Take a look at these quality leather bags, stitched together in Pennsylvania.
They ship to Canada right quick too.

- Filled mine with washed sand, but since they're 'small', they don't weigh too much.
- Very steady, will yield consistent POA-POI.
- Easy to micro-adjust POI height by sliding stock in bags.
- You can still snuggle up to the gun in whatever position is most comfortable for you - feels natural.
- Rifle glides very well during recoil.
- Compact in the range box.
