I am just beginning to get into reloading and I will have some questions.
Here is my first one. For beginning I thought of using IMR 8208 and it has some good reviews and then Serra bullets.
Hodgdon’s web site has 4 different loads using this combination and was thinking of doing about 50 each to have on hand for starters. They are a plinking round, varmint , large game and target rounds
The one thing missing from the charts are what primers to use. Is there a guideline if no primer is listed like using any standard large rifle primer?
That is what I have done in the past, when no specific primer is listed anywhere then I use the standard large rifle primer I have available. Of late I have had to substitute magnum primers so when working up these loads I knocked off 10% on the powder, this is being conservative. Looking at posts on different reloading sites many claim one brand primer to be hotter than the other, I load for accuracy and not speed so I just start working up from the minimum till I find that tight group for my rifle. So far the Hodgdon info has always functioned in my AR-10 from the minimum. With reloading components being in short supply I've had to work with lots of new combinations but no issues so far.... :pray:
Primers. Primers come in three varieties within a given size range.
Standard primers are good GP primers that can be used for most loads.
Magnum primers are used primarily for magnum loads and as JT said, standard charges if you back it off a little bit because these primers are hotter than a standard primer.
Benchrest primers. Primers marked as benchrest primers are more consistent because a little extra QA/QC goes into their construction. The shell on BR primers is made of a thinner material that makes it easier for the firing pin to penetrate and ignite the primer. Use care when loading these into a case, they're a bit more fragile than standard and magnum primers. Also use care with ammo loaded with BR primers - it's more susceptible to slamfires with rifles that use a floating firing pin (like an AR10/15.)
