third powder for .243

The 105 should go well with n165.

I've used H4350, H380, H414 and IMR4064 with 85-95 gr bullets in my Savage 110 243. I have had good groups with all of them but have been using IMR4064 the most as I have a bunch of it. All loads were developed using Rem 9-1/2M magnum primers, with no issues.

I use h414 for 100gr projectiles. H4350 should work as well.

I’ve had good results with H4895 for 85g Sierra bullets, and with IMR 4831 for 95 - 100g (Nosler and Hornady).

I've used several powders in 243 including ramshot hunter. Hunter is a lot more temp sensitive than most hodgen or imr powders. There is data on hodgen website for hunter.

Others I've used are h4895, imr4895. Imr 4350, h 4350, and win 760. There is also data available fir h1000, imr and h 4831.

With 243 you definitely have a lot of choices for powders.

as title says, thinking about a third powder for my .243 loading. currently using IMR4895 for weights 80gr and lower and IMR4350 for 87gr and above. I don't hunt or compete but I do love hunting for that 100 yard clover leaf. So I'm looking for a consensus on a third powder to try for weights 75-105gr. Read somewhere Ramshot hunter might be a good choice though their load data can be difficult to find. suggestions please.

I settled on 4831SC for the larger bullets in .243.
These guys tested a few powders - might take a read here:

My favorite powder for the 243 is IMR4064. I use it with Speer 85 gr BT and CCI 200 primers. It is the most accurate load in my Sako.

H414/W760.

My Marlin X7S .243 shoots really good with MagPro. It gets an honest 3,100fps with a 100gr bullet from a 22” bbl. Accuracy is within normal range for the rifle.
I do use a magnum primer with it. Being a spherical powder, it does meter well, but I weigh individual powder charges...
IMR4831 is synonymous with the .243.... My older brother used it in his .243 that my nephew hunted with.. They took a LOT of meat does with it throughout the west while my brother was in the air force.

IMR 4831 with Berger 90 gr hpbt works well. With IMR 4350, Sierra #1530, 85 gr hpbt is a basic load. Both BR2 primers.

Ramshot Magnum ... Been available a bunch lately ....

Works really well with 90 and up bullets

H4350 is my go to in most of my rifles.

Varget has been my light bullet go-to powder for 243win, with H4350 my heavy bullet favorite. H1000 doesn’t make me sad in heavies, H4831 and 4895 for the mid weights there.
