#### on close vs open

On the subject of the Boer War

This is one of two memorable paintings for me:

Dawn of Majuba

2nd (Special Service) Battalion, Royal Canadian Regiment of Infantry, Paardeberg Drift, 27 February 1900. At Paardeberg on 27 February 1900, the 2nd (Special Service) Battalion, Royal Canadian Regiment of Infantry helped win the first significant British victory of the 2nd South African War (1899-1902). Although the Canadian success owed as much to good luck and stubbornness as training or skill, the victory provided a boost to the morale and confidence of the troops. This painting, 'Dawn of Majuba', by famous British military painter R. Caton Woodville, portrays the moment when news of the enemy surrender reaches the Canadians. The Boer defeat took place on the 19th anniversary of a British disaster at Majuba Hill during the 1st South African War (1880-1881)

I grew up with this painting as a backdrop.

This is the other

The Hitler Line

Ist Cdn Div in Italy - the Thompson smg is noteworthy. My father landed at Pachino with the RCR as a Pl Comdr armed with a Thompson - he said they were expensive if you lost one! An odd recollection reinforced by the fact that the Canadian Army was notoriously cheap! He also served through the Hitler Line, Gothic Line, Holland, Germany etc etc.

BUT Paardeberg has been an important part of the RCR tradition.

AP * that was an interesting video in the comparison of a M93 to a M98. In a later post a comparison is made of a rotating bolt head vs a non rotating bolt head in reference COC to COO. Now my question is this, does a M93 have a rotating bolt head? If it does how do the two rifles compare in action cycling

All Mausers from 1889 on do not have a separate bolt head. The bolt face rotates with the rest of the body.

If your gun is taking any effort to open you may want to have your chamber looked at. Even hot loads in my tikka I can open with my baby finger.

Only thing I can say is C.O.C is not the greatest for me for sitting at a bench shooting. The ammount of effort needed to push the bolt forward and pull the fp back really shifts things around on the bags and rest.

Bolt lift may not seem like a big deal in a sporting rifle shot off the bench under ideal conditions, but adverse conditions are where this would be a concern. Dirt, bad ammunition produced under the pressure of wartime, and/or elevated temperature could all be contributing factors to hard extraction.

Anyway, I think I've figured it out. #### on closing rifles, such as a Lee Enfield or pre-98 Mausers, typically have lighter firing pin springs and longer firing pin travel than later designs that #### on opening. This makes for a fairly long lock time. A heavier spring and shorter firing pin travel decreases lock time, but would require an inordinate amount of effort to close the action if it were #### on closing.

Thanks for all the information. It was very informative. Best as I can tell COC seems to be superior for rapid shooting. I'm still not clear however as to why there is no modern COC rifles outside of the AIA

#### on open makes it mechanically simpler to prevent firing out of battery, i.e. striker slipping from sear, doesn't it?

I have gone to the trouble to make a small ring mauser #### on open, turned out to be a waste of effort, no benefit.

Main benefit will be lock time. As prev stated coc have lighter springs and a noticeably longer locktime. I also converted a lot of Mex. mausers to #### on open and think it improved accuracy. Even the '98 benefited from a heavier spring.

The only way you can carry a round in the chamber in a COC action is with the rifle fully cocked, and hopefully on safe. I can't see how that would be safer than on half-#### myself, for reasons stated above.

How did you come to that conclusion? The record for the mad minute with an Enfield is supposedly 38 shots in 60 seconds.

This guys does 17 shots in 25 seconds with a COO rifle:

That is equivalent to 40.8 shots in 60 seconds and he only has 5 round mags, whereas the Enfield has 10 round mags. This isn't even their record for the even... I think its 18 rounds in 25 seconds which is equivalent to 43.2 rounds in in 60 seconds. With 10 rounds mags they would be even faster.
