I have a savage elite precision 338 lapua and just starting to reload my own ammo. I have Hornaday brass, vihtavuori 20n29 powder, Hornaday 285 gr. ELD-X and 300 gr sierra HPBT matchkings, and planning federal 215m primers when I'm able to find some. Any suggestions where I should start with powder? I was going to start at 90 gr. And go from there. Just looking for some good advise of where to start.

That is a really slow powder for .338LM I shoot 300 SMK and Bergers with Retumbo or N570 I just happen to have both. I have shot the 285"s in the past using H-1000.
With what you have I would use the 300SMK's. I would think 88 to 90 would be a go place to start.
If you can I would look at 29N41 it shows a load in the vihtavuori reload data. I didn't see anything for 20n29

Thanks for the advise! Ffl is hoping to get some retumbo for cheap in the near future, thats what I was planning on but got 20n29 first. Just didn't want to blow a barrel up, being my first reloading experience riflewise.
If you can't get retumbo then n570 or rl33 are a great .338lm powders. I don't think you will have any good results with 20n29 it really a 460

Ramshot LRT is easy to get, is a bit on the slow side, but not too slow. If you’re newish to reloading it might be an easier powder to work with.
General rules about powder burn rates: you need slower powders for bigger cartridges and heavier bullets.

I made a very accurate load with 285 elds and 24n41. I use 94.6 grains.
My best load at a mile uses 100 grains of LRT. My buddy’s rifle likes Retumbo. We also tried H1000, Re25, and Re33.

I run a AI AXMC 29in 1.9.3 barrel and I use 3 different powders
For 250's and 285's I use H1000.
For 300gr bullets I use Retumbo or N570
300gr 90.5 Retumbo AVG FPS 2786, SD 6.4
300gr 89.5 N570 AVG 2777 , SD 7.1

Would anyone happen to have any reloading data using N565 with 300gr A-Tips? Looking for a safe starting load and what to look for in velocity?
Thanks in advance for any information!

I’m out of town, so can’t check my log book, but VV load data isn’t a bad start. Have a look at N565 with the other 300 gr bullets to get a ballpark charge range and velocity.
