I went with the 139's instead of a heavier bullet because I don't think it takes much to kill 100 lb deer. Most deer are killed within 100 yards. Even 200 is a long shot in the southern US. If I had a 223, I would be confident using that.
I have a Lyman book and only a 140 grain Nosler Soft Point is listed. My Hodgdon magazine is showing COL of 3.25 in and a range of 61 to 64 gr of h4831 also for a Nosler 140 gr partition.
The Hodgdon magazine is showing a 139 gr GMAX bullet of COL 3.29 and H4831 64.5 to 68.5 grains.
I figured the Interlock bullet would be closer to the Nosler bullet because both are lead core bullets and the GMAX is copper.
Go to Cabelas and order a Laodbook USA. They are on sale for $3.99. These things are awesome. Order one for your caliber and it gives copies of load data from all the manuals.
