Re: Load Development Confusion
<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: AR-10 Shooter</div><div class="ubbcode-body">I've worked-up several loads for the 700 and AR-10. They are very accurate at 100 yards for factory guns and I'm happy. My current load for the 700 is 43.3 Varget under a 175 SMK. However when I read suggested loads on the forum, people are loading 45-46 Varget. </div></div>
You must consider the M700 a different animal for reloading purposes than the AR-10. The AR-10 will end up being reloaded to suit the gas system, while the M700 will be loaded to suit the higher pressure accuracy node.
If you load the AR-10 cartriges with too much powder or too slow a powder, you will overdrive the gas system and the ejextion will not time as desired. When you do find the powder and charge weight the gun likes, the brass will drop over your sholder in a nice neat pile. It is likely that you will find an accuracy node around 43.5-44gr of Varget, here. You will be using more neck tension to insure no bullet setback while in the magazine and no bullet ram forward as it is chambered. 0.003 neck tension is recommended.
For the M700 different rules aply, since you are not loading in order to cycle the auto-load cycle, you are loading strictly for accuracy. Here, you can play seating games (and OAL games) with the bullet, and push the edge of sane pressures. Sticking with the 175 SMKs, you should find an accuarcy node around 44-44.5g Varget. For ammo that suffers no abuse from the reloading station to the final firing position neck tension as low os 0.001 is allowed. Tactical ammo should be loaded to 0.002 neck tension.
For maximum accuracy in both guns develop different recipies for both guns and keep the ammo segregated.
