I know the Ken Waters books are popular, and from a few of the other forums I'm on there seems to be loads in certain calibers that are often accurate in more then one rifle. Even though I know every rifle is an entity into itself , maybe a list of pet loads will give others something to strive for or something new to try. AGAIN  safety first and anyone reading this info must back off by 10% and work up!!!

 These are just a few I have worked  up that have had very good hunting accuracy in more then one rifle.
  : in .223. Win brass win SRP  24.3 IMR 8208xbr and a 55 gr Sierra blitz king .  Very accurate in my CZ and a buddy's savage.

  : 22-250 using rem brass WLR.   35 gr Varget and a 55 gr V-max.  Was the third load in the second round of work up for my buddy's tikka great load in that rifle he's knocking off crows at 300 quite often. Under moa with 2 seperate shooters.

 : .243 win varmint load. Win brass Wlr  42.5 RL-15 and the 58 gr v-max.  My favorite coyote medicine currently although I do have some other loads with the 75 gr V-Max for longer pokes. But the 58 gr is great for general  calling and shooting.  Again this load is accurate  in my rifle and my nephews savage.

 : 243 biggame load.   Win brass  WLR  43.7 gr  Hy- brid 100 and a 100 gr Nos PT.  this load has been used in 4 seperate rifles and shoots moa or very close to it in each one. 2 savage youth ( my nephew and my buddy's sons.) in my vanguard and ol reliable a 7600 Remmy ( which is the one just over MOA ).
It has a counted for several deer so far 1 blk bear and my nephew took his cow moose this past fall.

 : 6MM Rem.  Rem Brass Wlr 44 gr Hy-Brid 100 and 100 gr Nos PT . Well this load is very similar to the 243  , this powder and bullet combo seems to be like peas and carrots. My dad and my son both have Remmy 788's  in 6mm Rem . Dads ol rifle shoots this load at moa and he has taken several deer and my BIL used it to take a moose.  Kale ( my son) we just got this rifle a twin to dads 788 I we hope it will duplicate the accuracy of Dads. I have a little time to develop loads as Kale just turned 1 haha. But Granpa snagged him a 788 the day he was born. I think his older sisters may break this rifle in for him.

 : .270 win  Win Brass fed 215 primer  52.5 IMR-4831 and 110 gr Pro hunter.
This was a lighter load developed for my buddy's 15 year old son the first year he hunted , the parameters was a light load for him in his first year of hunting.  I thru this load together out of the Seirra manual I was pleasantly surprised when I put 5 in one hole  at 100 yrds leaning over a bale in my back 40.  My buddy then copied that feat a day later, and his son a rookie shooter had a 3" group his first crack with anything bigger then a 17 hmr.   Then my cousin brought me his x- bolt to load for and just for sh!ts I ran a few of these thru and again  pleasantly surprised.  The next surprise was how this load flat out drops deer 3 deer small sample size but the boys told me they dropped like a rock.

Ill continue more later feel free to add your favorites.

Figured I'd contribute a few.  These are just taken out of my loading records, so check your books as I didn't before posting in case I misstyped or something.  I compare the Hornady, Lyman, Nosler books to start working up a load and always stay within the printed parameters.  As stated, different rifles/bullets will have different results.  Read the "/" as "Or".

Win. 30-30  150gr lead:    32gr Win.748 / 26.5gr IMR3031 / as a light load for a new shooter - 18gr IMR 4198 (very negligible recoil on this load)

.32 Win. Spcl  170gr lead:  27.5gr IMR 3031 / 23gr IMR 4198

.375 Win.  220gr lead:  32.2gr IMR 4198
I've found the win's are more accurate at less than upper loads, in fact +- 1800fps seems to be about right if I remember correctly.

.243 58gr Vmax lead:  40gr IMR 3031 / 47.5gr IMR 4350        100gr lead:  42gr IMR 4831

7mm-08 140gr lead:  43gr Win. 748  (just starting with this one, this is the only load we've tried so far)

.270 130gr lead:  55gr IMR 4831 /  150gr lead:  50gr IMR 4831

30-06 165gr lead:  50gr. IMR 4064  /  150gr lead:  52gr IMR 4064 /  220gr lead:  45gr IMR 4064

300 Winmag 180gr lead:  70gr IMR 4350

.303 174gr lead:  32gr IMR 3031

450 Marlin 350gr lead:  53gr IMR 3031 /  400gr lead:  50gr IMR 3031

Whenever we get a new calibre we always try a few different combinations and then stick with what we know works.  If you come across an old Hornady book bound with plastic coils they have excellent trajectory tables in the back of the book. 

I will add a few as well. Most of these are on the high end so start low and work up...

The most accurate loads I could get out of the intended rifles.

Unfortunatly no. They are goin with me for spring bear though. I used the 115bergers last fall for whities and they were impressive. Bang flop. Excited to try the interbonds on a blackie!
