Best of luck.
About 12-14 years ago bought me a Savage 10ML-II stainless laminated stocked smokeless capable ML.
Sent it to a Smith who's name escapes me to have the action glass bedded muzzle crowned and a third action screw installed to allow removing the bolt without affecting the rifles POA/POI and the barrel smoothed out.
Absolutely love it. Only shot it to 300 yards but it shoots 1-1.5 MOA at 300 and MOA at under 300.
Shoots 250 grain all copper T-MZ's at 2650 FPS/MV and 290grn T-MZ's at 2450 FPS/MZ.
Love the Barnes and Hornady all copper bullets as you can not shoot them fast enough to cause them to fail.
Hornady all copper 250 grain .458" bullets are my favorite and give me the most consistent shot to shot accuracy.
Best Sabots I have ever used are the ones made by Harvester specifically made for smokeless ML's.
