ADG Brass

[Bominiscious]

Bought a bag of each of Starline, Hornady and ADG Premium 7 rem mag brass from Scheels. I am still very new to the reloading/handloading game and to this point I have only loaded 1x fired stuff. This will be my first time loading new unprimed brass.

Not even sure what to ask, but just wondering if there's anything I should know, or do differently. Loading for two rifles, a T3X and a Ruger M77 Hawkeye, and loading for hunting deer and hogs. Bullets will be 160 Accubonds, 160 Partitions, and 140 TTSX's. Powder on hand is IMR4350, H4831sc, and H-1000.

I'd stick with ADG and move forward as usual.

Treat each batch of brass as a completely seperate load- rifle- combo.

ADG usually takes less powder to reach your speed or pressure.

For example (pure guess in your situation...)

All the same powder and bullet...

Hornady- 70gr
Starline- 69 gr
ADG - 68 grains of powder

This may be max load so if you tried 70 grains in ADG, which worked in hornady, you find out is way over pressure.

I would stick to one brand of brass and don't mess with the other ones, you might end of chasing your tail trying to find loads that worked in one brass but not the other and you might end up at over pressure and risk hurting yourself.

Very helpful. Thank you.

Go easy on the first load (s) to fireform. I have found with ADG specifically, if I reach pressure with virgin cases, they are waay over.

I'd use one brand for each of the 2 rifles. It's usually not as simple as loading one load that will work in 2 different rifles.
ADG is quality brass but I have had good luck with starline brass in the 223.
You may need to back off your powder charge after your first firing.

nothing wrong with any of the brass you bought. you will have to work up a load for each brand because it won't be the same for each. pick two brands one for each gun and keep them separate. don't mix brass between guns. Starline has outlasted Hornady but ADG never seems to be available when you need it so which ever you decide on buy at least 100 each of the same lot.

ADG is best of your choices. I'd either sell the others and purchase more premium brass, or put it on the shelf for the day you can't get anything better.

As others have stated, ADG brass will generally use less powder to reach the same pressure/velocity, so reduce charge weights from what you are used to. This is part of the equation and why reloading manuals give specific "recipes" in their manual. Changing any single component can have great influence in the outcome.

Also, ensure you have a couple firings on your brass before doing your max pressure testing, as virgin brass will "absorb" some of the pressure in forming to your chamber.

Think I will go ahead and buy another couple boxes of ADG based on feedback I'm getting here. Love this forum. Been so helpful on this new reloading journey.

Just re-read your first post. As it is a 7RM, definitely go easy on it as the belted mags "move" a bit on the first firing. Another option is Peterson. They have "long" brass that is already really close to the length of fired cases for belted mags.

Of the three powders and the bullets you mentioned, I lean towards H1000 if you're looking for the higher velocity. 4831Sc is also good with those bullet weights but gonna be slightly slower. I find to be best in 300wsm and H1000 in 300wm. H4350 is very good and temp stanle in just about any .30cal if you aren't looking for max velocity. It's usually gonna be 100 to 200fps or so slower than the other two.
I've loaded Hornady and Starline brass prolifically. I would definitely choose Starline over Hornady.
I just loaded my first batch of ADG in my 6.8 Western and so far I'm pleased. The case wall is slightly thicker than the Win brass I've been having to use, especially at the neck. So, as mentioned, due to thicker brass the case volume is slightly lower which results in a grain or so less powder needed to reach the same velocity.
I also did not have to trim a single case. They were all within 0.003 of each other and after ream and deburr they were just over trim length.

ADG states to start at minimums and work up as the volume of their cases is smaller.
