Handloads for a rifle, safe to use in another rifle? June 15, 2021, 11:21:10 AM I owned a Howa mini-action bolt rifle chambered for 6.5 Grendel years ago which I developed a load for. The only thing I'd wished for with that rifle is for the muzzle to be threaded, but that was not an offering at the time. I sent the barreled action off and had the muzzle threaded; the rifle never shot accurately for me after that. Rather than wasting time and resources trying to figure it out, I replaced it with an identical, new Howa barreled action that was factory threaded for a muzzle device, I am just now getting around to pulling it out of the safe and shooting the darn thing.I have a couple hundred handloaded rounds from the first rifle made before I sent it off for threading, these are loaded 0.2 grains higher than the maximum shown in the Hornady reloading manual for a 120gr class bullet and Varget powder. This load shot real good in the first rifle.Once the new rifle is broken in with some factory fodder, do I shoot these handloads, or pull them apart and reclaim the components? My instinct tells me to recycle the ammo, especially since the charge is slightly above the reloading manual maximum.Thanks.
