I have the same rifle, and it's very easy to develop loads for it that duplicate, and better, the performance of any factory match ammo.Just my perspective - if you intend to duplicate modern ammo - that is probably not going to happen - the commercial guys do not use the canister grade powders that you will get - they will blend up a "lot" to their specs - is probable that the primers, brass and bullets that you use may not be the same as they use. When I started, it was relatively easy to do better, accuracy wise, than factory rounds - but now-a-days, it can be a real challenge to just be "as good as" they are. Having said that, I recently acquired a Tikka T3X in 223 Rem that the previous owner had really good luck with factory Hornady Match rounds. So I bought 500 of those Match 75 gr. BTHP Hornady bullets to see if I could make some "as good as" Hornady can - that is yet to be seen - I have not loaded for that rifle yet.
You're right, some of the premium and match ammo available off the shelf, for the reasons you describe, are very hard to duplicate or beat.
I have a set of old Bonanza Bench Rest dies for the 223, as well as the 6.5x55, and Palma Match 7.62x51. They're some of the best I've used, and ammo is always very straight, with less than .003 run out.
Often, hand loaders don't check the run out on their finished ammo.
The last box of match ammo I picked up was very straight. It was all under .003. That's incredible for factory quality control.
