In shooting my 30-06, I've noticed that the 150 gr. and 165 gr. Remington Core-Lokt PSPsboth group well. As far as I can tell, there is no difference between the 2 in terms of accuracy. Which one would be a better choice for whitetails and why?

Also, they are both the same price...

Both kill deer well. I like passthrus and the heavier bullets are slightly better at making exit holes.....go with the 165.

I know a number of guys who use 150 gr, equally just as many that use up to 180gr for whitetails, it boils down to accuracy and situation why they choose what they do. Obviously accuracy is moot, so I would then ask yourself what the situation is and pick the appropriate bullet accordingly. ie: If your shots are likely to stretch out 200 or further and/or aim for the boiler room (ribs) then 150 might be better due to it's slightly flatter trajectory. However if you don't expect to shoot longer ranges or most likely 100 yardsor so and/or may take a through bone shot the 165 maybe a better fit.

Either will get it done on whitetail if the guy squeezing the trigger does his!

Well, take your pick if there is no difference in accuracy. Both of course would do well when Deer is considered.

There are people who wouldactually consider using a.223 REM. when hunting Deer. You will do fine with either bullet weight.

I have killed deer with 150, 165, and 180....take your pick. Either way ol Bambi wont ever know what hit him cept the ground. Id go with whatever grouped best.

I'm with the majority. Take your pick. The deer will never notice the difference. The 150 is probably moving slightly faster but the 165 more than likely has a bit heavier jacket for a more controlled expansion on heavier game like bear or elk and you will more than likely get better penetration with the 165 on a quartering shot. Broadside, both should pass through but the 150 will probably open up more causing a larger wound channel.

I'd go with the 150's on whitetail. You should still get pass throughs. Shooting 165 Nosler partitions in my 06 it seemed like they didn't open up much at all. I just think that on whitetails the 150 is all you need and you'll get a bit more velocity and flatter trajectory

--------------------------------
Make your first shot count!

You will find the trajectories of the 150 and 165 to be nearly identical due to the BC of the 165 being higher than the 150. The 165 will also buck the wind much better on a long shot. So you have equal trajectory, less wind drift, and better penetration with the 165. I say 165.

I preferthe 165's but both do the job
