Description

Lee Collet Neck Sizing Die 300 Win Mag 90961

Only the Lee 300 Win Mag Collet Die uses a Collet to squeeze a Mandrel, resulting in a perfectly aligned case neck with less run out. For a flawless bullet fit with minimal run-out, a collet squeezes the case neck against a precise mandrel. It only sizes the neck and doesn't require any lubrication. Collet-style decapper clamp keeps the simple X expander
firmly centered in the die while allowing the decapper to move up without breaking if an obstruction is encountered.

Features:

➼ No lubrication required
➼ Guaranteed accuracy
➼ Extends case life 10x
➼ Fastest to use
➼ No cleaning or lubing required
➼ Sturdy shank so strong you can drive out a stuck case without damage.
➼ Long guided neck expansion area located to begin expanding as soon as the neck leaves the die at the presses maximum position.
➼ Tapered area expands sub calibers when case forming, quickly and effortlessly reforms dented or squashed necks.
➼ Super strong integral decapper is almost unbreakable.

FAQs

1. Do I need case lube?

No. One of its biggest advantages is no lubrication required, making it cleaner and faster.

2. Will it improve accuracy?

Yes—collet dies are designed to reduce runout and improve bullet alignment, which helps tighten groups.

3. Can I use it for all my brass?

Only for brass fired in the same rifle. Otherwise, chambering issues may occur.

4. Do I still need a full-length die?

Yes. You’ll occasionally need a full-length resize after several firings to maintain easy chambering.
