[Michael C. Smith]

Was thinking of trying imr 4451 with the 140 nosler bt. Has any one tried this combo?

6.5 creedmoor
Hornady brass 52.5 h2o
Fed 210
140 nosler bt
Coal 2.825
Rem 700
26 inch barrel
If someone could run a quick load for me would be great so I will know where to start

Thank you Michael
