    Hunting & Fishing 375 wsm

    The 375 ruger in a 27" barrel is capable of 2,900 fps with a 260 gr Nosler accubond. We have built several rifles on this case and you can even go with a 350 gr SMK to about 2600 fps. The ruger case is very efficient and will treat you very well. Hornady even sell its 270 gr Dangerous game ammo...

    338-375 Ruger build ballistics

    I have been using 250 gr Hornady hpbt bullets and N570 powder and getting 3,000 fps safely. I have been as high as 3,130 but its a pain resizing after pressing the bullets in. I run a 26" Lawton barrel built on a Howa 1500 action.

    6.5 LRM or 6.5 LRM Improved

    I am thinking about having a reamer ground to neck the 7LRM down to 6.5. Maybe even improved it. Does anyone have any experience with doing this already. I believe it will push a 140 gr Berger at around 3,300 FPS. I know it will burn the throat quickly. But it should be fun anyways.

    Savage .338 Lapua Magnum

    Myself and some friends have different Savage 338 Lapua's. All of them will shoot .600"-.700" groups. They also favor the 300 grain bullet. Just don't load hot or you stick the bolt. Great rifles and for the money how can a guy complain with nearly 1/2 moa.

    375 tactical long range

    Just got the new 1-10" twist bench mark 28" Heavy barrel For the 375 Hammer. The other barrel shoots well but it kicks hard even with a break. So time to put the heavier one on. Its also an inch longer. I think I may try cutting edge 320 gr bullets. Hoping for 2850 Fps. With the same bc. It...

    375 tactical long range

    Well we got the 375 Hammer to push a 350 gr. SMK to 2,700 fps. No external pressure signs. But it hammers on both ends even with a break. I think I need a heavier chassis. And the 7 Demon runs about 3,050 with 180 Berger Hybrids. Having some pressure issues though I think the bullets are seated...

    375 tactical long range

    Yes its a 7mm X 375 Ruger mag. Basically the same as the 7 LRM. But I built my first wild cat on this case back in 2007. We named it Demon so we are sticking with this designation.

    338 Lapua Improved?????

    Rifle shoots 1/4 moa. Im leaving it right where it is in the 2980-3000 fps range. If it burns up a throat and some brass so be it. Ill just chuck it in the lathe and take a little off.

    338 Lapua Improved?????

    Seems like all of these rifles are performing about the same. And getting great results. Anyone else have any feeding issues. I have improved mine. But its still not Silky Smooth.

    375 tactical long range

    Parts have all arrived for the 7mm Demon. And its hunting season so trying to get everything done is going to be tricky. But When im done building and all of the R&D work I will post my results for all of the Ruger Mag Wildcats I have done. Load Data, Speeds and lets not forget problems. So look...

    375 tactical long range

    When I get home I am going to try a new powder and get that magic 2,700 FPS. Also I am going to build a 7 x 375 Demon. Im thinking a 22" barrel maybe 2,950 for speed with 180 berger.

    It is a 25" Sendero contour. Didn't have to hog out to much. A palm sander made short clean work of it
