Thread: Best/simplest alternative to a ladder chart?

Greetings @Tentman.
Regarding BM8208 earlier data including that from Hodgdon and ADI seems to have used a powder that was faster than the current production. I ran into this when I was working up some loads for the 60 grain Vmax. The best data I have found is from an article in Handloader by Brian Pearce. This agreed with my chronographed results> Brian showed a max load of 26 grains of IMR8208 XBR (BM8208 in a different container) producing 3,251fps in a 22" barrel with the 55 grain Nosler BT. I have not chronographed the 55 grain with 8208. As far as the 55 grain Hornady projectile goes I have used a lot of them with good results in 3 different .223 rifles, one with a 1 in 8" twist, over the years but they are a bulk low cost alternative so quality may have suffered from time to time. Regardless you may have found a sweet spot around 25 grains so that could use some more testing. Brian used Hornady cases in his tests so there is one less variable.
