H&N Baracuda Match pellets

IT is an indication that different dies were used. Sadly, size may actually be very similar. I can rarely feel a difference in seating pressure between them, but one "size" is often better in one gun, and you really need to give both a try. In some guns, I can find no difference in groups.

At one time, they actually offered sizes from 5.50 to 5.55. My guess is that was too much of a range, so it was narrowed down to the two diameters that you mentioned (most popular?).

Many/most barrels seem to prefer something in the 5.52mm range, although if you measured the entire tin, not all would actually BE 5.52mm from my experience. Most seem to run larger than stated on the label.

I like the .22 caliber, 21.14gr, H&N Baracuda Match Pellets, they work well in 5.52mm, but again, the bulk are likely closer to 5.53-5.54mm.

If you choose to do so, you can run a large pellet through your barrel and measure to see the approximate diameter of that particular barrel and know about which one to buy.

I usually simply lightly tap a 'standard' pellet with a hammer to bulge it out a tad, lube it slightly, then push it through the barrel with a coated rod. If your barrel is choked, then you don't want to push it completely through as the choke will make it much smaller than the rest of the barrel. So, stop before the choke and push it back to the breech.

I agree the listed head size is smaller than what my head size gauge says. But the 5.51 run smaller than the 5.52 but there is overlap. They are my P35-22's favorite but it shoots both head sizes as accurately. This year my best 30 yard challenge score with this gun, a 198, was equaled by the 21 grain Baracudas. The one 200 I've shot with that gun was with the Match, however.
