What were the groups with H4350?

Does it make sense that my 79 DRT is hitting min terminal velocity essentially at the same distance as my 95DRT in 6CM?

.223 with 79 DRT (using 1400 per web)



6CM with 95 DRT (using 1600, per web)

That doesn't really surprise me. Were you thinking the 95 would get you further?

I was. Kind of thought “a 95 out of 6CM outta outdo a 79 from a 223” … guess I was wrong.

Yeah that 95 is not very slippery.

The BC on the 79 is .425 and the 95 is .360. that could be making some difference.

Has anyone loaded or used their new 7mm bullets? Looks like there's a 140 and 165gr. .510 and .601 BC.
Seems like those are good weights from 7-08 to 7RM/PRC.

I wish I could buy some more of the 152gr 277s.

DRT, finally shipping to California residences, last time I tried was a year ago and they refused to ship to CA. That appears to be resolved, now.
