If you hunted white tail deer only and could only use one load for ever & ever, what would it be? Remember only one load.

48 grs IMR 4350 powder. 87gr Sierra bullets. Varment's and Deer. I have used this for 43 yrs. Understand this might not work for you, all guns shoot different. Carl L.

35.0 grains of IMR 4064 behind the Sierra 117 grain SPBT.

Not too hot but it sure shoots well in my rifle.

I use the SPEER 100 grain spitzer over 45 grains of IMR 4350 powder, seated out as long as will function in my BLRs magazine. I tried several of the 120 grain loads but they tended to seat the bullets very deeply into the case and the velocity was lower than I expected, and acuracy was very inconsistant, which if found surprizing because the 117 grain round nose bullets by HORNADY and NOSLER 115 grain spitzer partition bullets did much better. of all my loads the nosler partition 115 grain over 43 grains of IMR 4831 proved to work best on large mule deer but I use the 100 grain SPEER bullets far more often as they are much cheaper, and slightly more accurate. since I only use the 257 rbrts BLR on deer the differance in penetration is of no practical importance

100gr Hornady (passes thru most times) and 46gr IMR4350 (worked up).
