The AVS approach

Accuracy starts with
the right diameter.

The key to shooting slugs accurately is matching the slug's diameter to your barrel's groove diameter — not the bore — then choosing a weight and length that your twist rate can stabilize.

01 — MEASURE

Slug your barrel

Push a soft lead slug through your barrel and measure it with a micrometer to find the true groove diameter. Barrels vary — even within the same model.

02 — MATCH

Pick a diameter

Choose the AVS diameter that matches your groove, or a half-thou over. With 22 diameters on offer, there's almost always an exact fit.

03 — TUNE

Dial in weight & base

Match grain weight and base style to your gun's power and twist rate. Not sure? Start with a 3-base sample pack and let the target decide.

Also available in ELR Round Nose. Tap any diameter to shop it.

The new ELR Round Nose line.

Our extreme-long-range profile: a rounded ogive and Dimple Boat Tail option for a higher BC, flatter trajectory and better wind-bucking at 100 yards and beyond.

AVS slug base choices: boat tail, cup, dish, hollow cone and flat

Unique base choices

One slug, five ways to stabilize it.

The base changes how a slug seals and stabilizes. Pick the one that suits your gun's power level and twist rate.

DBT

Dimple Boat Tail

Highest BC for long range. Prefers a faster twist rate to stabilize.

CUP

Cup Base

Best for moderate-to-high power PCPs with shorter, lighter slugs.

DSH

Dish Base

Ideal for high-power PCPs; can work at moderate power with faster twist.

FLT

Flat Base

For longer, heavier slugs in very high-power guns matched to twist.
