Powder for 260 Rem. and 6.5 x 55 mm

[350tracker]

Would anyone have experience in reloading both of these cartridges and give me info on which powders work well for both. The main purpose of these rifles will be for deer hunting so I’m looking at bullets in the range of 120 gr to 140 gr. I will be starting load development and would like to keep my powder stock down to a minimum as for choice but more of the same powder. Thanks for any info...

Hi, I have a Tikka in .260 and shoot mostly 140's. My goto powder as well as a number of guys I know is H4350. I also had good luck with RL-19, and H4831. With a 120gr bullets RL-15 was good too. The bullets I was using were 140gr Bergers, 140gr A-max and 120 TTSX.
Have fun.

4831 either brand

I have used RL17, H4350, IMR 4350 and H4831SC in my .260

Varget can also be used.

Thanks, This gives me a good idea where to start...

I've used H4350 and H4831 in both the .260 and the 6.5x55

Reloder 22 is reputed to be an excellent powder for 140's.

My limited experience with the 6.5 x 55 and 140's supports this.

Out of all the powders mentioned which would be best to be used in different seasons or not being temperature sensitive ?

 

[Swiend]

Hodgdon H414 Works great, not temperature sensitive but works best with magnum primers.

In my 260 I use H4350 behind a 139 scenar.

I use H414 with 120 TSX in my .260

4831 either brand

Have both,

Best: R17, H4350

Good: R19, R22, IMR 4831, AA3100

Bad: None yet, can't get the things to shoot squirrelly

Also tried VV N-560. Very accurate, however using book loads the velocity was 100-150fps slower than then R17, 4350's range.

Most loads were with Hornady 140grn SST
