I no nothing about a "tip" but I do know about bullets.
The 8x57MM JS Mauser bullet is very accurate at long range. While the 150 grain flat base does well it will have a very steep trajectory due to the drag the flat base or cupped base bullet causes. This bullet slowing down so much faster is also very wind sensitive.
The 198 Spitzer boat-tail ( stolen design from the French) is VERY accurate at long range. It bucks the wind very well and hits very hard due to the higher velocity it maintains due to the less drag.
A rifle with a very good or better bore ( better gas sealing) the standard Mauser rifle,pick one, will shoot at 800 yards about 3 MOA.
If you are lucky enough to own a "Persian Mauser" you can get 1 MOA with good ammunition or hand loads.
The 8mm bullet,spitzer or low drag Match type has one of the best BC's out there from the turn of the last century.
As a young man I was so impressed with the German surplus 198 grain rifle loads I ran a program in the then new and state of the art UNIVAC-7 computer that filled a room. The data spit out on paper tape did in fact conclude the shape,weight,diameter,speed,rifling twist was darn near perfect for a military cartridge. The Germans don't make crap when it comes to weapons and their ammo.
The data I cobbled together stayed with me all of my life until I decided to build a true "Mile Rifle" in 8mm Remington Magnum. This beast of a cartridge with today powders will push a 200 grain Spitzer Boat tailed bullet out of my 29" barrel at 3,300 fps with sub-moa accuracy. The slightly larger bullet and shape really made a difference at long range. The Germans had really done their math right.
Several of my club's members shoot 8x57 Mauser with the 198 grain surplus ammo at out 800 yard man silhouette target with most of them getting 80% plus hits with their old Mauser rifle and carbines. Recovered missed bullets that hit the dirt berm are almost always badly mangled. These bullets hit hard and true at 800 yards.

Here is a short Vid of Pat shooting his 8MM Siamese Mauser, a much less powerful cartridge at 800 yards. The camera is zoomed out to 1,000 m/m so you can see the target and the electronic flash I built to the left of the target 50 yards.https://www.youtube.com/watch?v=NBwwzBOb_Nk
I have vids of members shooting 8x57 Mausers as well but have not gotten permission to post them shooting.
