How are you measuring velocity at 300 yards but not the muzzle? Won't a LabRadar give you a distance vs velocity plot? I may be missing something.

In other news, I built a bunch of rule bending loads for USPSA. I got an extended and ported Barsto .40 barrel for my X5, and loaded 135 gr Nosler JHPs with 9.6 of Longshot, which gets me about 1300 FPS. That's better than a 165 power factor, but it's pushing a bullet only 10 grains heavier than the 9mm shooters. My idea is that the extra gas through the ports will stabilize muzzle jump, much like the unlimited guys with .38 Supers and huge comps.

Last week I finished a 6.5 Creedmoor build for my dad on an old M700 action, and worked up a load. It puts 5 shot strings of 143 grain Hornady ELDX bullets into 0.3-0.5 MOA groups. I made dad 200 rounds, and will get it to him once Leupold finishes the custom dial.

I also finally got my model 70 back, and will soon start loading for that. I am really excited.

I have no LabRadar. I wished. The way the MV is Trued from Ballistic Drop is as follows. Say you start at a guess 3000 fps and you dial up 4 MOA, You shoot and the bullet is 3" below your target. 3" up at 300 yards is 1MOA, so you need to dial 5 MOA instead of 4.
You enter 5 MOA required at 300 yards into your Ballistic Calculator and it would return 2860 fps as trued MV. Note: All numbers are out of my head just to give an example.

We should buy one for DFW members and share it as needed. 6-members $100 each or have it at our best long range shooting club

Any reason you don't use a cheapo prochrono off amazon? It's like $80 for the chrono and $30 for a tripod. Beats the heck out of guesswork.

I have one with night LED lights and Wireless Bluetooth module. It was too hot to set it up. I did use it last time for my 30-06. Readings were all over the place, even when I was hitting the same target.

I will set it up the next visit and shoot at 300 and 400 yards with the same load. And, I will see how it goes. Last night I cleaned the 42 cases I shot and most likely I will develop a new load with a new powder. Candidate powders are IMR H4166 or RL 17.

Got my .300 Blk loads tested on Saturday. Interestingly, there was a guy next to me using 3 rifles with some very obnoxious muzzle-brakes that affected the recording of my own strings so I won't bother posting those screenshots, but the end results were these:

110gr Hornady V-max w/ 19.0gr H110 = avg 2,255 fps
125gr Sierra Pro-Hunter SP w/ 18.0gr H110 = avg 2,120 fps

I emptied 300 pieces of 45acp brass on Saturday... :lol:

and this afternoon I loaded 400 rounds of 45acp ammo.
