556 Ballistic Table? There is a 556 Table/chart (not a graph) floating around here that has the different mil-ammo info with barrel lengths,velocity, +/- drops, etc. for different Zeros. I believe it is printed in black, blue, red and green print type. Can't find it anyone have it? link? I found that I had already pulled it and just not labeled ...
Despite the research I've done, I'm still curious if anyone could comment on the differences I might see in trajectory between the two calibers out to about 300 yards given the following options: 11.5" Barrel shooting 62gr 5.56 (TSX, Gold-Dot/Fusion) vs. 10.5" barrel shooting 110gr 300 Blackout?
Alliant load data. 69 grain bullet. AR-Comp - 23.2 gr - 2969 fps. 68 grain bullet. AR-Comp - 23.4 gr - 2969 fps. Alliant does have load data for bullets heavier than 55 grains with Power Pro Varmint but does have 68 and 69 grain bullet data for Power Pro 2000 MR that looks a lot like the Hornady PP Varmint data.
Unfortunately you may HAVE to put more rounds in the threat due to the lack of damage the projectile causes. The 5.56 is far more effective at getting the attention of men than 5.7 mm. This is not speculation. We have been using 30 P90's for five years now. There have been multiple BG's shot with them.
How different are the two if say they are equipped with the same 55 grain bullet? Will the 223 have more drop?
Hi Guys, does anyone have or know where I can get a bullet trajectory chart for .30-06 projectile. I have a bolt action in this caliber and want to start using it. Would also appreciate any recommendations on what distance is normally used for zero with this caliber. I'm assuming 200yrds for starters. Thanks for any help.
The TBBC as previously noted, Win 64gr solid base bonded Q3313, BH 50gr TSX, and Hornady 55gr GMX. We’ve previously issued 64 gr Gold Dot and currently use Federal XM223SP1 out of Colt M4’s with both 14.5” and 11.5” barrels. For training/quails we use a 62 gr OTM round supplies by Winchester.
Feedback Score. 28 (100%) The elevation and deflection adjustments are in inches per meter. The BDC itself is neither, it is based on 19" at 100 meter intervals with the intervals in accord with trajectory. You can backward engineer the reticle into Mil or MOA if you want to, but it's kinda pointless.
11.5+” barrel, 556 when possible If you need to go below 10”, 300 offers better ballistics, and adds subsonic capability. Once I build a 300, its to bridge the gap between an 11.5/10.3 556 and a 9mm subgun or handgun. As with anything else, there are inherent limitations, and personal limitations.
Feedback Score. 13 (100%) Highly accurate 77gr loads, barrel twist limits. My M&P15 16" barrel is 1 in 9" twist and I'm wanting to load some highly accurate 223/5.56 rounds that will push 500 yds. I'm thinking of going with a 77gr bullet, but I'm afraid the 1/9 twist won't stabilize the bullet enough to be as accurate as I want at this distance ...
