Sako 75 300 WSM problems. Where do I start.

[MHO]

I am having problems with one of my rifles. Sako 75 Stainless Hunter 300 WSM. VERY FRUSTRATED. I am getting flyers. Not talking just a little. You get past 200 yards and one will be two to five inches off. One out of the three are flying. It doesn't seem to matter if the barrel is hot or cold. Everything we shoot is hand loads. We have tried every recipe. Conditions does not seem to matter. Ive even had a good friend who is a great long distance shooter check it and it does the same. I had the scope sent to leupold and had the BDC recticle put in. I thought it might be that. I had that checked and its not. WHERE DO I START?

A loose scope mount?
A loose scope base? (I had a screw bottom out once that made me think the base was tight, when in fact it was just loose enough to cause problems.
How many firings on your brass? Have you annealed? Neck Tension on brass can cause that as well.
Have you checked your action screws lately?

These would be the things I would check first.

Have a look at the following thread...

You may not have the same exact problem. But, the troubleshooting priciples seem applicable.

Gary and Rscott, thank you for your input.

Bedding. As it heats up it is touching somewhere maybe.

Action screws loose?

Mounts/rings as mentioned?

I had a 300 WSM. If you are using Winchester brass, chuck it and buy some Norma or R-P. You should see a better result. Try switching primers if you haven't tried that yet.

No problem. I could only get 3 useful loads from the Winchester and it would go bad whether I would anneal or not. First load would fire form, 2nd load group nicely and keep ES down, and 3rd load after sizing would be marginal. After that nothing good came of it.

MHO, you should make sure your barrel is tight. I have a 75 and I was having the same problem. I miss a huge 10 point !!! Just sayin!! I don't know what I am going to do. I call SAKO ( beretta) they said to send it in they will reseat the barrel. I am thinking about not sending it and getting new barrel for gun.

Does anyone have any suggestions?

Sako barrels are some of the best factory barrels you can buy. If they are willing to reseat it for free i would try that first before spending the money on a new barrel.

You are right about the Sako barrel, that is why I bought the gun. Everything about this gun is great. I am just not sure if I am going to feel right with it with this barrel, ie, threads may not be square (even). I am thinking about just going ahead and getting a custom barrel and a McMillan stock. I want to make sure that the bullet is gone where I want it. This barrel never really shot like I thought this gun should. I know that it may have been just the barrl lose, but if thats the case I have shot this gun with the barrl ose many times. I need to make sure that I did not mess the threads up.

If anyone has any suggestion please fell free to help me, whether it be opinion on keeping this barrel, or what to do to accurize the gun...

Thank you

I am having the same prob. I discovered that my barrel is lose. Check your barrel. I am thinking about going ahead and changing the barrel. I am doing some research, learned that the Sako barrel all be it a Great gun their barrel are to thin. It whips with the WSM rifles. Let me know if that is the case. Hope this helps.
