Would like to obtain some starter loads for the .416 Rigby using Hornady 400 grain Interlocs and IMR 4831 with Federal GM215M primers

To be used in my Ruger 77

RaisedIN,
Welcome to the forums. Saeed has been kind enough to post load data that he has collected.

Best loads are with Rl-22. Try 98-100 grs.2450fps and 1 hole groups at 100 yrds.-Rob

raisedin99,

The following are some of the starting powders and charges I used in working up loads for my Ruger M77 .416 Rigby using the Barnes 400 gr. XLC’s. Maybe they will help you. Lawdog

H4831 99 2430
IMR-7828 101 2374
IMR-4831 91 2375

Thanks for the information guys.

I have a Ruger 77 RSM in 416 Rigby, the old model with the heavy barrel.

I am using the same components you listed with one exception the H-4831 is old surplus.

I am using 103 grains to produce groups of .585 with beautiful clover leafs.

It is a lot of rifle for the money.
