Using The Hornady Overall Length Gauge And Bullet Comparator

[kingrider75]

I have a question, I have a nine inch digital caliper that has a tad thicker jaws than most 6 inch sets. Is the body of the comparator made to accommodate larger size calipers as well?

Fantastic i've had this gear for years but reading the instructions were mind blowing "Thanks" one question though i have a Tikka T3 in 308 and a Browning 243 how do i know how far to back off from the O-give trial and error ?

[AccurateWayz]

@kevin01041961 you could to trial and error but i would look up the info some one could of already done the work for you. even tho your specs might be a fraction off at least it will get you close. Thanx for you comment!

Very informative video. I would like to use the comparator inserts to measure the shoulder (headspace) of my cases by using a 0.375" calibre insert for a 30-06 case. Will the neck fit through the insert or do I need to buy the dedicated headspace inserts?

Thanks!

[firetoy911]

Wow I'm glad I wasn't the only one confused with the seating calculations because it seemed like your bullet would be way off the lands..

[Thunderball66]

Enjoyed the video. I have always heard "O-give" pronounced "O-Jive".

Great vid, very clear.

Excellent!! Thanks for the instructions.

Thanks for taking the time out to do this video.

Sorry, but I can hear my Drill Sergeant now: "This is NOT a gun! A gun is a naval artillery piece. THIS is a rifle! Now drop!!!" Being all OCD and whatnot, thought you'd appreciate that stuff.

Great videos though!

Thanks for posting such detailed video. I have been scratching my head trying to figure out how to heck to accurately set my OAL when the tips of the bullets are different lengths and how close to the lands you can go? I will be running out to Cabelas after work today to purchase on of these tools. Many thanks

@AccurateWayz On my Palma rifle .308 my bullet is hardly in the brass and can be pulled by hand. But, I use the Lee Factory Crimp Die to secure the bullet so I don't end up with gas escaping back from the neck or the action full of propellant during competition. You might tighten your groups by placing a small factory crimp even without the use of a non-cannelure bullet.

excellent video series. answered many questions not addressed in other videos.

[kevin01041961]

My deepest thanks i purchased the oal bullet seater 15 yrs ago and omly now do i know how it works ! how do i find the jump head space for my rifle?

[stellbo]

Well done!

[AccurateWayz]

Unless I'm not understanding your question you should get the same number everytime you check it

[fishblade2]

my question is how many times to do you use the same bullet to check the lands and o give to make an almost exact average measurement?

[ryandpahl]

Nice video.

A little tip for seating the bullets. I used a sharpie to mark the top surface of the seating die with a line. This way I can watch the amount of rotation I give it. One complete revolution is about 0.060" of seating depth. Half turn = 0.030". This way you can measure once : 2.041" , turn in the die 1/3 of a turn or about 0.020" and you should be very close to your 2.021" final measurement.

FYI, ogive is pronounced O J eye v.

[Se7enMag]

great instructional video, might wanna mention that seating bullet onto lands can increase chamber pressures, just as a warning.

[Zookagold]

I don't think you seat your bullet to 0.5 inches before the lands. More like 0.05 inches, no? Look at the section where you are writing seating depths. You say average jump is .2 to .3, and you like .5. Left out a zero.

[AccurateWayz]

@Zookagold OOPS My mistake nice catch man! TY

[Zookagold]

@AccurateWayz Man, I know just how easy it is to drop those zeros, no worries. Thanks very much for that video, it was very instructive, answered all my questions, and now I will be getting the device! -Z

[fishblade2]

@Zookagold so should the .2-.3 be .02 and .03 instead or just the .5 should be changed to .05?

[Turbinecontroller]

Nicely Done

[MrConspark]

Very well made video and good to see a young guy can add up (do his math) these days.

I have since changed my use of my OAL gauge and comparator-I now zero the comparator properly when using

[phil656565]

@MrConspark Its funny how you mention young guys doing mental math, im in calculus III and our professor had us solve a rather complex problem yesterday, however we almost all were temporarily stumped on 52-38 haha. Access to calculators has made us forget simple math skills.
