Need Help With Tracer Load --
Recently I was given several 1000 pulled M62 .308 tracer tips. After weighing several, they all seem to be in the 140gr range. My concern is actually the length of the tips and the possibility of seating them too deep as to compress a powder charge. They are rather long as compared to the M80 tips. Anyone out there have any experience reloading the M62s for the M1A? If so, would you mind sharing some loading data. They will be shot in the M1A Scout and bolt gun. Thanks in advance for any assistance you may be able to render!!

The real diffrence in the m25 and the m62 is;
m25 tracer 30.06- (or early versions t10) has a 145 gr bullet with 50 gr of IMR 4895 powder and travels 2665 fps. The tracer compound contains compostion R 321 which is 16% polyvinyle chloride, 26% magnesium powder, 52% strontium nitrate.
m62 tracer 7.62x51- has a 142 gr bullet with 46 gr WC 846 powder and travels 2750 fps. The tracer compound contains compostion R 284 which is 17% polyvinyle chloride, 28% magnesium powder, and 55% strontium nitrate. (Also used on m196 .223)
and just to throw in;
m276 dim tracer compound is compostion R 440 which is barium perioxide, strontium perioxide, calcium resonate, and magnesium carbonate.

You do know that these items burn inside the barrel...
and an extremely abrasive residue is left.
Are your group holding tight???
