Powder question for 7mm Rem Mag

Well Im goin to begin reloading for a 7mm Rem Mag. I have the redding competition 3 piec die set, as well as the competition shell holders, this will be my first time using these sets, always been rcbs equip. before, and I have heard amazing things about them. I also have the bullets down to #1 choice the 140 gr accubonds, #2 160 gr accubonds. So now Im looking at choosing a powder to start with. Im thinking of using ramshots magnum. I am looking for a very temp stable powder that will hopefully give me low ES and still gave great velocity potential. It appears that the RL powders give the best velocity but I have heard they aren't the most temp stable (?) My next choice would be retumbo, then H-1000 as I've heard these are very stable or insensitive maybe a better way to describe it. So just was wondering what peoples expierences are with these or other powder in the 7 Rem mag and if Im going in the right direction. Any advise on these powders , or bullets or componets for that matter, would be greatly appreciated. Thank you

Re: Powder question for 7mm Rem Mag

I shoot a 7 Rem Mag with 168 Bergers. I tried Retumbo and it was not consistent with respect to ES. H-1000 gives me single digit ES and is consistent with all types of conditions. H 4831sc worked pretty well too. I would think that these powders would work well with 160 Accubonds also. Hope this helps.

Re: Powder question for 7mm Rem Mag

what kind of velocity are you getting with h-1000? The other question I had with the h-1000 and retumbo was I thought they were better suited to the heavier bullets compared to my 140 but after looking through the manufactures websited they really weren't that far behind the RL numbers, so maybe that is a misconception (?) thank you

I use RL-22 with Federal 210M primers and 140 and 160 gr. bullets in my 7mm Rem. Mag. with good results. I don't remember what velocity I got. My shooting has been in Ohio with probably 50 to 90 degree temperatures and, at least in that temperature range, I've had no problem with temperature sensitivity.

I get 3020 fps with 69.1 g of H-1000 out of a 26" Lilja and 168 VLD's. Not sure how 160 AB's would work but I would think pretty well.

Re: Powder question for 7mm Rem Mag

I have loaded for the 7Mag for approx. 15yrs. In that time I have tried alot of different powders and by far the best accuracy and velocity has been with IMR 4350, IMR 4831 and RL22. I have mainly used the 150gn Ballistic Tip for all of my target, varmint and deer hunting with this round. JohnnyK.
