Advice needed to start my reloading addictin

[thermaler]

Today I stopped and bought a box of Sierra 150 gr spt hunter pro. I had better results with getting the same OAL length at 2.800 when loading them, I loaded 5 different sets of 42.3gr, 42.8gr, 43.2gr, 43.7gr, and 44.2gr. And set Hoping to get some type of decent results tomorrow. Wish me luck.

Hmmmm...I'm going out on a limb here and venturing a few opinions that others may or may not agree with. It sounds to me like you are not measuring the specific bullet to your chamber--rather you are simply going by SAAMI spec for the over-all cartridge length (COL or COAL) as opposed to seating the bullet to the part of the bullet where the curve begins--otherwise known as measuring Cartridge Base To Ogive (CBTO or CBO).

You're starting off with a bullet design closer to a "flat-base" design (not as ballistically efficient as say the matchking or even gameking). I'm sure you'll get adequate results for taking deer--but don't be frustrated if you don't get spectacular one-hole groupings. On the other hand who knows--you may get lucky and prove me wrong . : )
