270wsm

Hello all! I don't know if I'm not searching right. I can't seem to get find what I'm looking
For. I have rem 700 in 270wsm. Since powder and bullets are hard to find. I found a box of sst and interbonds. If I work up a load for sst will interbonds be ruffly the same powder charge? There 150 grain I'll be using retumbo. Thank you

It'll be somewhat close if the bullets are a similar shape (I don't know if they are). There are a lot of factors in play that can cause variations in optimum charges.
In my experiences bullets of the same weight, same construction, roughly same shape, similar ballistic coefficients, and with roughly the same bearing surface will have very similar optimum loads.

Thank you! I would start a few grains lower.
