Mine is .22 but what size ?

I bought it for my husband. He says that you need to find out which head size pellet your barrel prefers. It may prefer 5.51, 5.52, or 5.53. He suggests you try pellets in these head sizes to find out which is most accurate with your barrel. Hope that helps.

Will this allow me to shave 4.52 and 4.51 mm pellets down to 4.50 without denting or otherwise compromising the accuracy?

This may compromise accuracy if you size down to 4.50. Far better to to go down to 4.51 so the pellet is a snug fit in the barrel, this is my experience.

Confusing sizes make it easy for me i just need one for a 22pellet

Hi, the .22 sizer is available in 4 sizes (5.50, 5.51, 5.52 & 5.53mm). You need to check which head size pellets you’re are using. If the pellets are just .22 / 5.5mm you probably won’t need a sizer.

Are these very smooth inside, as I had to return a brass version which was very rough as I pushed pellets through?

Hi bought this for my husband. After passing over 1000 pellets through the device, no problems have occurred. It is smooth bore and machined in brass, good for consistent pellet sizing.
