How to modify reloading data when using SRP's instead of LRP's?

[dukecola]

I just got some Barnes 145g Matchburners. Barnes 6.5CM load data is for LRP's and I want to use SRP cases. I asked Barnes for a SRP load and they just said they only have publish data for LRPs. How can I develop a safe starting load by modifying the LRP load data? This is the LRP load data, H4350 Min 37.6, 2474fps, Max 42.1, 2727fps. Are there any other 145g bullets from other manufacturers where I could use their load for the Matchburners? Thanks.

Just use the LRP data, you'll be fine.
