mod 55s is in .177 calibre and mod 60s is in .22 calibre apart from this they are the same rifle, it is also available in .25 calibre but not sure of the model number.
DO NOT DO THIS!!!!!!!!!!!! DANGER, DANGER, DANGER!!!!!!!!!!!!!!!! You are asking for trouble.
It all depends on the particular model. There are over 100 different models that shoot .177 cal BBs'
I'm a little perplexed, what is the caliber 4.57.177 are you trying to say 4.5 and .177. The Diana model 35 came in both .177 and .22 cal. It was made between 1965 and 1987
Oh, dude, it's like asking if pineapple belongs on pizza - it's all subjective! A .177 caliber pellet gun is great for accuracy and speed, while a .22 caliber has more stopping power. So, it just depends on what you're shooting at - cans or grizzly bears.
An air rifle could be made in that calibre. Benjamin made a model 242 and 247 in .177 and .22 calber from 1968-92 but not a model 243.
About two and a half hours. Take 177 and divide it by 70.
Walther gets my vote. --------------------- New Answer--------------------------------------------------------- The finest .177 calibre air rifles are Olympic Competition .177 air rifles. These will fall to the Feinwerkbau line of Olympic rifles. However these are not cheap. The average cost is around $2500. Next in line are rifles made by AirForce airguns. Benjamin PCP airguns, Webley & Scott PCP air guns, Daystate LTD airguns and a few other PCP (PreCharged Pneumatin) air gun companies. Crosman, Gamo and Avante make fine air guns and rifles but are not as accurate as the ones previously mentioned.
Take away 100 and add one...
177 x 177 = 1772 = 31,329
The Dianawerk / RWS target model 100 .177 cal was made between 1989-98. Its a very expensive rifle.
It does not.
