Re: Load Developement ???

I did have a couple groups that were awsome verticle spread (like less than .5 inch, but spread out horizontal almost 2 inches.

I probably just need to pick a better day with no or very little wind and really watch my form.

I was thinking that the Re-25 would be a good one because it book lists higher velocity, but I did notice that it sounds different. Its more like a pop than a bang and made me think something was wrong, but they all did that with the re-25.

Might have to try out Retumbo next. Ganna have to get me some more bergers I can tell you that already!

Don't switch!
Use one powder until you find it doesn't work. The gain in velocity of one powder or another is not worth the effort to change.
If you are getting very little vertical with that one load I would bet it has more to do with form than wind unless you have a lot of wind.
The problems than I have had with form were unbelievable. I found out after I fixed my form that the load I couldn't get to shoot before would do under 1/2" at 100 yards with one of the better groups at .381. Not bad for a sporter weight 300 win mag.
My biggest problem is being patient enough to do one thing at a time.

Why is it so important that you find the max pressure?

If your having trouble holding the rifle still I would invest in a leadsled, that way it takes all the human arror out of it. I use one on all loads I work up that way I know it wasn't me that made it go wrong.
I have found that the H 1000 works best in the two differant rifles that I load for. One is shooting a 160 Sierra BT and the other is shooting 160 gr. Nosler Accubond. So it all depends on the rifle as to what it likes the best.

Lead sleds can change POI. I've witnessed this myself. I think it's the harmonics. Otherwise I have no idea.

I have found if you don't get the eye inline with the scope it will change.
It is differant when you look through the scope while it is on the lead sled that is why you need to be careful when looking through the scope and make sure you are lined up.
Just like one note someone else said in this fourm it is just like when you are a passenger and looking at the speedometer and it looks like you are going a differant speed then you are.
