Home Forums Reloading Big Game Rifles Need .260 AI load data

Not the easiest cartridge in the world to find load data for. To complicate the situation, this is for a 14" pistol barrel so any load data with faster burning powder would be much appreciated.

I will be loading 120gr Nosler BT but any data with faster powders is much appreciate.

Thank you,

Richard

Richard, regardless of it being a pistol or rifle, the load data should be the same, the difference would be in your achieved velocity.

You should use standard max loads for 260rem data as a starting point, and expect your max load for a given powder to be 5% above the max load listed for the 260rem.

In regards to faster powders, either of the 4895 varieties should be a good option.

you ought to find something in here that will suit your needs...

That is for the 120 grain bullet weight. If you are trying to keep recoil down... use the 3031, RL 7 or IMR 4198 load data...

These are for a regular 260, but the AI only adds a couple of grains more if you want it.

I've been shooting the 260 since 1998 when it came out.

When did Steve's pages come back up again. Been a while.

I would add check your case capacity with a 120 and water. Then look in Nosler data if your capacity is the same as 6.5x284 that would be about max

Good luck and shoot straight y'all

After Steve passed evidently his nephew took it over and has been running it. Its my main source of load data since its so easy to bring up and has most of everything I'd ever need... easier than looking thru the dozen or more reload manuals I've gathered over the years. I've been using it for years, even right after Steve passed... so a long time.

^ ^ This, as far as load data goes. ^ ^

Fastest powder I've used in my .260 rifle (120 - 123 gr bullet) is Varget - and it does very well. 4064 should fare well with 120's

Thank you fellas for all the help!

You're only off by 17.5%

Per Nosler:

260 Rem (reg) + 120 bullet => 47.8 gr H20
260 AI is 5% bigger, so => 50.2 gr H2O

6.5-284 + 120 gr => 59.0 gr H2O

but thanks for playing the game . . .
