Staball-HD is close to Retumbo. Staball-Match is close to Varget. The two are a world apart.

The top of my useless list has 308 win and 30-06 on it.

barrel length is not relevant to spin stability other than the velocity it generates. Go to the JBM online twist stability calculator. That one handles plastic tipped as well as all metal bullets.

The amount of powder, primers, etc bought by reloaders is miniscule compared to the amounts bought by governments. We are lucky to get any of what's left.

your inputs are different. There is no way any modern external ballistics app will be more than 1 click different with the same inputs.

If there had been a 6.5-06 at the time the 270 was introduced, there would not be a .270 win today. I had a 270 win as my first deer rifle. I built a 6.5-270 a few years ago and it is my favorite rifle now. The 277 caliber has always been an odd duck. 25 cal is a bit small. The Swedes have been...

This was my first load for Staball-HD in 300 WM. 200gr ELD-X. As of a couple days ago I have a load for 208fr ELD-M also.

I bought a Howa mini in .223 last year. I have at least 10 centerfire rifles and this one is the first one I ever was not able to develop a decent load for. I have 3 other 223s even. Mine was a 22" #2 contour. The barrel just had too much vibration. I swapped the .223 for a 17 fireball in a #3...

I shot p-dogs last Thurs on public land with a lot of driving and checking old spots that were now bare and I shot 100 rounds. If we had stayed in one place 200 rounds would have been easy. On private land you can shoot 200 rounds and hit 100 p-dogs in a day easily.

BC changes as velocity changes anyway. There is no single BC value for a bullet that works for the entire trajectory.

G7 BC for the 53 bg Vmax is about 0.130. But you're gonna need a 1:9 twist to spin that 62 gr ELD-VT

This new 62gr ELD-VT is going to kick the 53gr Vmax off the highest BC varmint bullet throne.

.17 hornet to 250 yds. 17 fireball to 350 yds. .223 to 400 yds. 223 AI to 450 yds. 22-250 to 600 yds. 6mm creedmoore past that. Those cover it for me with 90% being the 17s.

When the primer cups look like poured pancake batter, that is a real sign of high pressure. Should see case extrusion into the ejector hole too.

An ice pick into your ear does not expand either
