Default Hodgdon Info.

I assumed (oops, I'm learning the hard way) that since Hodgdon had load data for the 17FB I would be good to go with the 20VT. Do you think the heavier 39/40's will help or hurt? Thanks, Les

My limited experience with it is in my 223, and 204r...so far. In the 223, it was very accurate, with no signs of pressure up to the top. results are good enough all the way through that I backed off .8 gr, and load there, the rest of my brass for it...good groups, no pressure, easy to meter...what more can a guy ask for? I will try to duplicate it, of course, again, then on to loading. It performed about the same in the 204, groups small enough all the way through, I will pick where I think the loads start to get real tight, and duplicate, test again, and load from there.

I know the 8208 is too slow for my 221 Fireball. The 20 Vartarg is between the 22 and 17 Fireball in terms of bullet to case capacity. It might work. If you have H335 loads for the 20 VT you could start a grain lower than min for H335 and work up using the heaviset bullets. Like Oleman said however, I think you may find the 8208 too slow a burn rate to work real well in the VT in terms of getting top velocity figures. In the 17 FB and the 223 however, it works great. Best of luck and let us know what you find.

Default slow 8208

Dean, you were dead on when you said the 8208 would be to slow. My 20VT with 22" barrel and 19.4 gn 8208 and 32 Vmax only made 3105 FPS. My loads of 18.6 H4198 and 35 Bergers were 3475 FPS.

32 Hornady V-Max IMR 8208 19.4 CCI BR4 Rem case 3760 fps Wilson 1:12 D. Moore, .3 groups

This load is posted on the 6mmBR website on the 20s page, for the Vartarg, so this D. Moore fellow is obviously getting some good speed out of it with 19.4 grains. How many grains were you using and were you showing any pressure signs.

Despite thie info from 6BR, I would think there are better powders for the VT.

Default NO pressure

I think he would have to jump a whole grain to 20.4 to get those kinda speeds. It would be a compressed charge. The speed was so low I didn't wast alot of time with it. I will work up to that if I can and let you know how it does.
