    NEW TOPIC: Increased Air Pressure on the Front ..

    Re: NEW TOPIC: Increased Air Pressure on the Front .. The ammo temp did go down, H1000 was the powder in those loads, which is temp stable for the most part. Biggest issue was much denser air at that air temp. Not sure about the angle of the keyholes, it's in the subsonic range. You can...

    I wonder if this would help keep the peace in those underground long term hide sites? Won't do much for the quality of air issues though. Enjoy Solution for Bad Air in the Hide

    .338 Lapua over .300 WM?

    Re: .338 Lapua over .300 WM? lrs50bmg: I kind of banged on crane earlier, but I have to say that in the field of sniper weapons systems, they have done a very fine job as well as ammo for those things. "we" were pushing for the 338/416 in the late 80s, crane wanted to do the 300 win mag...

    NEW TOPIC: Increased Air Pressure on the Front ..

    Re: NEW TOPIC: Increased Air Pressure on the Front .. Here are a couple of examples of how fast the 300 gr. and other long projectiles can destabilize. The 1540 yd group is about 50 yards short of the calculated transition point. 1500 is about 50 yards PAST supersonic transitional range...

    Re: NEW TOPIC: Increased Air Pressure on the Front .. Mechanic... touchdown. The tungsten core does raise the SD of the projectile, same length as the Mk211 and M33 Ball, but because of the badly selected 1:15" twist for nearly all .50 BMG barrels, the higher SD is better stabilized over...

    .338 Lapua over .300 WM?

    Re: .338 Lapua over .300 WM? Hey guys, here are some real numbers based on radar data for these two rounds. 338 Lapua with the 300 gr. SMK is the clear winner, it's not close to 1500. 220 gr. Sierra MK @ 2860 fps: Velocity at Supersonic Range 1122 fps, transitional limit is 1520 yards...

    NEW TOPIC: Increased Air Pressure on the Front ..

    Re: NEW TOPIC: Increased Air Pressure on the Front .. Tribe, Good observation, the above .50 round is the M8 API, which has one of the highest BCs of the conventional .50 rounds. It is better than the much talked about Mk211-MOD-0 round. The average 3000 yard BC is .709, well above the...

    Re: NEW TOPIC: Increased Air Pressure on the Front .. Sure, A couple of examples of this zone are: 7.62mm M118 and M118 LR rounds, 1000 yards supersonic range, the final critical zone of the supersonic range is 900-975, guesswork is okay to 750, past 750 requires math and serious thinking...

    NEW TOPIC: Increased Air Pressure on the Front ..

    Re: NEW TOPIC: Increased Air Pressure on the Front .. Yes, if you put a different ammo temp into the program (70 is the standard), the program will vary the MV based on the ammo temp. This is based on military cartridges that are selected on a curve or temp range variations. It's not...

    Re: NEW TOPIC: Increased Air Pressure on the Front .. Mechanic and other shooters, The Cheytac ABC uses a different BC value every 100 yards or meters. As the range is input, the program calculates and extracts the exact BC value between listed values (interpolation), then corrects that BC...

    NEW TOPIC: Increased Air Pressure on the Front ..

    Re: NEW TOPIC: Increased Air Pressure on the Front .. Just a quick note on these ballistic calculators, they ALL use a singular BC value, based on some factory or a near downrange remaining velocity calculation. With the exception of the CheyTac ABC / CABC, none of these calculators are...

    Re: Back from the dead Hey there, long time no see!! That ball and chain was more like a barbed wire enema!! I'd take the company of bad guys, them I understand and they're clear with their intentions, you know what I mean. Going over the ocean in early July, gone for about 4 weeks, then...

    Re: NEW TOPIC: Increased Air Pressure on the Front .. Concerning this observation... "A pure head/tail wind has virtually no effect on the ballistic trajectory. To the extent that there is a vertical component, such as a severe slope in front of the shooter, it's value is the same as a...

    Re: NEW TOPIC: Increased Air Pressure on the Front .. Cory, Quibble all you want, you're wrong all your observations. How much mountain shooting time do you do? At ranges that are within the last 15-25% of supersonic? Suppressor comment, sorry, but measured with highspeed video UNDER...

    Re: NEW TOPIC: Increased Air Pressure on the Front .. Mechanic: Your point is a good one. At extreme ranges in a military environment, or whatever environment you're shooting at something that is living, flight time is everything (to me). I evaluate everything from a "how long does the...
