22-250 in AR10. 6 ARC in AR15

Thats good to know. That explains why it never would work with my new galaxy s10 phone. I just use it with my older samsung phone. But I believe my problem is a hardware problem, specifically with the cable. Edit...it worked for about the first 10 times I used it.

I bought a teslong about 6 months ago and its already going to crap. It will start up and work for a few seconds until the picture starts blinking and cutting out then it says camera disconnected. I think its an issue with the cable or the mini-usb connector as it gets worse as I move it...

The left is arming themselves. Not only that, but the leftist powerful and wealthy are building up supplies of arms and ammunition. There are antifa militias forming and training and being funded and supplied by these entities. They would still be outgunned, but never underestimate the enemy...

I just actually found a friend locally has an annealing machine, so Im going to take them there and aneal them. Very nice of you to offer. Thanks.

I have looked into it. For the rare frequency and the small volume I dont think Im pulling the trigger on that yet. Do you use the salt bath?

Have you dealt with?

I am looking for somewhere to send a small batch of rifle brass for annealing. Anyone know of such a service? Hopeful to find one that uses an amp induction annealer or something similar.

I used to think this way about SD and ES. After studying statistics related to shooting, I realise now SD is actually more meaningful than ES. For example. First of all, rifles are like random number generators, If you fire enough shots and graph them, the population will have a bell...

Good write up. I enjoy seeing real data. Just a suggestion, but I think SD tells you more than ES because it uses every data point, where ES throws out all but the hi/lo points. I see SDs around 5 with un-annealed lapua brass in my 6.5 cm, using H4350. Using a chargemaster lite. I just...

Leaving mass out of the B.C. equation would defy physics. "Heavier objects do not fall faster than lighter objects when they are dropped from a certain height IF there is no resistance from the air. ... Because of this, the resistance from the air slows the fall of the lighter thing. But if...

Sectional density is not used in BC calculation. The formula is actually the BC= mass/Cd*A. Cd= coefficient of drag, A=cross section. The Cd is determined by the shape of the projectile, which is a very important factor. Its impossible to create a copper projectile with the same mass as a...

Mass=volume x density. Lead has a significantly higher density than copper. Thus leading to higher B.C. with the same shape. B.C. Calculation is affected by the mass of the projectile. See above link but here is the breakdown "The Math / Science Ballistics is the science of mechanics...

Weight has a large effect on B.C. Copper is less dense than lead. The copper bullets will never perform the same as the lead core bullets with vld profiles.

Wow. Thats very reasonable. I could almost justify that even if I only made it a few times per year.
