    GS Custom Solids for 375 Cheytac

    Re: GS Custom Solids for 375 Cheytac Thanks Dave. If a Lost River Bore is .367" diameter bore, would the groove diameter then be 0.375"? That would be the standard CIP spec for a 378 Weatherby Mag. From the CIP spec below we see that the USA 375 barrels are specified at a groove diameter of...

    GS Custom Solids for 375 Cheytac

    Re: GS Custom Solids for 375 Cheytac Hi Wade, I have seen references to a "Lost River Bore" a number of times but cannot find any specific dimensions. GSC bullets are intended for standard SAAMI and CIP specification barrels. Therefore we build to conform to a bore diameter of .367" and a...

    Firearm Poll

    We need some help here. This is a badly worded poll and, as a result, the "Yes" votes are lagging behind. A hand will be appreciated. Middle column a short way down the page. http://www.news24.com/

    5000 meters+ Supersonic (*Updated with pics*)

    Re: 5000 meters+ Supersonic TJ Your question is directed at Anthony but he may be unaware of this development. There is a gap between the 308137SP and the 308158SP and it is being bridged at the moment. Ideally, the 137 is a 12 to 13 twist bullet and the 158 is a 10 to 11 bullet. We need...

    Range Report What "the trace" is and how to see it

    Re: What "the trace" is and how to see it Thanks for the time input to all. The effect of rifling engraving is not well covered and little is available. It may be because it is perhaps less important than what is thought, or it may be that the importance is not fully realised. In addition...

    Re: 5000 meters+ Supersonic Groper, I ask myself why you are so threatened by this, that you would stoop to the level where you question the ethics of those involved in the project. You have raised nothing but objections and obstacles. You are unnecessarily insulting and downright rude. I...

    5000 meters+ Supersonic (*Updated with pics*)

    Re: 5000 meters+ Supersonic Steyr IWS 2000 costs $14,000.00 I wonder what the ammo costs. It weighs 40lbs. 5lbs less than the 14.5. Whoopee.

    Range Report Shooting CNC Lathed Solids from .338 Lapua

    Re: Shooting CNC Lathed Solids from .338 Lapua Heavy barrel wear is not a given with all monometallic bullets. A good indication is the engraving pressure (shot start pressure) of the bullet. Lead core bullets typically have a shot start pressures around 3500psi. A drive band, turned...

    GS Custom 414gn MK 2 Bullet Test

    Re: GS Custom 414gn MK 2 Bullet Test Lowlight, Using multiple surfaces are a good idea when static stability needs to be checked. One can then see to what extent the bullet is yawing and at what distance the precession cycles dampen out, if indeed they do so. Here we are interested in the...
