Looking to start reloading. This will be my first attempt.

Looking for some guidance/help with deciding how to begin a load development. I have a rifle that "likes" heavier/longer bullets so I'm looking to load some 50 and 55 grain Bergers as they're the only one that I know of that makes larger 204 bullets.

For instance, how do you determine what primer of all those to choose from to use?

If anyone has any experience as to ideal powder, primer etc., I'd appreciate it. This rifle is an AR with a White Oak upper that is a 1/10.

Thanks in advance.

I don't have experience with the .204 Ruger, but can offer some general insight that may help.

The primer does effect the load, but that's the least important component. Get the bullet and powder charge down first, then keep everything the same and change primers. Use every brand you can find with that same powder charge. Then follow the one with the best results.

Federal primers get a pretty bad rap for being soft. Not a desirable quality in an AR (slam fire). I've never used them in rifle, so I'm just repeating the monkey see monkey do internet thing. CCI primers haven't let me down yet in the small rifle world. :thumbsup:

As for choosing components in general, get several sources / reloading manuals... you'll start to see trends. Committing yourself to a heavy bullet for caliber with few manufacturers may mean there's very little data out there for you. Maybe try a 45 grain bullet first. :dunno:

The .204 is going to want medium burn rate powders. At a glance, I don't see any data on 50 or 55 grain bullets, but with the heavier stuff, it seems Varget, 748 and reloader 15 are getting the best velocities (they burn a little slower). Accuracy, you'll find, might be a different matter. Hopefully others with more experience in this cartridge will chime in soon.

Wait - google Hodgdon powder data and look it up - it has 50 grain Berger loads...

Here are some loading suggestions from Berger. Ideas as to these loads from your experience? Again, this is for an AR with a 26" barrel.

I use Ramshot TAC for my 204 loads. These have worked fine in my bolt gun.

Use Remington 7.5 or Wolf small rifle magnum primers, and avoid Winchester like the plague. CCI if that is all you have.
