Home Forums Reloading Big Game Rifles 270 Win, Re 26, 150 NPT - who needs a 7 mag?

Yes but we all know the pressure(and velocity) varies a lot from rifle to rifle and manual data frequently does not hold up in our garden variety rifles. We see that a lot and it has always been common.

I don't have any doubt RL26 is a great powder since it seems to be a temp sensitive rendition of RL25 which I've been using for years now in the 7 Rem Mag,and got some pretty giddy 270 velocities with as well about 10 years ago..... Like 3200 from 22" barrel with 130 gr bullets.

Oh....and BTW I have also seen a couple of pre 64 M70 270's with 24" factory barrel give over 3200 fps with 130 gr bullets,with no outward signs of excessive pressures using H414.

So, yes, I believe 26 will give those velocities; but when I see cases like the 270 (65 gr ? of capacity) giving about the same velocities as a 7mm WSM ( 74 gr of capacity,....giving about the same velocities as an STW and more than a 7 Rem Mag with 80 + gr of capacity........my antenna goes straight up. Not that I doubt it....just that it leads to more questions in my mind.

Followed to its dryly illogical conclusion,we can start to assume that RL26 erases all substantive difference between a 270 and 7 Rem Mag....which is, of course, ridiculous. Anyone with enough experience with both knows this.

I never saw the sense in chasing another 50-100 fps from a smaller case when that same velocity was easily achieved from a commonly available bigger case.

Based on what I see here with some of the velocities, it won't be long before the primer popping starts.
