Sizing Moly Coated Wadcutters?
In a long quest for a readily available hard hitting hunting pellet for my .357 Windy City, I’ve ended up with a case of .357 hard cast, moly coated wadcutter projectiles. These are very accurate but the friction from the large bearing surface really hampers velocity (and makes them quite hard to chamber).
I’ve now got a .356 Lee sizing die to cure the issues of friction and chambering.
Bullet sizing is new ground for me. I used to mold my own .44cal wadcutters for my S&W years ago, but just loaded them straight from the mold. Likewise, my .360 cal round ball is used as it come from the mold.
The instructions for the resizer state NOT to size unlubed bullets as they will lead the die.
I’m not sure if this is true with hard cast & coated bullets though.
Anyone tried sizing moly coated bullets without lube?
I don’t want to ruin my die and don’t want to be shooting pullets coated in Alox through my nice accurate barrel if I don’t need to.

Diddo on what Jerry said. I have sized thousands of mly coated bullets with no trouble, and those hard cast bullets are far from ideal, you loose power and they are hard to chamer and are not the most acurate choiice for a air gun.
BTW was your S&W one of the old breaktop New model #3’s?

Well, if the bullets are moly coated, they are lubed already, correct?
That said, buy a little tin of sizing wax from Midway and brush it into the die every dozen bullets or so and all will be well.
Of course, you’ll still be dancing around the issue of proper bullets for your gun. Hard cast can work but is rarely, if ever, the best choice for an airgun.

Surprisingly enough, the ones I shot unsized are giving OK groups of 1″ at 40 yards. Just sizing them to get them leaving the muzzle a little quicker and cut down the wear and tear on the bolt probe.
The Smith was a 629 with a 10 5/8″ barrel. Used it for metal silhouette and the odd razorback.
