I just reasently bought me some 250 grs Barnes X bullets witch I'm planning to use for moose and seal but I don't know what kind of load I should use. I have plenty of Vihtavuori powders to work with

I have always had great luck with the 250gr x backed by RL19 or IMR 4831 ,it usually runs around 2700-2750fps

How much powder did you use?

For the 250gr "X" bullet Barnes manual shows:
* VIT N160 sarting at 63.5grs/ max of 68.5grs.
* Re 19 min 66grs/Max 71grs.
* IMR 4831 min 63grs/max 68grs.
Work up carefully. They also recommend that the bullet be seated 50 thousands off the lands to start.

Iam using 70 gr Reloder 19
Win brass
cci 250 primer

I get 2645 fps in my win mod 70 classic with a 26 inch barrel. Accuracy is around 1.5 to 2 inches at 100 yd.I have now changed to the 225 gr tsx.

I made few rounds with 74,2gr of Vihtavuori N560 and I got velocities from 2670 to 2756fps and accuracy was about 2 inches from 100 meters. Velocities seems to be altering a lot with N550 and N560 powders. I think that I will try N160 tomorrow and hopefully get some better results.

I can't say if it will make any difference in your rifle but you may get better accuracy with standard primers rather than magnum primers.

I've used this load for my Win Model 70 since 1970:

74.0 gr. H4831, 9 1/2M primers, Sierra 250 BT -> 2749 fps

The powder was around a dollar a pound then.

I finally magnaported the barrel, and it is a kinder, gentler freight train now.

It has always shot 3/4 groups at 100 yds, some of which I am sure is me.

Some years back, I stuck a Fajan laminated stock on it. The original had a knot in it that warped it against the barrel in humid conditions. I was always amused by the carelessness of the wood and the amazing accuracy from this unremarkable gun. In 1970, it was the only stock gun you could get a 338 in.
