Thread: Load accuracy, 24" barrel to 18" suppressed.

No doubt this question's been asked and answered. Had a look could't find. Hence:

I have a Ruger M77 Mk1 7 x 57 with a 24" Shilen barrel. Three distinct loads group (3 shot) under MOA. The rifle doesn't see any action because it's parked next to a shorty suppressed .308.
Seriously considering chopping the 7x57 24" to 18" and suppressing. Question: Can I expect the loads developed with the 24" to perform simarlarly with the barrel shortened to 18", excepting velocity? Don't want to start from scratch and would love to start the rifle walking again.

Cheers
