The sierra manual accuracy load is a good place to start. As said before the nosler accuracy load too.
2 weeks is plenty of time however knowing what bullet you are using the twist of your barrel would make this quicker.Im looking for speedy process suggestions not component suggestions. I have the components ironed out but thanks for the suggestion. The main concern is getting a load worked up in the two week time period.
I don't know your rifle at all so this might sound stupid, but make sure your loads will fit in the magazine (if that is appropriate).I would find your lands. Then start .020 off. Seat bullets in .005 increments deeper and shoot 3 shot groups until you find the best one. Then start with powder. Pick your powder of choice, start 2gr under max, load from 2gr under max to book max in 0.5gr increments. Stop if you hit pressure. Pick the load that either has the lowest ES or the load that meets your velocity goals and still has low ES. If you're only shooting 300 yards, I would focus more on accuracy than an ES that's low. Anything with an ES under 30 will be good enough.
Very good point. If your rounds at .020 off are too long, then seat .020 shorter than max magazine length and then work back from there.I don't know your rifle at all so this might sound stupid, but make sure your loads will fit in the magazine (if that is appropriate).
Go here and you'll have a load in two trips. It's a proven method of LR load development. I found it works out to 700 yards.
Should be pretty easy if you pick your bullet, load by the book/medium charge to start. You only need 1 to 1.5 minute accuracy at your max range. Use chronograph if you have one to verify, otherwise you should be fineOk heres the deal, I have two weeks to get a load together for a rifle that traditionally has given me fits in terms of reloading. Max range for the upcoming hunt will probably be 300 or less. Gun in question is Ruger Mk II in 257 Rob AI. It has a new quality barrel hence the AI and less than 50 rounds through it.
What is the quickest most efficient way to iron out a load in your opinion? I am open to suggestions because in the past I have never been under time constraints to find a load and needless to say it wasn't done in a timely fashion. For what its worth, I have some fire formed winchester brass, 1x fired, and non fire formed Nosler brass. Only have access to a 200 yard range for the next two weeks and a limited time to be at it, maybe 2-3 trips max. I have a magnetospeed for data collection as well.
What would be your methodology if you were in my position?
The best and quickest would be to use Quickload or GRT.Ok heres the deal, I have two weeks to get a load together for a rifle that traditionally has given me fits in terms of reloading.
