Mauser M03 - Accuracy with 243 Win and 270 Win

I've uploaded a new video, showing load development testing for my 243 Win barrel with a new bullet, being the Berger 95gn Match Grade Classic Hunting. This projectile is not too pointy and will feed well through the magazine. It should be ideal for all of the shooting I will do with my 243. After working up the loads with three shot groups I got to the top load of 43 grains of 2209, which looks to be the most accurate. I settled on a seating depth of 20 thousandths of an inch, which these Mauser M03 barrels all seem to like. I then fired a group with this new load at 300 metres.

At the end of the video I fire a quick test shot at 300 metres with my Mauser M03 with a 270 Win barrel installed, to simulate a first shot at a distant pig, deer or even a fox. It lands close to the group fired with the 243. :-)

What is not on the video is a similar single test shot fired with my Mauser M03 in 30-06, at 200 metres. I asked a guy who was finished for the day if I could shoot at one of his unused target circles, out at that range. The deeply seated clunky looking 180gn Core Lokt bullet from a Remington factory load landed right in the circle, first shot.

I'm happy to report that these rifles are working. :-)

I set the Zeiss scope's ASV+ ring to 300 and the shot was pretty well bang on at 300 metres.

I've added the picture below of the three shot group fired at 300 metres with my Mauser M03's 243 Winchester barrel, which measures 54mm across. The two loaded cartridges show a comparison of the two 6mm Berger 95gn bullets I've tried. Both are seated 20 thousandths from the lands. The longer bullet is the Match Grade VLD Hunting while the shorter one is the Match Grade Classic Hunting. As shown in the video embedded above, the bottom hole is from a quick test shot with my Mauser M03 in 270 Winchester.
