same load same bullet same velocity, It is an excellent powder for reduced loads and cast bullets.

That's interesting since when? would that be the same for all IMR powders? I would air on the side of caution as there is likely to be lots of old style IMR still for sale and none of the reloading pams have been updated to suggest this?

Ive been playing with the Gordons reloading tool today, its quite neat, and free.

One question for the guru's...The calculated velocity is a bit different from measured. What variable/s should I tweak to get things to match?


Lots of red words and warning signs in my initial load setups, but it looks better once actual case capacity etc are entered.

check bullet length is actually as measured then adjust the "initial pressure"

@johnd I have just started using Gordon’s reloading tool, and you say for this example if he used 58.95grains he would have a accuracy node, what data on Gordon’s reloading tool says that it is a accuracy node?
There is a lot of info on Gordon’s reloading tool so just trying to get my head around all the info in it.
Cheers

Greetings All,
I have read through this thread with a bit of amusement and have a suggestion. Perhaps it would just be easier to load 38 grains of AR2206H behind the selected projectile and fire it over a chronograph. This will give the actual velocity in your rifle with your lot of powder and your projectiles. I used that load behind the 150 grain projectile and chronographed 2,380 fps in a 22 inch barrel, a nice soft target load. My rifle has a longish throat. With the lighter projectile and shorter barrel that would work out to about 2,350 fps. Hodgdon also published a load of 38 grains of H4895 (AR2206H) behind a 125 grain projectile for 2,592 fps in a 24 inch barrel. This works back to about 2,400 fps in a 16 inch barrel. The predictions of around 2,200 fps looks light to me. My load burnt a bit dirty but was nicely accurate. Cases could be neck sized forever just needing annealing from time to time.

@Blair look along the top row, there is a feature called OBT which stands for Optimal Barrel Time.
In THEORY this gives accuracy nodes based on the harmonics of the barrel length.
Dont know how true it is, but is as good a place to start as any.
