Re: Loading to a prescribed recipe with new components
Remember the adage about 'give one a fish and feed him for a day, teach him to fish and feed him for life'? You already mention you are thinking about getting into reloading. All the effort you put into guiding another to develop loads for you can be channeled into you learning to reload.
The 30-06 is straight forward with lots of data and an assortment of components. I wouldn't start off worrying about 500 yard shots, just mid pressure, reliable reloads. Yes it may take you a while to assemble proper tools and components, very doable though.
The very 1st step could be some reading, 'The ABC's of Reloading' or a big name reloading manual like Sierra. Summer is almost here, the perfect time.
To your original question, yes you could almost duplicate a load from someone else. There can be a handful of small techniques that can vary between loaders though. You could get rather close to the original load. Just to back up, precise shooting at longer ranges requires the 'total package', quality ammo is only one part of that total package.
