Looking at the Sporter manual it looks like it will handle up to 1" diameter barrel.

Cant stand it because it changes point of impact..it is reliable for accurate speeds

You are not supposed to zero with it on. I don't care if it changes POI. It won't change group size. Use it for its intended purpose, velocity readings. Once you find a load with the velocity and grouping you like then zero without it.

Yes it will be fine. It does not do well with smaller contour barrels. I have a Rem700 mountain rifle that I cannot keep it tight on. But with some adjustments between shots it does ok. Magneto speed chrono's are great all around.

I agree, it can slightly change poi but it doesnt seem to affect the size of the group for me. Which is surprising since I thought it would change the harmonics but it diesnt seem to do so on my rifles.

Now there's a fella who knows how to use his equipment. Well put, Hoyt.
