Losing my groove

[DMY]

I was very pleased to receive some 200 gr SWC -groove less bullets in .452 Dia within 5 days of ordering. They are basically a H&G 68 profile, except no groove. I've had good success with a similar, grooved bullet froM the same manufacturer for my 625s. Any input whetherv the velocity should be higher or lower?

All depends on how much powder (and type of powder) you put under the bullets .

Are these plated bullets, coated, waxed - what? It’s difficult to give an informed answer without knowing more…

These are Hi-Tek coated, non-grooved, SWC. My typical load is 4.2 grs of Bullseye, Federal LPP, seated to a COAL of 1.250", taper crimp, and fired out of a 5", 4", or 3" N-frame.

Treat them like a regular cast bullet. I have heard they can be pushed 100-200 fps faster, but in my experience with hi-tek bullets that made a mess in my barrel, coating came off and was a royal aim to clean. 125g 9mm brazos at 1200fps. They do fine at about 1000fps for me.
