308Nut Report post Posted July 29, 2009 I am trying to find a new load for my 300 um, and was wondering if anybody here has used vihtavuori powder and if so what they thought about it. Thanks for any of your help. I have used the 300 RUM extensively and VV powder extensively. Just not together. My experience with the VV powders is very positive. The Finn's make reloading products with EXTREME precision and consistency. My best loads in a 2 different 300's was RL-25 and the 180 ACCUBONDS. Share this post Link to post Share on other sites

loco4coues Report post Posted August 1, 2009 sorry I don't have any experience with that powder. I do shoot a 300 UM, and I do reload my own rounds. I shoot a 165 gr swift scirocco with 98.2 gr. of reloader 22. It is an awesome set up for my gun and for my needs. Share this post Link to post Share on other sites
ajohunter Report post Posted August 1, 2009 I have a load for my Ultra mag using VV powder...... 125gr Sierras with 96.5 gr of N165 powder. The rounds are flat shooting but screaming out of the barrel so I dont shoot this load often But the groups are half inch at 100yds. Share this post Link to post Share on other sites

Very very accurate in our three rifles!!! I tried the scirocco and had no luck, but will try that RL22, thanks for the info!!! Same deal for me and another buddy of mine. I would guess that this is one of the most popular loads for 300 RUM shooters. For those of you shooting the 210 Bergers you should give the 210 JLK Long Tails a try. Very accurate with a higher BC. Good luck! Share this post Link to post Share on other sites
308Nut Report post Posted August 1, 2009 Dont over look the 208 AMAX. IMHO it is a better deer bullet and has a higher BC than the 210 Berger. It is publilshed at .649. I have tested it out of my 300 RUM at .671 which is even better. Share this post Link to post Share on other sites
308Nut Report post Posted August 3, 2009 308nut. what are your specs for your RL-25 and 180 accubonds (OAL, Velocity, Grains, Primer)? will others share what their specs are for the 210 VLD and Retumbo? thanks. I have been getting my best groups with: 97.5 grs. Retumbo 180 gr. Nosler Ballistic Tip 3.650" OAL 3240 fps. .40" 3 shot groups. extreme spread for a three shot group is usually 8-11 fps. BTW i have a sendero 2. what are all your specs? My specs were: 90.0 RL-25 under the 180 AB. Velocity was 3300 FPS. COAL was 3.700" Federal 215 match primers. Remington cases. These specs will yield quite a bit less velocity in your factory rifle. You will need more powder. My barrel was a custom "tight neck" and benchrest chamber which yeild MUCH higher pressures than a factory barrel. This is why I was getting so high a velocity with so little powder. Max book charges would blow my barrel in half. I was also using 93.0 H50BMG under the 208 AMAX at 3.700, getting 2975 FPS and consistent .25 MOA accuracy. H50 may be a bit slow for a factory rifle.

308Nut Report post Posted August 3, 2009 are you going sheep hunting this week? Yes. I leave Friday after work. Season opens on the 10th. I flew the area yesterday and saw a good bunch of rams. I dont know if I will get one this trip or even this year. I promised a friend who has never harvested one he could have first crack. I think the one we are after is legal. We need to scrutinize him more closely though. Share this post Link to post Share on other sites
