I just put some thru my .338 win.mag on the weekend and wasn't all that inpressed.They where 180 gr.Nosler Accubonds with 73.0 grs. of IMR 4350 (grouped 3 shots in 1.75" to 2.25").They seemed to be all over the place and didn't group as well as the 200 gr.Hornady's (1.25" groups).I'am not sure but some other people have said the lighter grain leads don't seem to stabilize and i get the general feeling most people opt.for the 225 gr.bullets.
Thanks for your input DW.
How many rounds did you fire? How far away? Did you only fire three rounds all together?
I have a few more 210 ballistic tips, but after I finish them off I'll try the 225s. I wasn't all that impressed with them the last time, but that was then and I hope I have improved in my shooting sense then. I'm starting to believe my Ruger M77 just isn't able to perform at the level I want it to. What are you shooting for a 338? What are you able to get from it? I was hoping I could put three to five rounds into a two inch circle at one hundred yards, but I'm lucky to do that at sixty. This is off the bench mind you. I know that it can be an intimidating round, but I am sure my shots felt good and should make the mark. I only fire her three to five rounds at a times.[/b]
All together i fired 17 rounds of the 180 gr. Accubonds.I usually fire in groups of 3. My rifle is a Winchester Model 70 Classic Sporter with a 26" barrel and topped with a Leupold VX-II 3X9X40 mm and Leupold bases/rings so it's highly unlikly i have scope wandering. I always fire @ 100yds.(my own range since i live in the country). Like i said the 200 gr.hornadys with the same 73.0 gr.charge of IMR 4350 grouped o.k..My next bullet i'll try will be the 225 gr.Nosler Part. probably teamed up with reloader 19.
Thanks again DW.
I think I will be looking for another rifle for next year. I like the action on my Ruger, but I have lost confidence in it's accuracy. I'll see what happens when I try some different ammo. I also shoot a 26” barrel and I'm scoped with a Nikon pro-staff. It's not the best scope in the world, but I'm not ready to blame my bad shots on it ether. I am going to try Honadys next time around. We will see...
I realize this response is a little late but, I purchased a M77 in .338 WM and had exact same problem. My solution was floating the factory barrel with a 1/8 air gap then lapping it. Next I tried a variety of powder/bullet combos. Most were unacceptable but, the 225gr accubond or the 200gr ballistic silvertip both worked great pushed with 70.5 of IMR 4350/ BR-2 primer and win. brass. AOL was set to 3.415. 3 shot groups averaged .7 at 100yrds and 5.0 at 400yrds.
Hopefully someone with similar problem with M77 .338WM will benefit from this.
Thanks AMU Shooter,
Better late than never. It's strange how we can come across a question that has been around for such a long time and then just pick it right up and go on.
The good news is, my groups are back to where they belong now. I fixed my problem by selling my Ruger and buying a T3 Tikka. (Great price too) I know that was a short cut of sorts, but my Ruger was also a little heavy in the woods and that was part of my logic. My long time hunting buddy, who bought it, had used it to take a nice moose back in 1995, so he was not as fussy as I was with the 1" or so. I must tell you that I am very impressed with the bolt's action on my T3 (very smooth). And I love the down range accuracy I'm seeing. No bragging just happy with what I'm seeing. The trigger came factory adjusted at three pounds and I can adjust it myself to two pounds. I think my rifle is just under eight lbs. now and that's scope and all. The recoil feels about the same and it's nice to have something new in the gun cabinet. You know, I have spent about ten years telling people how much I liked that Ruger, it feels so strange to have a new rifle take it's place. In a way, she reminds me of my old dog that I had to put down. Got a new one of those too. Thanks again.
Accuracy. What an incredible way to give yourself a true advantage.
Go to your club and get a bunch of guys together - and put a target out there at 250 meters. Break out the deer rifles and see who can shoot a decent group, even off of the bench, at this distance. I think you will be shocked at how few can do it.
So - with that in mind, I recently set out to try to develop a semi-custom rifle that I could afford and that would shoot - repeatedly - at MOA.
I started with a platform that I love...
