6,5x55mm kulkų analizė po šūvio (anglų k.)

Turininga ir vaizdinga 6,5x55mm kulkų analizė po šūvio. Kulka, masė, kulkos vaizdas po ekspansijos.





• The impact velocity was made to duplicate modern 6.5X55 loads at 100 yds.
• Expansion was measured at the widest part of the bullet. Take a look at the pictures when comparing the expansion of different bullets, sometime a sliver of lead or copper at an odd angle can give deceptive results.
• Test rifle: Winchester Model 70 Featherweight 6.5X55 Swed
• Test media: Wet newspaper....lots of wet newspaper!!
• Disclaimer: I know wet newspaper does not give identical result to flesh and bones, blah, blah, blah....

156-160gr............2400-2500fps
168gr..................2300-2400fps





The test was perform exactly like the first one to make the results as comparable as possible. The only difference is I don't have my Winchester anymore so I used my Mauser M38.

I'll keep the latest results seperated for now so it's easier to see. After a couple weeks I'll insert the results in the older test so they are all in weight order. Enjoy!
