    Range Report 5R Velocity Link?

    Could someone help me with the link that lists muzzle velocities for a Rem 700 5R using Federal 168 GM? I did a search, but can't find it. It had several posts with chrono results. Or, if anyone could throw a few my way.

    Range Report Velocity Drop With Muzzle Brake

    I just had a Badger FTE brake installed on my 24" .308. I really like the feel of the gun now. The brake has really tamed the "rifle hop" I was fighting previously. I was curious as to the velocity effect on my rounds. I'm running 155 Scenars and Lapua brass, 47.1 gr Varget, BR2 primers. Rounds...

    Range Report Velocity, Ballistics for 6.5 Grendal

    I just took my Grendal out for the 1st time and shot it over a Chrono. I am shooting Wold 123 Gr Soft Point Ammo. Average velocity for each of 2 ten shot strings is: 2465 and 2496, What is the BC of this bullet? Is there any free Ballistic Calculators that are good (I am scottish)

    Effect of twist rate on velocity

    Can anyone give me an idea of how much velocity I should expect to lose shooting the same load through a 16" 1:7 barrel as opposed to a 1:12 tube of the same length? I'm only getting 2650fps. from Sierra 55gr HPBTs over 26gr of W748 out of my Sig 556.

    Range Report .223, heavy bullets out of 16"bbl. What velocity??

    Any of you guys that shoot the heavy .223 bullets in your match guns ever throw them out of a 16" AR? I'm just wondering what velocities your seeing. Looking for mag fed loads only, no single loaders. Thanks Patrick Scott

    Adjust muzzle velocity for powder temperature..

    The following has been copied from a tip in the ballistic software Precision shooter workbench 4.. "In general, muzzle velocity will increase with increasing powder temperature and decrease as the powder temperature decreases. The "per degree" change of velocity depends upon a number of...

    Suppressors Factory velocity vs SubSonic velocity...

    In my first post on my .22 supressor it became painfully obivious that there was NO snaptic connection in my thought processes! For one reason or another the importance of Sub-sonic FAILED to imprint in my cerebral gray-matter. I had a new .22 Suppressor. Waves of 'thrill' made my trigger...

    Range Report 300WM +155's = ??? velocity

    What kind of velocity are you guys getting w/ the 155 grain bullets in your 300 Win Mags? I've always shot the heavier bullets, but would like some real world velocity numbers to play with the dope and compare. Thanks, Brad

    OCW and velocity with different brass

    Once you find OCW for a given brass, is it a general rule of thumb that if you change brass (lower or higher capacity brass) and load to achieve the same muzzle velocity then you are also at OCW for the new brass? (i.e.: once you have found OCW, just aim for that same velocity regardless of...

    Warm vs. cold Velocity's

    Kind long, but bear with me. I just did an experiment with my 300 WM & H-Retumbo. Some may remember that I asked a question about cold velocity's a while ago, as my pet load of 78gr H-Retumbo with 208 A-Max that usually gives 2911 fps had changed. That load was tested in 50* temps. During the...

    velocity matters?

    How critical is velocity related to accuracy? I started loading my .308 with 150gr bullets at the most velocity I could get out of it, I have since started backing down a little. I am around 2750-2800 now. I use this rifle as a hunting rifle mostly, but I do like to see how good I can get at...

    Velocity help

    Not sure if this is the right place but I do not own a chronograph and would like to know the avarage velocity of two of my rifles. I understand these vary form each gun but I would like an approximate value. I shoot FGMM 168s out of each gun. First is Rem with a 26 inch barrel. The other is...

    Velocity increase.. Why??

    My Lawton 260 chronoed 2815 fps on a 70 degree day using 47.8 gr of h4831sc and 139 gr lapua scenars. load shoots great. was trying some 140 gr a-max and h4350 the other day through a chrono. velocity was 2825. Decided to shoot the lapua load as a referrence. To my surprise velocity had...

    Velocity Change in the wrong direction?

    This weekend I was load testing and fired 50 rounds, 5 shots each, per .1 grain of powder. I came up with an odd result. All rounds were loaded in the same sitting from the same batch of once fired fully prepped brass, that was also prepped in the same sitting. All shooting was done in the...

    maxium velocity

    I am thinking about rebarreling a savage rifle. Is there a point when longer barrels are to much.What i mean is i have heard much debate between 20"24"26".I have also heard stories about 30" tubes.wouldnt 30" kind of be overkill with powder burn and all how far can a 308 bullet travel down the...

    223AI velocity gains over the 223?

    Has anyone used both these chambering's, and what is the realistic velocity difference between the two? I'm trying to decide which reamer to run into barrel that will arrive in a few weeks. It's an 8 twist barrel and I will probably use the 75gr A-Max as my primary bullet in the rifle. Thanks.
