300 RUM...off the shelf amo?

[AyeFish]

A lot of the off the shelf 300 RUMS have limited magazine length. I have one in Savage that's shooting real nice with my hand loads.

What about off the shelf-amo? Specifically I'd like to try out the 180 gr Barnes tsx Federal.

Also the Remington Swift Siracco.

Anyone know if these are too long to fit in a base model 300 RUM magazine?

I'd like to know before dropping $ on it the amo.

factory ammo will fit all factory rifles chambered for it with safe pressures. that is the whole point of sami standardization
