Tac,
RL17, IMR 4895, H4895 and the elusive now Gucci priced Varget are but a few highly successful powders I've used in my K31 loads with absolute outstanding accuracy 100 to 1000 yds. Sadly I went from one powder to the next as supply / availability vanished and I was forced to buy another powder & re start the "load development " process. Varget dried up, re start with next powder I could find..that dries up, re start. By forces of market conditions, I ended up with loads for a lot of powders as I had no choice but buy and shoot what I could find. Hated that but reality forces adapting to real life.
The limitations and restrictions you suffer in obtaining any Vhit powder replicates exactly why in 2008, here in Virginia, I dismissed Vhit powders entirely. If I can't get them, why load develop anything with an odd pound found here or there ...and very improbable that was. I have no doubt ..zero doubt how great they are but higher cost, nil availability canceled them off the menu in 2008. Now if your shooting life is low low volume of use, then perhaps gaining a pound or two if you can find it might be fine. Such is the case with Leon who manages satisfaction with microscopic amounts of Vhit powders found and is all good with that , it pegs his Gourmet meter for Finn , Swiss or Swede "anything". He has some good loads and good results with Berger bullets, Vhit powders, Lapua bullets and all 3 of them are not easily found in good times over here !
I shoot what I can get and I'm not suffering by that approach. I am not suffering on performance nor accuracy and I am not bleeding from the high costs of VHit, Berger , Lapua products which I can't get anyhow ...worse now in Biden's America. Even worse ? ...yes, we can't find primers and often its a long trip of several hour away to pay over 125 for a brick of 1000 primers, only made worse by high cost of fuel to get there and back.
I fully understand and appreciate the aspect of shooting what you can find. Making that reality work is what is necessary. I shoot every weekend but the Berger & Lapua bullet reloaders ?.... I see them maybe every 6 weeks. VHit powder reloaders...they don't exist on 1000 yd line ...never and I mean never. My peasant fare of Nosler & Hornady bullets and American powders found, works just fine. Of course, in Leons outlook, I am a wretched peasant using the scraps found for my hand loads. I consume a lot of scraps thankyou very much !!!
Wait a minute...travel 3 hours one way for primers ? I must be in England ~~~~~~~~~~~~~~~~
