100g 243 n150 powder

This has been discussed recently on here. If you are using top 6mm bullet weights in .243 and are using a Viht powder, you should really be using N160. It is the perfect match.
Testing drops @ 200yds with 100g Pro Hunters below. Match the right powder to the right bullet and keep all your reloading processes consistent and the results will come.

What depth were they seated also what grain powder did u use thanksThis has been discussed recently on here. If you are using top 6mm bullet weights in .243 and are using a Viht powder, you should really be using N160. It is the perfect match.

That is not really relevant to your rifle. They are all different. What works in one rifle will not necessarily work in another and that is certainly the case in mine as it has a tight chamber and/or a tight bore. I see pressure signs very early in mine. If I tell you to use my load, you could well end up with sooty cases and an underpowdered round that is not legal for deer. You need to work out what is best for your combination of rifle and cartridge.
If you have access to a chrono, read up about Satterlee testing or OCW. That is the best way to identify accuracy nodes whilst using as few components as poss. Seating depth wise, use the COAL given by the bullet/powder maker.

If I haven’t got access to a chrono but want to set up a load for Sierra 100gn soft points for my 243 how would you find an accuracy node? I’ve set up an 85gn HPBT with a chrono that I’m happy with but not sure how to go about it without one.

I use N550 with 100GR pro hunters in my .243. Pretty happy with the results and accuracy so far.
Read this about how to use the OCW method. Chrono is always a good help but I have worked up a few different loads just using incremental charge weights and shooting them in a round robin exercise as described in the link below. It relies on you being a known good shooter and being able to produce consistent technique and shooting ability. If you are comfortable and confident with that, it will certainly produce the results you want.

Any thoughts on N150 with 70 grain ballistic tips?
I use 42.1 grains of N160 with 100gr gamekings seated 10thou off the lands in my .243 R8, less than 1/2" at 100 yards

Hi ! What speed did you get ? What is the length of the barrel ? I do (Blaser R8 - 580mm) 100 grain Sierra GK - VV160 - 40,0gr., V = 880m/s.
Agreed

Hi Tikka, The question worries me a bit.
I hope I am wrong, but because you've asked it, it gives the impression you don't understand the importance of head space, bullet jump, and the relationship between them and dangerously high pressure spikes.
As Cottis mentioned, the relationship is specific to a rifle. You can't just copy ANOs bullet seating depth.
On a positive note. Experimenting with your reloads to refine accuracy is very satisfying, once the physics are understood.
The Berger reloading manual has a good article. I leant a lot from it.
