Looking for a Ross...which one to get?

[Gustro79]

Early Mk. IIIs HG and issue had the small aperture. These were discontinued, and the larger size was standardized; earlier issue rifles were altered. Not much chance of finding one.

Just got the 1905 Ross. It is also great. Excellent bore. There is a handguard crack but it is a very simple glue and clamp job. Appears to have seen little use based on the bolt. Has a few extra weird features that the 1910 doesn't have. I am suprised that the 1905 is shorter and much lighter than the monstrous 1910. Random thing... the 1910 is longer than my already long Swede M96 and the 1905 is shorter.(Pic)
As far as match shooting goes, the 1905 has a few apparent practical advantages. First, the aperture is smaller or appears so as it is barrel mounted. The 1910 bolt may force you to break position more during rapid fire as the bolt reaches farther back during extraction and may hit your face if you don't move. The 1905 bolt stops shorter.

I will do some bench and practical shooting from the positions. The first impression is that the 1905 may be a better high-power rifle and the 1910 would be a much better bench rifle IF the aperture were smaller.
