I've really wanted to get a chronograph and play with my Hill bows with it. Problem is, every time I get a little bit ahead on money, someone offers me another bow, and I'm weak... I always go for the bow rather than the chronograph. Recently there was a thread on another list about chrono testing Hills, and the author, Frank Vaccarro, was kind enough to let me share his findings through our site. Here are his postings:

I am going to shoot the technohunt with a Howard Hill I just bought from Bob & will let you know about velosity as the technohunt chronographs each arrow. I have only shot about 30 arrows through mine, & haven't found any handshock. Frank
My bow averaged 151.2 fps for 30 shots with arrows averaging 569.8 grs five different arrows were used in the shoot they have huge round blunt points required by the technohunt. I'm wondering if they cause lower velosities. I will chrongraph them on my chrony with field points. My bow is 61 lb. It has no handshock at all, it's very comfortable to shoot. It also has no string silencers & is very quiet. Frank
Larry, your welcome. I will chronograph it some day with field points & see if there is any difference between them & the large blunts. Frank
Had to look back to find this thread, I chronographed the same
arrows I used in the technohunt this afternoon. I picked one arrow of the
5, it wieghes 574grs it has the large brass blunt & I got faster speeds
here in the backyard than in Uncle Bob's indoors. I averaged 164.6fps 2 feet
from the chrony 10 shots with a high of 165.9 & a low of 162.2 that gives
an extreem spread of 3.7fps I think my form is improving. The arrow I used
today is a bit heavier than the average I took on all 5 arrows @ the technohunt
& still getting 13.4 fps more speed. I had the feeling all along that
the technohunt chronograph was a bit slow.
I also chronographed the same arrows with field points & got an average
of 170.8fps so I do think the large blunts do cost some velosity.
I also chronographed some whispering wind arrows that are split hex arrows
by Bob Burton (these are what I hunt with) they wiegh 659grs, I got an average
of 160.2 fps.
I hope I'm not too late with this data to interest some of those who shoot
a Howard Hill bow I had a blast chronographing the different arrows. Thanks
Frank
Timothy, You are welcome I had a great time getting the data over several
days.I'm drawing 28" Bob weighted the bow on his comercial scale &
it's 61lb@ 28" I have a handheld scale & get 60 lb. On my handheld
scale I'm kinda guessing as where to anchor using the scale,so am taking Bob's
measurment as the tue one. I have measured my draw length several times &
I get 28".
Shannon I'd really be interested in seeing what your 73lb bow is doing. I
was really surprised when I looked at this bow & actually drew it. It's
so smooth if you would have asked me what I thought it drew I'd have said
about 55 lb before we actually weighed it. I'm really having fun getting to
know it.Thanks guys these bows are really smooth & fun to shoot Frank
Larry you are welcome. I had a great time getting the data over several days. I really did suspect there was a difference in the technohunt chrono & mine. I have checked the chrony against a pact by placing the chrony on the rails seperating the sky screens of the pact & chronoed the same shot on both chrono's, the difference was 2 fps so I know the chrony is accurate. Frank
Dick, I would not mind at all. We need to remember though the results were for my bow being shot my me, & could vary on someone else's bow. Feel free to use the data. I looked at your site & enjoyed it. Frank
Dick there are lots of chronographs out there, I have a Pact
that's mid expensive & a Chrony that is mid low price. I use the chrony
most. This is the second chrony I've had. I use them to chrony rifle &
pistols too & the 1st one caught a bullet fragment & went belly up.
My Wife got me one for our wedding anniversary a couple years ago. Might put
one on the Christmas list. They start about $87.00. Mine is the archery model
with a artificial light setup so it can be used indoors. Any of the models
can be used for both archery & guns. I have even chronographed air rifles
on mine.
I know about the new bow syndrome Gotta have it gotta have it! Or boy this
bow would really be great for ................. insert treestand,ground blind,stalking,bowfishing,
well you know the story. I bought my Howard Hill from Bob Burton(Whispering
Wind Arrows) Bob & I went to college together long ago enough I'm not
saying,& have been friends every since. Bob sustained a injury to his
elbow that won't let him shoot right handed any longer. He offered me this
Hill at an attractive price. I had shot Mike Griffith's Hill & really
liked it,I shoot mostly Fox bows,& told myself if I ever ordered another
bow it'd be a Hill. When we moved to Montana I am 2-12 hours from the Hill
factory & Craig is a good friend of Bob Burton. Anyhow that is how I got
my Hill.
Please feel free to use the data I gathered the bow is a 66" ebony riser,61lb@28".
I draw 28",the bow is so smooth I'm having no trouble with the 61lbs,my
Fox bows are in the 54lb-56lb range. Take care. Frank
