Thread: ADI powder for 7RM

To be honest I reckon you are using the wrong powder in my opinion. I don't this 13 is going to get you the velocities you are after with that weight of projectile and that barrel length.

I personally use 2225, I think it's a better choice for the heavier slugs when you have barrel length to play with.
I'm using a 24" tube and have had a couple of good loads,

72gr of 2225 behind a 154sst was a great one,
73.5gr of 2225 behind 162 A max worked well too.

Of course this is in my shooter and the loads are hot so you should stick to the load data first before working up to pressures like that.

My two cents anyhow

hey man im about to get onto a different powder now, im goin with reloader 25 ? wit hthe 26 inch barrel and 162 gr eldx.....
thanks for this info, its a bit of a trend between published data accuracy and as you an few others find, that true magnum bracket with a bit of stoking an careful experimenting to get it humming.

ive also got Hornady brass now which is nice to start with neat stuff.
using Rem 9 1/2 primers..... might change? the 2213sc was cratering them at 63? but no other sign of pressure, so to speak.
