I'm looking reload 260 Remington what bullet do I need
I know it 26 cal but what bullet
264 dia
Or 6.5 bullet
Thanks
Some guns like different bullets. The perimeters people are spouting out are not scientific fact. I wouldn't go super light our super heavy. I'd pick for purpose!
While a .264" bullet is the proper size for 260 Remington and most other 6.5mm cartridges, .264" is not 6.5mm. .256" is 6.5mm. 6.5mm refers to the land diameter, but the bullet is sized based on the groove diameter. In my experience this is where the confusion about bullet size usually comes from..264 is 6.5.
When I ordered my Shilen 260 barrel the 1-9 was recommended for lighter bullets, 120-130 grains. I had 120's so I bought the 1-9 and have been very happy with it and see no need to go heavier for deer.With 1:9 twist you will have to figure out what is the highest bullet weight you can stabilize. Likely 130 and under possible even 130s won't work well.
My savage 260 is 1:8 twist and shoots 130s extremely well. Never tried 140s because I like the speed/weight combo of 130s.
