[QUOTE="nksmfamjp, post: 1898321, member: 1951"] Single shot: So, traditionally people size throats so that with the bearing surface of the bullet held by the neck and the boa5 tail just in the neck that the bullet just touches the lands. SAAMI Chambers: Typically these are sized so when rounds are seated to mag length, the standard size bullet is about 0.030” - 0.050” off the lands. Mag fed long range rifles: I’ve heard this called by several names, but basically, throats are long like a single shot, but the bullet is seated deep to fit the magazine. When the primer lights the powder, the bullet runs out to the lands, then the powder builds pressure and delivers good accuracy and velocity. I guess my question is do people have rifles setup like this mag fed long throat option? If so, wha5 is the key to making them shoot? neck tension? runout? Neck turn? Certain bullets? Certain powders? [/QUOTE]
