For those of us that have tried please help me with this question.
In a PCP with a 8.44 grain 10.5 FP was developed. What would hapen if a 10.5 grain pellet was used ? &|
Difficult question to answer definitively. The common theory states that a heavier pellet in a pcp rifle will be more efficient and develop a higher energy even though velocity is slightly lower.
That is the theory, but is does not always hold true.
For instance when I had my Pro-Target I set it up to produce around 780fps with AA Fields for about 11.4 ft.lbs, now out of curiosity I tried using Bisley Magnums to see what would happen - result velocity dropped to 680fps for an energy of 10.78 ft.lbs - so much for the theory in relation to that particular rifle.
Subsequent testing on my 400 series rifles has produced similar results.
