Hey, Got the Hornady Premium powder funnel kit. Very happy with it so far. Talked to Hornady and Area 419 and found that they both use a 5/8x24 thread pitch. Went out on a limb and ordered the 419 pistol adapter and it fits perfectly. Area 419 also makes some different sized rifle heads and modular 3in drop tube sections. Really been happy with the Hornady funnel kit, and now I can add on a couple extras to make it even better!
