welsh warrior Posted July 28, 2010 Report Share Posted July 28, 2010 at 100 yds what ftlb would these rounds still have?does barrel lenth and quality of rifle make a difference or would a 50 quid rifle still (hit as hard) as a 600 quid rifle?

welsh warrior Posted July 29, 2010 Author Report Share Posted July 29, 2010 kinda got it i thought it was one of thoes ones where you have to type in the info yourself ..very intresting to see that at 350 yds the 17hmr still has 35 ftlb of energy !!! still plenty to kill your target i never would have thought at that range it would still have that much force for such a small and light round,but thing is the 22lr has got more ftlb than the 17 hmr eg.. .22lr at 350 yds still has 52 ftlb and thats at 350yds ! is this becuase the 22 is more heavy and does not lose its speed faster than the lighter 17 hmr?

Good luck hitting your target at 350 yards with the .17HMR, unless you're inside a sealed chamber. The slightest breeze will blow it miles off course. Edited July 29, 2010 by Billy.

welsh warrior Posted July 29, 2010 Author Report Share Posted July 29, 2010 dont get what your laughing at ..i didnt say i was shooting at 350 i said that the power it still has at that range for such a small bullet is very impresive.

Paddy Galore! Posted July 29, 2010 Report Share Posted July 29, 2010 .22lr at 350 yds still has 52 ftlb and thats at 350yds ! is this becuase the 22 is more heavy and does not lose its speed faster than the lighter 17 hmr? Which round is this? not an HP sub that's for sure. Quote Link to comment Share on other sites More sharing options...

Dekers Posted July 29, 2010 Report Share Posted July 29, 2010 the round was the... copper plated hp .22 lr I'm not sure of the ammo you are talking about or how the program you are using works but I'm struggling with any .22lr holding 52ft lb at 350 yards, a sub has absolutely no chance, this would leave the barrel at around 100ft lb. Can you check the program and/or the ammo, heavy ammo tends to hold its energy better than light, but the likes of the hard hitting and heavy CCI Velocitor leaves the barrel at 183ft lb and is down to 104ft lb at 100yards, I struggle to believe it still carries 52ft lb at 350 yards! :unsure: Cheers Quote Link to comment Share on other sites More sharing options...
welsh warrior Posted July 29, 2010 Author Report Share Posted July 29, 2010 dont blame me lol ...it has all the info already on there so it must be right Quote Link to comment Share on other sites More sharing options...
stevethevanman Posted July 29, 2010 Report Share Posted July 29, 2010 The price of a gun does nothing to alter its power :unsure: Also the .HMR does have more power than the .22 at 100yds, the barrel length does make a differance but for a .22 LR, that is any length below 13" so im told as the bullet is at full speed by 13". For the HMR its generaly considered as any length below 16" of barrel that reduces performance Hope this helps. Steve Quote Link to comment Share on other sites More sharing options...
welsh warrior Posted July 29, 2010 Author Report Share Posted July 29, 2010 well if that thing is wrong then what will a 22lr be doing at 100yds and same for 17 hmr im totaly confused here haha Quote Link to comment Share on other sites More sharing options...
Paul223 Posted July 29, 2010 Report Share Posted July 29, 2010 at 100 yards ..... approx cos manufacturers vary .17hmr energy 136 ft/lbs speed 1902fps .22lr energy 79 ft/lbs speed 941 fps Quote Link to comment Share on other sites More sharing options...
welsh warrior Posted July 29, 2010 Author Report Share Posted July 29, 2010 wow i mean thats still a hell of a lot of energy Quote Link to comment Share on other sites More sharing options...
Colster Posted July 30, 2010 Report Share Posted July 30, 2010 (edited) According to the oracle that is Chairgun, a 17gr V-Max will still have around 147 ft/lbs (starting with 265ft/lbs (based on MV of 2650fps and a BC of 0.127)) at 300yards and an Winnie Sub from an LR would be 59ft/lbs (starting at 101.5ft/lbs and based on a 40.3gr bullet with an MV of 1065 and BC of 0.138) Perhaps more telling though is at 300 yards from a 130yard zero, the HMR has dropped about 14", the LR zeroed at 55yards is a little over 11ft lower!

welsh warrior Posted July 30, 2010 Author Report Share Posted July 30, 2010 so i was right lol .. ish ... but i am impressed by the power these 2 little rounds have at that range i mean you could take a fox wit that power ...not saying i would guys but you know what i mean Quote Link to comment Share on other sites More sharing options...

The Oracle that is Chairgun has something wrong..... CCI figures..... CCI 17HMR 17g V Max ... Energy, Muzzle, 245ft lb, 50 yards 186ft lb, 75 yards 161 ft lb, 100 yards 138ft lb. There is no way this carries 147ft lb at 300 yards even if you somehow manage to get it up to 2650ft sec at the muzzle! CCI 40g HP Subs Muzzle 97ft lb, 50 yards 82 ft lb, 75 yards 77ft lb, 100 yards 72ft lb....again there is something very wrong with Chairgun if it suggests this only drops 13ft lb of energy over the next 200 yards!!

Mr_Logic Posted July 31, 2010 Report Share Posted July 31, 2010 Agreed, those Chairgun figures are ridiculous. Do remember that these tools are low powered rabbit rifles at their heart. Just a pleasant warning given that I've seen comments about 'how much' power they have. It's all relative - 1000 ft lbs is easy for a CF to achieve at that range, and 308 has that kind of energy hundreds of yards away. A 308 has more power than those RF calibres at the muzzle, when it's at 1000 yards - something to bear in mind. Then of course, next to 50 BMG a 308 is equally piddly!

welsh warrior Posted July 31, 2010 Author Report Share Posted July 31, 2010 plan ... i have got a chrony so what if i was to put that at 100yds away and fire some rounds at it ? would this be valid data? Quote Link to comment Share on other sites More sharing options...
Dekers Posted August 1, 2010 Report Share Posted August 1, 2010 plan ... i have got a chrony so what if i was to put that at 100yds away and fire some rounds at it ? would this be valid data? They would be valid for your tape measure/gun/ammo/chrono! I've done this defore and found results to be generally slightly worse than the ammo manufacturers say (as you would expect), which makes the Chairgun figures even more daft! Worth starting by getting some muzzle data then moving the chrono to 50-100 yards or whatever! Quote Link to comment Share on other sites More sharing options...
