What yardage do you zero your PCP at?
« on: May 06, 2010, 04:40:50 PM »
I'm tweaking my 850's regulator to get a little more velocity and then I'll test 14 types of pellets this weekend.  I'll do a 5-shot group of each type, take a break and then test them all again with another 5-shot group.  Most of the shooting I do is 20-60 yards at starlings, pigeons and ground squirrels.  I'll occasionally take shots at further distances.  I'm torn between testing all the pellets at 30 or 50 yards.  I understand that a pellet that groups well at 30 yards doesn't necessarily group well at 50 yards but not the opposite.

What do you guys test your pellets at?

Generally a new pcp, I will start off with a new scope and mounts and set the target at 30 yards. If for some reason I cannot hit the target paper then I will move the target into 15 to 20 yards. I have found that some springers need the shorter yardage for setting up the scope but all my pcp's have been spot on at 30 yards..

All three of my PCPs are zero-ed for 50 yards....I only adjust the elevation turret if I shoot closer (GTA 30 yard shooting matches).  I`ve used all three to shoot out to 70 yards last winter....consistantly hit a paper coffee cup filled with snow when there`s no wind.

Doug, I recommend using Chairgun software . If you input pellet speed and some other variables it can optimize zero distance for your rifle and pellet.

I guess I should clarrify.  

What distance should I be testing pellets for accuracy at?  Not necessarily zero.

50+ yards,
« Reply #5 on: May 07, 2010, 12:38:52 PM »
not for "zero" (I use 25 for that myself) but to check the pellets themselves 50 + yards.
 Iuse JSB Express 7.9g just under 1000fps for Squirrels out to 70 yards, 80 yards on Starlings, "if" the 8.4 had groups as well at range (50 yards) I would be using those. Both pellets grouped very well at 25 yards the lighter ones (who knows why) group 50% better at 55 yards.
I have a friend who shoots Field Target witha 6.5fpe (NOT a typo there) airgun, all the JSB pellets did well up close but at range one was a clear winner, that would be the one to use.
 And if anyone isnt hip Brad has some nice clalclators :

 but I think that is a different subject?

 Let us know which works best for you at long range.

To what ever distance the gun/pellet combination shoots flat... then use mill dots after that...

MDR 840fps w/21.1gr Kodiak's  40yrds sight in From 8yrds to 45yrds never over 1/2" up or down. That's real world at the range not some chair gun stats, how does a chair gun shoot anyway.good luck .....Franky

Franky, just put your #'s into the chairgun and guess what?......it's right on the money! from 8.6 to 45.1    1/2" up and down. I found that chairgun is a great reference, good BASE for your real life shots. BTW if you're shooting 75 yds you should hold over 4 dots on 16x magnification...

Preez, Thank's for that info on 75yrds. My shots were from 1 pc. rest covered  bench only vertical measured. You need a grandson to move stand about 2-3yrds at a time to 45yrds.wanted to go father but  ran out of Help.What was it at 100yrds (drop) .Did they do tests or just math (chargun) I was not a believer maby thier right and I wasted My time.Fun anyway w/Charlie 10yrs young.....Franky

Chairgun is for those of us who don't have 10yr old grandsons yet.... or 10yr old sons for that matter. Anyways I believe it is strictly math with compiled pellet weights and ballistic co-efficiency. It's fun to tinker with. At 100 yds you'd have 8 mildot drop at 16X magnification or 6 dots at 12x magnification. Chairgun can also give you inch or click values for all those distances.

I sight in at 60 yards. I learn my hold over / under for 10-50 - 100+. The SR12 reticule on my Hawke scope comes in handy.
