Any one have some reliable load data for these bullets?

You didn't specify a powder but here is some 130 grain data using both H-4831, which is a good choice in the SC (short cut) version and is quite temperature insensitive - and I also listed data for one of my favorite go-to powders for this type of application - Alliant ReLoder 22:

Hornady lists H-4831as a good powder choice. start is 55.5 gr and max is 62.9 gr with the 130 SST at 3200 fps.
I have found Hornady data in their latest edition a bit lower than I experience in real life and lower than other sources.

Nosler lists also lists H-4831sc as a good choice. start is 62.5 gr and max is 66.5 gr at 3239 fps.
RL-22 start is 61.0 gr and max is 65.0 gr at 3396 fps.

Speer lists H-4831sc as well. start is 59.0 and max is 63.0 for 3173 fps.
RL-22 start is 62.0 gr and max is 66.0 gr for 3228 fps.

Hodgdon - H-4831. start 63.0 gr and max is 67.0 gr for 3228 fps.

Alliant - RL-22. start gr (none listed) and max 66.0 gr for 3228 fps.

My experience:

I use the 130gr SST in .270 as my primary deer/mulie hunting load. I usually load for accuracy, not max velocity.

I have tried several powders with the SST: Accurate 4350, IMR 4350, Accurate 3100 and H 4831 & H4831sc. I really wanted to use the 4831, but it was just not as accurate for me as 4350 (both IMR and Accurate).

I used RL19 (and RL22) up until about 15 years ago with Nosler BTs - they both worked great but I didn't try them with the SST. The RL19 & 130 Nosler BT provided fantastic accuracy, but the bullets separated (SSTs are much better). I would try RL19 for the 130gr. SST 270 load first. YRMV.

With 53.5gr of IMR4350, I get about 2875fps, little standard deviation... and .5 inch at 100 yards/ 1.5 inches at 200 yards. Accurate 4350 is almost as "accurate" with a little more velocity with the same load.

Be sure to work up any loads for your rifle...

These seem to be loads for the original .270 Winchester - NOT the new 270 Win SHORT MAGNUM.

Powders and loads for the larger capacity WSM round would be different from its smaller capacity brother of the same caliber.
I think it is quite easy to confuse Win with WSM after the ".270".

Yes... I should have made it very clear... this is my experience with .270, not .270wsm.
