    Rifle Scopes New Nightforce "B.E.A.S.T." & ATACR

    Re: New Nightforce "B.E.A.S.T." & ATACR I and many others are very satisfied with Nightforce. They are a tough scope and the clicks repeat. Until we can get the new models in our hands we don't have many facts. I am sure the R&D on top end scopes is extremely costly. The odds are good...

    Most Accurate big bore for less than $20K

    Re: Most Accurate big bore for less than $20K The challenges of half minute accuracy at 2500 yards are overwhelming. The variations acting on the projectile become more serious with each unit of distance. Even if you use return to battery testing platforms (which I have a lot of experience...

    New 2 Mile 50 cal bullet?

    Re: New 2 Mile 50 cal bullet? I would be very careful with this projectile. There is going to be a LOT of pressure. This type of stuff is tested remotely in a pressure fixture in a test box. I agree with Noel on this one. I am guessing around 1000-1050 gr and about 2400fps. The pressure...

    338 Bullet Testing / Demonstration LV Nev.

    Re: 338 Bullet Testing / Demonstration LV Nev. Noel If any banded projectile design shows a higher BC than a comparable weight jacketed bullet in head to head tests then I would certainly acknowledge a superior design. I hoped I had made that clear in my last post. I have seen no...

    338 Bullet Testing / Demonstration LV Nev.

    Re: 338 Bullet Testing / Demonstration LV Nev. Noel I know that you are well aware of the challenges of making high quality bullets. As for any specific bullet design the best one can do is model the bullet and project how it will perform. Testing is the only method to determine how well...

    338 Bullet Testing / Demonstration LV Nev.

    Re: 338 Bullet Testing / Demonstration LV Nev. It is good to see some straight data. I was not surprised to see that solids with bands did not do as well as hoped. As one earlier poster stated bands can be called "drag bands." Any gain in muzzle velocity will be lost to drag. With the...

    Caliber Choices - Comparison and Applications

    Re: Caliber Choices - Comparison and Applications I think everyone owes Bohem thanks for this thread. I suggested the 6BR and anyone can see my comments on an earlier page. Bohem is totally correct that the BR does not work well in repeaters. Perhaps it would be useful to make a short list...

    Gunsmithing Making a tapered base

    I am trying to figure out how much taper per inch is needed on a base to equal 20 MOA at 100 yards. If one ignores the distance between the center of bore to center of scope I come up with the following. 3600 inches = 100 yards taper of .006 per inch would decline the sight line by 21.6...

    Does anyone know the history of the Remington 788?

    Re: Does anyone know the history of the Remington 788? Get a copy of "The Bolt Action" by Otteson. He has a good discussion on the 788. They were very accurate and had a fast lock time. They actually cost more to make than the Remington 700. I have owned several and I wish I had not...

    Caliber Choices - Comparison and Applications

    Re: Caliber Choices - Comparison and Applications I normally lurk but I will give a viewpoint. I made rifle barrels all my adult life. I am now old, retired, and nearly dead. I have shot from 22 rimfire to the 50 BMG. I suggest the 6BR. Pro: Cheap to shoot Extremely accurate. Most...

    Information on mechanical rifle accuracy machines

    I am not sure what forum to ask this question. I am interested in rifle accuracy testing machines used by the military. For example, a picture of a Mann machine rest is shown in Hatchers Notebook. I have been told that the Army Marksmanship Unit has a machine called "the sled." Does anyone...

    machine rests for testing accuracy

    I am interested in the old machine rests like the Mann rest photographed in Hatchers Notebook. I was told the Army has a machine rest known as "the sled." Has anyone seen this unit? Information and descriptions would be great. jerry1

    Awesome Mosin Nagant footage.

    Re: Awesome Mosin Nagant footage. I owned a Mosin Nagant many years ago. I altered the bolt and had to do some mount work to allow scope use. I am a machinist and made rifle barrels for a living. I am now retired. I used a Leupold scope. That Nagant was a very accurate rifle. The Mosin...
