You and me both brother. Shocking no one else sees it.
Please enlighten us on whats so shocking? Are you calling me a liar? Please, do tell all of us. Those groups measurements are lie? They arent outside to outside minus .223 like I said? Say what you have to say and back it up with some facts instead of making stupid ass comments like that. Those black circles measure .5" outside to outside for your reference. Here's a picture of a caliper on one of the groups lined up best I can without holding it and the camera, you can subtract .223 on your own so you can show everyone the liar I am. Some of you guys crack me up. Ill give back the prizes now. You got me. lmfao
Next time you call me a liar I wont play so nice.
No, NOT calling you a liar. But I do say your calculated measurement is incorrect. You clearly stated that the holes in that paper are 0.117" Therefore you should be subtracting 0.117" from your measurements not .223 to give correct value. Is that not correct?
Understand we are not competing for prizes. I do not question the targets and appreciate the info you have posted. But will have to agree to disagree about your calculations. Ontarget assumes .223 holes are .233 in diameter and that is why it subtracts .223" from edge to edge to get center to center distance. If holes are .117" for whatever reason, simple math states you must subtract .117" from edge to edge measurement to get center to center distance.
Out of curiosity, why does the bullet hole change diameter vs bullet diameter? Is the soft lead bullet compressed going through the barrel and shrinking it? Is it the elasticity of the target being shot?
I measure my targets the same way that you do. I am just curious as to why it happensThat I dont have an answer for you on. Im just stating the facts. I have 3 different target types here from heavy flooring paper, to printer paper to cardboard to thin butcher paper all shot with 22LR. the hole size varies on each
I just measured a two shots group where two bullets passed thru the same hole and the hole measures .174". Then I subtracted .223" for a group size of minus .049". Does that mean my center to center group size is minus .049 inches?
I've been a professionally employed engineer for over 32 years and work with a staff of engineers that develop very sophisticated consumer products. In my experience even cheap calipers are very accurate +- .001".
I have always measured edge to edge from the black circle around the bullet hole, then subtracted one bullet diameter. Measuring the hole will always be smaller than the ring around it where the bullet "wiped" the target. I think this is what some are seeing.
Absolutely incredible results however you measure these groups!
Thank you Padom and Orkan for all that you do! The information is priceless!
I'm currently experiencing the opposite, my Vudoo runs like butter, My Rim-X is sticky.
Humm, OnTarget methodology is distinctly different ... first it uses the nominal bullet size for scaling the circle you place around your bullet hole then you center this circle on your bullet hole - you DON'T position the circles so that they just touch the outside of the bullet hole (as you would a pair of calipers...So what your trying to tell me is a 22lr bullet diameter is fluid??? It changes from shot to shot, target to target, person to person?? I think not.. i can shoot my RimX through 4 different targets, cardboard, thick paper, computer paper and that hole is going to vary in size on each of those.... the bullet still is the same size shot in all those targets...
And OnTarget does not assume bullet hole size made in paper.. it subtracts bullet diameter....Jeff will tell you this if you reach out to him about how his software calculates... thats how everyone calculates groups by hand...they subtract bullet diameter. This isn't anything new. We can agree to disagree
What ammo have you tried? Multiple lot#s? Other things you have checked before changing the barrel?My RimX with an 18" Proof. It is accurate, but not where I would like. I've read through most of the thread multiple times. So what would be my best option for a replacement barrel, maybe a Bartlein, what chamber, who can supply it? Really like the action once I got the mags adjusted. Also have a Vudoo. Thanks guys.

i suspect, you don't really 'use' the numbers - i suspect you look at any group and instinctively know how it 'rates' ? i don't have that skill/experience yet so need the measurements to help me evaluate other peoples groups .
I don’t want to run a rim x just in case I like it better than my vudoo unless someone sells their bartlein cf rim x BA. Then I might be able toThe five* or so rounds I ran through it last week seemed nice. Maybe I need to cycle your Vudoo and compare it to mine.
*He doesn't like people touching his stuff. I had to twist his arm to shoot it. Hence only five rounds.

The simplest, precise way to measure group size is to take the two holes farthest apart in a group and measure outside edge of one to inside edge of the other. This gives the center to center measurement regardless of caliber. No subtraction of bullet diameter needed.
I don't think it's really about grease holes, caliper accuracy, or digital measuring apps vs by hand. I think it's about the fact that you can look at a group that measures .230" and there are .22 caliber bullet holes not even touching.
I believe the cause for this is some paper/ bullet hole error. I noticed this a while ago measuring my groups and in others targets that have been posted on this thread. As you're shooting the paper will fold inside and bullets will pass thru a hole that is formed by a portion of folded target paper and when you pull the target and fold the bent edges of the hole flat it looks much smaller than it was when you shot it. And there's no grease marks to measure.
I think this causes the biggest discrepancy in group sizes. And then you get a wild looking disparity like these two for comparison sake.

That's what I'm saying. It's sometimes a matter of perception. I've had to double-take some of my groups and some Ive seen on here. Both those groups have inside bullet holes that don't touch, yet somehow measure in or around 1/4 inch. That boggles the mind and that's what I think people are having a hard time with.
Head shots or center of mass?I also shot 5 flies on that stream
@padom Are any of the barrels for your Rim-X longer than 20"? I read your one barrel test thread of different manufacturer's 20" barrels, but just curious if you have tried any that are longer...
I suggest to call John directly and ask. I've a barreled Origin on order with him and he said yesterday that he has no control over when Zermatt ships the actions to him. Maybe he has a RimX in stock...Does anyone know current wait time on actions from Keystone Accuracy?
What barrel did you order?Keystone has yet to ship RimX barreled actions ordered April 20
not me.What barrel did you order?
