I was lucky enough to find five boxes of factory Remington 250 Savage from the same lot for fire forming my 250 Savage AI. Accuracy was amazing and I took lost of ground hogs and two white tails during fire forming.
Honestly... with a premium barrel inside of 300yds, you could probably just pick a random charge weight from the book and be accurate enough to hit vitals inside of that range. You are seriously overthinking this.What did you test with your 50 fire formed brass?
As a new Reloader, I test seating depth while fire forming brass. I will also do basic powder charge weights. I then tweak powder charge with fired brass, and if needed I will play with final seating depth to shape group.
If I were you with only 2-3 range trips, I'd load at SAAMI length and do a powder charge work up in .3 grain increments. Choose the best one or two groups and verify those loads on the next trip.
Good luck,
Steve
I am mainly looking for an abbreviated method of finding a load. I highly recommend doing your research and learning as much as you can before you start loading. Ive been loading for years but being in a time crunch is a new situation for me. I am by no means an expert even after years of loading. Always learning. Good luck to you when you get started.
Shoot an Audette ladder, don't worry about the crony until you find your load.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. 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?
Agree with this ^^^100% unless the OP has unlimited time to dedicate over the next 2 weeks. I've always gotten very frustrated with trying to do a load development on a time crunch. Reloading and rushing just don't mix well. Stay safe and good luck.Honestly... with a premium barrel inside of 300yds, you could probably just pick a random charge weight from the book and be accurate enough to hit vitals inside of that range. You are seriously overthinking this.
In all seriousness though, since range is short relatively speaking, just do a simple charge weight ladder centered on the Nosler book "most accurate" charge weight for the powder/bullet, load 1-2rds each in .3gr increments and shoot with the chrono on looking for velocity flat spots. This will identify the most accurate "node" for your rifle/bullet/powder combo. This may not immediately print the tightest group but should have the best SD/ES. The group can be tuned later with seating depth adjustments when you get back.
Once you have that decided, load enough to Chrono 5 and have enough leftover for zeroing the rifle and then hunting with.
When you get back and have more time, thats when you focus on fine tuning for seating depth and ultimate accuracy. Don't try and get it all done in limited time, you'll rush and be unhappy with the results.
