Default 240gr LSWC "Keith" and VV N340?

I have a S&W Classic 6,5" .44 Magnum and have purchased some VV340 powder and Magma Keith 240gr Lead SWC bullets and would like some data on reloading - Should I get a different Powder or has anybody tried this combination? Grateful for any info on this!

Found Data: 10,0gr gives 1023 f/s and max 11.ogr gives 1101 f/s
So I will therefore change to N105 or N110

N340 is a nice powder. I've used it for .45acp but abandoned it on account of price and availability. Vihtavuori does not publish data for your specific combo. For N340, only jacketed 240 and 250-grainers are listed. If you insist on using N340 for your bullet, I would try the START load and if all goes well, NOT EXCEED IT.
There are better-suited powders and oodles of data specific to the Keith 240 published.

You'll have better results with VVN-110 . Try 18.0 - 20.0 grains N-110 with that bullet . IMHO both N-340 & 105 are too fast for that case / bullet combination . Above load with CCI 350 LPM primers .

I use it in 44 mag and found it very clean but with a 240 gas check bullet. N340 to me is in the same class as Unique. I can't decide which is more accurate. Close to top mid range is where I use it for target shooting. I like 2400 more for top end loads. N340 is my favorite 9mm powder.
