Finally got around to verifying zeros for our upcoming hunts. We've done very little shooting this year, a bit of health issues for the first four months, and then playing catch-up on the "home place" since then.
Fired a few "fouling rounds" through each rifle.....as I just did our semi-annual bore cleaning!
After "fouling", did the usual 300 yard check. For a zero check, I usually only fire two rounds. These is not load development, merely a zero check. Both rifles required a little adjustment.....fire two rounds, adjust, fire two more.
The wife's rifle, a box-stock (still with factory bedding) Win., Model 70, .338 WM (Barnes 225TTSX's) produced an average of approximately 0.60 MOA for the four shots. This was with the two shot groups averaged together. Not to bad for a factory bedded "Mattel" stock.
My rifle, shooting the same format, produced two, two shot groups averaged together equaling approximately 0.45 MOA. This rifle is a semi-custom .375 AI, shooting Barnes 250 TTSX's.
While not bench rest quality shooting, these are both 9 pound (hers, a little less) hunting rifles. For those that argue, that "larger" bore, heavy recoil, fairly light weight rifles can't be shot accurately....I'm convinced they can! I think these can get the job done out to our "self-imposed" limits of 600 yards. Not true long range....but not a "chip-shot" either! memtb
