Took my 10 year old’s ‘98 Mauser 7x57 to the range today, with some reduced loads I cooked up for him. The first load was 22.5gr of IMR4227, 140gr Nosler partition 3.065”. The second load was 29.0gr IMR4198, 140gr Nosler partition 3.065”. The 4227 was very mild and is supposed to be 2000fps. The 4198 load was a little stouter and is supposed to be 2300fps. It is all sighted in and ready for him to give it a go.





This was at 50yds. The smaller of the two groups is 4227, the bigger is 4198.
