the muzzle velocity range...

    Quickload results using 30-06 data fit

    A gentleman in another thread asked about load data for the 470 Empire (tweeked my interest, so looked in that) and this got me thinking about my method of using Quickload for cartridges with no load data or no pressure data (such as Weatherby cartridges). Hartmut Broemel (the developer of...

    Commissioning my version of German octagon barrel

    Hope to have for Christmas present. Looked at a couple of old school rifles and came up with this blended design pleasing to the eye but functional. The rear sight is also custom based upon Mark's "mini" express (NECG) in that it is made 0.100" narrower to better fit the quarter rib. Steve

    If you were to buy a semi-custom African hunting rifle…

    Wanting to get a sense of where the folks might be on this. Since there are a number of CZ550 magnum actions floating around, what would be the cartridge of choice? My thinking is 416 Rigby. Nicely fits that large action, components available, lots of history in Africa. 375 HH or 416 Remington...

    Custom barrel length for dangerous game bolt action rifles

    for a custom barrel, what lengths are folks specifying? when designing barrels, i normally use Saami spec. (bolt face to muzzle) but i think most hunters use what i call "handling length" which is from the front of the action ring to end of the muzzle. These would be on Model 70, CZ550 magnum...

    a pair of rifles for Alaska, I know...

    this is an African forum but thought folks might appreciate this pair. My gunsmith made these for himself and being a nice guy, sold them to me. They both have his integral barrels (which I am a fanatic on) and pre-64 actions. Top is 375H&H and the bottom is 7mm RemMag. As a pair, I normally...

    A-square 416 Rigby Purchased In 1985

    I order this rifle from A-square in 1985 and has been in storage since then, but moved states a few times. Wanted a Rigby and at the time, seemed the only available option.

    A custom 30-06 Springfield Target Rifle

    gunsmith thought I should have something different than DGRs, so I ended up with this... The scope is an original Unertl 16x with adjustable parallax. Kinda like sighting thru a straw:) But when that gets old, it has an original Redfield aperture sight with Globe front sight. Not quite a plains...

    A kinda different 256 Newton

    My gunsmith thought a 256 Newton would be a nice rifle to have. I looked into Charles Newton and he seemed like a guy to build a rifle after. Then, my favorite book is "Elephant Hunting in East Equatorial Africa by Arthur Neumann" and the chapter on Lake Rudolph of his goring by a cow elephant...
