260Rem, 123gr SMKs, H-335?

[Walt Schmidlin]

I am running low on IMR 4064 which I use successfully with 123gr SMKs but not surprisingly am not the only person I’m sure.
However I do have H-335. I have found H-335 loads in the Sierra manual for 7x08 & 308W but nothing for the 260Rem. Hodgdon’s on line load data doesn’t list anything for 123s & H-335 either.
Does anyone have any online published data for H-335 and 123s in a 260Rem? Only looking for 2500-2600fps, shooting paper at 300yds max.
I know H-4350, H-4831SC, RL-17 and I’m sure other powders work well but I have H-335
Thanks in advance.

36.7 gr for 120 grain bullet load in a buddys 260 shot ragged holes not sure of velocity but i do know when he was loading max it was way unpredictable with temp . I personally use varget for that weight class bullet but you only have h335 good luck

start at 35.0 of 335 and work up or start at 34 grs and work up

 

[Walt Schmidlin]

Appreciate the suggestions, I think I’ll be conservative and start at 35.0grs. Really like the way H-335 meters.
Thanks again..

Keep an eye out on PV for the 4064, I’ve seen it off and on recently. I picked up a couple pounds a while back. My 260 shots the 100gn Sierra hp ver well w 4064

What is the barrel length and COAL of your load?

 

[Walt Schmidlin]

What is the barrel length and COAL of your load?

2.880+/- OAL, 30” barrel

 

[Beiruty]

2.880+/- OAL, 30” barrel

Very fast powder, 3040 fps, 81% fill ratio at max 40.5gr of H335

 

[Beiruty]

At 33.3 gr of H335, MV is 2620 or so, the case fill ratio is just 66.6%

I believe I’ve seen Accurate 4064 for sale. I’d go with that.

I’ve been reloading 260 for some time. I would not load 123s with h335.
sierras 120 or 123 best MV I’ve found to be 2750-2800fps- consistently extremely accurate.
