best viht powder for 243

[Tikkat1x]

Right chaps, i will shortly be reloading for the 243 when my variation comes through, so its homework time,
i can get hold of Viht powder fairly easy at the moment so i will want to use that,
i have 4kg of N555 that i had for my 6.5 creedmoor so it would be nice to use that, and i believe i can, i also have a fair bit of N140 that i use for my 223, but iv also read that N150 and N160 will work well to,
bullet weight yet to be decided so open to suggestions, favoured bullets are Hornady and sierra, will be used for roe deer only, and a bit of long ish range gong bashing, rifle will no doubt be a tikka t3x 1:8 twist 20" barrel,

thanks.

What bullet weight ?

 

[Tikkat1x]

As above mate, yet to be decided

May I suggest download the vhit vouri app it's free. With a 1:8 ratio even the heaviest bullet should stabilize and the VV app gives alternative powders with suggested min max loads for each manufacturers product

 

[Tikkat1x]

I have that mate. Just wanted real world suggestions

I've used N140 for many years. Speer 90 SP , lit up by CCI BR primer. In three separate rifles,Brno Ruger and now Remmy, no change on powder weight gave good results, just a tweak on COAL for each rifle.
Powder weight 39 grain.

viht N160 80gr Barnes
Personally i would pick my bullet then choose my powder.
Used N140 for 65vmax also

I used 100gn Sierra pro hunters and n160 when i had a 243. Used to clover leaf in my tikka

N160 and Sierra 85 grain gameking hit a sweet spot for me.

N160 was the ‘go to’ in my 243 when I had it, variety of different bullets from 80gn to 107gn (1:8 twist barrel).

N550 is my favourite using 58 vmax and 70 nosler bts. As said download the free info from Viht I’m sure you could use up the 555

 

[Brighty3006]

N160 for me. 100 grain prohunters

Vihtavuori .243 Load - N555 seems to work across most bullet weights, so if you have it, stick with it. You can try N140 as well if you have it. I would recommend having one powder that ticks multiple calibers if you can. Look out for bullets that you can source locally and are available in plenty when working out a load. What works for others may not work for you, so its an excercise worth undergoing to find that load that is consistent for your rifle and hits the sweet spot. As 10 people, you will probably get 10 different answers all of which works for them but may not work for you.

I use N140 across multiple calibers and it was based on availability. I worked out the bullet that works with the poweder as it was easier to order bullets online than get multiple tubs of powder. Just my view.

N140 for 75 and 87 Vmax. Very accurate.

Use it in both of my .243s

N160 with 90g sierra TGK's and 103g eld-x is what I'm currently using. Previously I've had really good success with 160 and 85g gamekings and 100g pro hunters

 

[Tikkat1x]

cheers chaps, im thinking i will try Hornady 87gr V-max first and use my N555,
many thanks.

I use N135 for 58 grs vmax for fox as sampo say it’s a bonus if you can run two different calibres from the same powder

 

[3.5mag]

N160 for me & 75gr Vmax.
Below max, 3160 FPS average & very accurate.

What’s your twist rate mate?

 

[hendrix's rifle]

What’s your twist rate mate?

1-8 for the hornady Eld-x and 90g TGK. The TGK won't stabilise in a 1-10 because they're just too long
The pro hunter and gameking however were 1-10
