Reloading Question:

bgrivrs

I am new to this forum, and have question about reloading. I have
been reloading all my ammo for my 7mm Remington magnum for several
years. I am changing to a 7mm-08, and need to know which primer I
need to use. I think it will be the large rifle primer, but can
I use the magnum primers I have for my 7mag, or would this cause to
hot an ignition? I know you can't use large rifle primers for magnum
calibers.

first and foremost you need a manual. however you can use a mag primer with the slower powders.

I agree with the above post, get yourself a manual. Often times you can get them from the powder manufacturer for free! The only time that I would use magnum large rifle primers in a standard rifle case is if I had a lot of unburnt powder residue left in the barrel. Most of the time I just ghange to a faster burning powder and start over.

Why should we set ourselves up for a potenial accicedent when one can be avoided!

If you ain't got a sense of humor you got no business bein here!

A standard large rifle primer will ignite all the powder you can get in a 7mm-08 case..........................Using a magnum primer may run pressure up slightly and is not needed, but as mentioned above use what is listed in a good manual........good luck........[8D]

Hey, I reloaded 8mm Mauser when I was a kid without a manual for years...using a Lee hand/hammer loader with a single scoop and the recommended powder. Same for my 12 Gauge ammo at that time.

But, the other posts are correct, if you have a complete loading press/dies/etc.setup, then spend a few bucks and get a good manual. I would also recommend that you also pick up different one, either now or a little later. If you read it through, you will pick up a few new tips and some polish for your existing routines.

I have loaded some high volume charges with standard primers that worked fine in many cases (no pun), then in others the mag primer was needed. Most of the time it is a powder issue. Just because you are loading a 'mag' caliber, a 'mag' primer is not a given necessity.



If we do not hang together,
We will most certainly hang separately.

Hello:
I'm currently building a load for a 6mm using a magnum primer & 100 grain bullet. I tested a standard primer, but in my particular application was ending up with unburned powder due to barrel length (18 12/"). At 38 grains of IMR 4064 my groups widened, but no signs of case pressure with a standard primer. When I substituted to a magnum primer and SLOWLY worked up the groups closed; but the medium range load of 36.5 grains held tighter groups. My suggestion would be to start at the low end of the recommended load (everyone is right you could use several loading manuals) and work up from there with a magnum primer. Several experienced loaders I know run only magnum primers. I don't think this is the answer as the best groups I've ever shot in my 220 Swift used standard CCI primers, and a medium load. When I switched to magnum primers in the Swift, there were definite signs of case pressure. Faster is not always better; but you'll probably find that most loads you build will group tighter just about the same time you start to see pressure signs. Again the caveat to work up slowly. To complicate the mix all primers are not the same. Time and again I've substituted Federal magnum primers for CCI magnum primers, and ended up with case pressure signs even with medium loads. The first 30+ pages of my Hornady & Speer reloading manuals contain such a wealth of information, that I often reread them before starting any load project. The variables are infinite (and some times maddening); but that is half the fun. There's a combination out there for each individual rifle, that you'll never find in a factory load. Worth the effort in my opinion!

I have been reloading for years, and have manuals. I just have not
used them, since I have been loading the government issue powders
which are not listed in the manuals I have. I will check my Nosler
manual for the proper loading info. Thanks for all the advice.

140 grain bullets over a charge of H-varget or H-4895 and a large rifle primer of your choice(I like the winchester wlr in my 7-08) will make the 7-08 sing. after that magnum your shoulder will thank you for the change. And you will be impressed with that 7-08. I have several one shot kills at a tad under 400yds. With plenty of practice, it should not be a problem. The caliber is certainly capable.

Everyone has a photographic memory. Only some have film.

Sierra has an excellent manual and in one of the chapters it goes in depth on the use of Magnum primers vs. standard large rifle, I think it was equal to 2 grains of powder, but please don't rely on my poor memory look it up. Also it has a rate of burn chart for powders that I've found very useful for developing loads with powders that aren't listed for a particular round. Sounds like fun, you should be able to develop a shootable load with what you have if you do your research. Seems like you have a quantity of powder and primers you are looking to utilize with your new rifle.

It all depends on the powder you are using,that's why you need a manual
