Nuke feed question

[Keith]

Sorry for the long delay…

I run 124 gr JHP’s (nukes and the previous MPR’s) with 5.4 gr. Silhouette, at 1.075″ and it gives me consistent chrono readings of 1050-1075 fps in my 4 and 4.25″ barrels.

I could run them longer as some have mentioned, but this works in every gun I’ve ever loaded for and is a very soft shooting and controllable load. Yes pressure increases as OAL decreases but 1.075″ fits most book data for 124 gr. JHP’s and isn’t considered “short.”

I bought a throat reamer for the Springfield, and did it myself. I got my OAL to 1.120 with the nukes, and 1.100 with the 147 Match winner FP’s.

The Glock gen 5 I thought about reaming but it seemed to “break in” after 2000rds and I am able to seat longer now.

A KKM barrel my have a tighter chamber also due to them being more accurate barrels. Not sure though.

Sorry to answer so late.
