First thought that comes to mind: was the wind blowing?

That doesn't exactly sound like wind. Can you post pictures of the targets?

Re: New to reloading. Need help asap.

The thing that's bugging me about the situation is going from hole in a hole at 100 yards to all over the place at 200 and beyond. I've seen my loads get worse at longer range but not that much worse. The reality is that once you get to 300 yards the number of variables that affect the group goes up exponentially. INCLUDING the shooter. I'm not saying that is the root problem but it could be "part" of the problem. For me personally, it's always a part of the problem that cannot be discounted. That said, I think that it's something else... continuing on along that train of thought...

Are you absolutely positive that your charge weights are the same? How do you determine charge weight? When I plug your numbers into the G7 program the only drop it likes at 300 yards is your initial value of 1.5. The program back calculates velocity at around 2633fps. The minimum velocity listed in the Sierra Loading Manual, for a .300 RUM and a 200gr. SMK is 2700 fps and the "green" load (accuracy and hunting) is, for most powders, 3000 fps. They list 92.0 grains of Retumbo as their 3,000 fps load.

I think your charges are lighter than what you think they are and the bullet is not stable... In fact I think you may be dangerously underloaded but I'm just one of many internet voices so take that with a grain of salt.

Re: New to reloading. Need help asap.

Neck vs. Full Length resizing...for me, I generally try to neck size only as I feel having a cartridge that is fireformed to perfectly match your rifle's chamber is best. For those that say you need to full length resize for a hunting rifle to ensure smooth loading is an issue that I have never run into.

There is one exception to this rule for me. That is on my 300RUM. When loading neck sized brass for this rifle, the bolt will not always close. As a result, I full length resize this brass and 'bump' the shoulder back .001 or .002

Here's a great post about full length sizing and bumping the shoulder...

Re: New to reloading. Need help asap.

As far as charge weights, I loaded exactly to the Nosler book. I have another thread (sorry for mulitple threads) in the Long Range Hunting and Shooting section. I reloaded from 91 gr up to max of 95. I use two scales, both digital whenn weighing EVERY charge. The Hornady scale and, I can't rembmer off the top of my head, but something like TMG or TMN scale. Its a little red digital scale. I make sure the read ecxact. Still working on this issue. Loading up tonight to shoot tomorrow. Again, another thread in a different section that there has been discussion on if you would like to see what else has been mentioned. Thanks a ton for all the help guys.

I would encourage you to verify your charge weights with a balance beam scale. I have a RCBS Chargemaster and I have seen variances of .2 grains when verifying on my balance beam scale. A buddy of mine had the Hornady equivalent and experienced the same.

I for sure will invest in a scale as well. Forgive the ignorance here, just going off what I've heard or been told, but a local guy here in town said these large magnums could care less about a half grain difference. That seems like a lot to me. I weigh them out to be exact every time. I mentioned to him that I considered working in .5 grain loads and he said to not even bother. Either 1.0 up or down, but don't worry about the half grain loads, there pointless in a large mag. Not sure if there is any truth to that or not. Thanks again.
