if i reload a 150gr sp bullet in my 30-06 will it be the same as a 150gr btsp???? i got in an argument with a friend and he says that a regular sp will have the same trajectory and point of impact as the same weight btsp....but the boat tail had a larger tail with more weight in it for hunting which will change its flight path wont it?????

At short range you would probably not notice a difference however at longer ranges the bullet with the greater ballistic coefficient will get the nod as far as trajectory goes. "A bullet with a high BC will travel farther than one with a low BC since it will retain its velocity better as it flies downrange from the muzzle, will resist the wind better, and will “shoot flatter”
The BTSP is a far better choice for long range however the flat based bullets will work just fine for most deer hunting. I would consider the hornady sst for an all around versatile bullet. It will give you a lot better ballistic coefficient and sectional density and hold up to wind drift better. The boattail design also carries momentum and therefore energy better and has an overall flatter trajectory due to the low drag design. As a handloader having the option to load bt I always try to go that route.
"the boat tail had a larger tail with more weight in it for hunting"
He just made that up. Or he misunderstood an advertisement.
The boat tail (in the same weight and caliber) will generally have the better BC, thus a flatter trajectory. As far as point of impact at 100 yards or so, you have to shoot them to know for sure.

For a hunting bullet?
I'd chose the flat base, unless it is a bonded core or other premium bullet.
The BT is like a taper chuck drill bit in a drill press.
Once the core slips .001" in the BT jacket, it is loose & coming out.

Here's a little piece of advice from one handloader to another. Buy a bunch of different types of hunting bullets, powder, and primers and mix and match. Once you have found the most accurate load that shows no signs of excess pressure, stick with it.
Boat Tail bullets have a higher ballistic coefficient as the design reduces drag so they shoot flatter. At short range this will not be too noticable, perhaps a couple inches difference but at longer ranges +300 yds this difference becomes more noticalby significant. Look in your manual and compare ballistic coefficients and compare the ballistic charts for bullet drop at various range.
well is what my deal was is i have 100 interbond 150gr sp that i got when i bought my press.....i bought 150gr btsp....i was setting the press up with the interbonds as they were free and didnt really like them as a hunting load compared to the btsp......so i was wondering if i dial my scope in with one would it be on with the other.....because i didnt think they would be being different construction and design.......but my friend was trying to tell me (as he handloads) that 150gr bullet is still 150gr bullet no matter what you do with it...and i was telling him he is wrong........and yes i would like to use the sst for hunting but i have 200 rds i need to get shot up

At all sensible hunting ranges, you won't tell any difference in trajectory.
There may be a difference out at extreme ranges, but I'm not good enough to notice, and I would wager that most aren't. There are always exceptions.

Not your caliber but with my 5.56 there is less than 1/4 group difference favoring the BT at 200 yards (2" vs 2.25). Same day same wind, bench etc. slow fire 5 rounds.
IMO load them the same and either should work for you with little or no difference shorter than 300 yards.
