Somchem for 270 Win.

Use the S365 start powder data for the 150 grainers, and work up from there.

The start load you have from Gordon's is already past the max load for 130 grainers, so rather back off to the start load for 150 grainers from the Somchem data, and work up to what is pressure safe in your rifle.

If 54 grains is the max for 130 grainers, it's going to be beyond the max for a heavier bullet.

I have just purchased a 270 win, busy researching some reloading data.

I am using S365 powder with Hornady 140 gr Interlock BTSP tips.

Anybody that can point me in the right direction.

I am looking at a start load of 54.6 gr that should give +-2800ft/s (according to Gordons reloading tool.

Just want to ensure that I am safe.

Struggling to get an idea online, very few load data for S365 with 140 gr tips.

Happy reloading!!]]> Reloading Methodology Joker270Win https://systemz.online/reloading-methodology/270-win-s365-finished#post-4022 https://systemz.online/reloading-methodology/270-win-s365-finished#post-1396 Mon, 11 Jul 2022 02:38:12 +0000
QL calculates about 55K psi. A safe load that ensures good burning characteristics and most probably a smallish extreme spread.


QL knows of what it speaks  ;)

It gave 34fps ES over 25 shots which were split between two different days, one cool and one hot.]]> Reloading Methodology oafpatroll https://systemz.online/reloading-methodology/270-win-s365-finished#post-1396 https://systemz.online/reloading-methodology/270-win-s365-finished#post-1395 Sun, 10 Jul 2022 11:13:28 +0000 Reloading Methodology Tripodmvr https://systemz.online/reloading-methodology/270-win-s365-finished#post-1395 https://systemz.online/reloading-methodology/270-win-s365-finished#post-1393 Sun, 10 Jul 2022 09:15:52 +0000
This was inside of the load parameters from 3 current sources but treat with caution yada yada yada.]]> Reloading Methodology oafpatroll https://systemz.online/reloading-methodology/270-win-s365-finished#post-1393 https://systemz.online/reloading-methodology/270-win-s365-finished#post-1392 Sun, 10 Jul 2022 06:10:54 +0000 Reloading Methodology Tripodmvr https://systemz.online/reloading-methodology/270-win-s365-finished#post-1392 https://systemz.online/reloading-methodology/270-win-s365-finished#post-1391 Sat, 09 Jul 2022 12:58:50 +0000
What are your rifles dimensions and parameters you are going to use? Quick Load can give an idea of where to start with the IMR4350.

************************
The powder I have is H4350. I have access to quick load, not mine, but I may use it. I found that the loads suggested and max vary hugely, even on sites like Hodgdon, Hornady and so forth.]]> Reloading Methodology Treeman https://systemz.online/reloading-methodology/270-win-s365-finished#post-1391
