Re: Question about H1000 and 338 Lapua
Thought I would give an update on my Savage FCP 338. I ve got 60 rounds through it and the barrel appears to be broken in cleaning up quickly with minimum copper fouling. Even though I torqued the scope base screws to 30 inch pounds before scope mounting, they came loose. Cleaned the greasy holes and screws, and retorqued with Blue Locktight. I'll see how this holds up. Any advise would be welcome. Started with H1000, testing 89-91 Gr. with .5 increments. Seating depth .010-.040 out of the lands. All testing done at 100-200 yards. 89.5-90.5 grains produced the best accuracy, .030" off the lands at .5-.6 MOA average. 90.5 gr produced 2725 FPS. ES were excellent in with 5-10 FPS. I found a 20-25 FPS for each .5 gr increment. Started to see slight pressure signs at 91 gr/2750 FPS so I settled at 90.5 gr. Then tried 89 grains of Retumbo. I reluctantly cut into my much coveted lot that I use for my 6.5x284, but couldn't resist. Two 5 shot groups went into one hole each, perfectly round, at 200 yards. Both measured .25 MOA. I didn't bring my chronograph, but I expect the velocity to be in the 2700 FPS range based on my buddy's work with the same rifle. I'm going to pursue Retumbo and do chrono work and longer range testing based on these initial results and see how things go. Overall, I'm very impressed with
this rifle. Also like the NF G7 that I mounted on it. If I can get through my testing, I'm thinking of using it for big Alberta mule deer next month.
