7mm IHMSA cast bullet loads???

[marshall623]

Thanks for the info. Now if I could just find some 4759 or 5744, I could start working on a load. Since this round is built off the 300 savage case, could one also look at some of the powders listed for use under the 300 savage cast bullet loads?

I've been shooting RL 7 in my 7-08 Striker under a Lyman 287641 ( 160 Sil. ) I got lucky my mold drops with the noses right on .277 I've had good results with RL 7 and it meters like sand . I also agree with Charlie the more cast I shoot the more I seem to be leaning toward the slower powders ( one listed for jacketed data ). I have to tweek the RL 7 loads a little and then next on the list is 4064 using Lee's reduced powder charge formula .

I bought a Wichita in 7mm ihmsa about 2 months ago and agree with the above about imr 4895 being good for reduced loads. I do not use cast bullets but, am using the speer 7mm 110 tnt bullet with 31 grains imr 4895 and it shoots very accurate and is a very mild load. The manuals show going up to 38.5 grains with this bullet weight so this is about 30% reduced.
