Looking for .257 Roberts Loads

[dcon]

I just bought a browning bbr in .257 Roberts and would like to know some of the loads you guys have had good luck with. Any load suggestions you guys have would be great, but I would really appreciate any using 100gr partitions.

What bullet?
My attitude would be 75 gr Vmax for rodents and 100 gr for ruminants.
The Sierra load book has loads that I wind up using after tying lots of my own concoctions.

I've been loading 257 Bob for my mother-in-law for many years, she hunts with a Griffin & Howe 257.
My load is 42gr of IMR4895 under Sierra/Speer/Hornady 87gr bullets - very accurate. Max load for that rifle, you might want to start at 40gr.

i haven't wrapped up my development yet, but am seeing some promise coming from ramshot hunter and 100 grain hornadys.
