These Hornady ELD Match Rifle Bullets, 6.5mm, .264, 140 Grain bullets could potentially be used for hand loading .260 Remington. However, this depends on what reloading manual or specifications you are following. These 140 grain bullets may be "too heavy" for loading in 260 Remington. I recommend contacting Hornady to see if they recommend using the Hornady ELD Match Rifle Bullets, 6.5mm, .264, 140 Grain bullets for 260 Remington or if they have a recommendation for a better suited bullet.
