The Finns were eventually worn down simply because they were exhausted and could not match the sheer size of an increasingly efficient Soviet army.
The M28/30 was the rifle carried by a Finnish Civil Guard by the name of Simo Hayha. He was without doubt one of the deadliest sharpshooter/snipers of all time with in excess of 500 'victories' to his name. This does not include the scores that he took out using his sub machine gun. He managed all of this in 98 days. The Soviets eventually managed to stop him by shooting him in the face. Something as trivial as this wasn't enough to finish him off and he died in his sleep a very old man.
All 28/30s have recycled M91 receivers and woodwork (although some were put in newly made stocks when refurbished after the war). Barrels and sights are unique to this model there are a load of tweaks that the Finns included to enhance accuracy (pinched dimples in the magazine to eliminate jams, tuned triggers, shims between the stock and actions as well as an aluminium collar under the nose cap to help float the barrel. The barrels have slightly tighter bores than other Mosins.
