Thread: Ogive variance between batches (Sierra TGK .270)

I have one packet of Sierra bullets 140gr in .270 which came with the rifle I picked up off TardMe. I recently bought a second packet. There was a difference of up to 0.024” in measuring to the ogive between packets.

The newer box was all the same ogive measurement, and the overall length within 0.002” of each other.
The older box had a difference (compared to the newer box) of between -0.019’ and -0.024” for the ogive measurement, yet the overall length within 0.005” (including with the newer box).
Both packets had a consistent .277 diameter.

So even though the lengths were similar, and acceptable. And, of course, it’s expected to have differences between batches. This caught my eye as a rather unexpected jump in measurements.

I am new to this. I guess this is why people say not to mix your batches
