Well Strut, that's what I used. 3 different loads of IMR 4350 and 100gr Sierra SPBT's. Thanks for all the input guys!

Oughta be a great working load for you.

I use the same bullet very nasty excellant fragmintation. I took a cow elk 2 years ago at 450 yards 1 shot did a great job.

i also agree imr 4350 is a great place to start. im currently running RL 19 with 85 grain nosler varmint ballistic tips. getting about 3350 FPS. i could load it hotter but i get excellent .5" groups at 100.

Went to the range yesterday with 3 different loadings of IMR 4350 and 100gr sierra's. Best accuracy with 52.5gr of powder, 1/2" 3 shot group. Guess that's what I'll go with.

Always quit when yer ahead.

im still workin on the 280! tried some h4350 the first day...might have a load that shoots out of my 7 test charges..going to reshoot one of the charges...need a break in the weather this week to test H4831 charges...

really like the caliber..ive never shot one but always liked the ballistics of it and wanted one...recoil is nice and the hotter loads are comin outta there pretty dang fast...

looks like another few days till the wind dies down and i can get back to it..
