I cannot find the formula for calculating tunneling for the life of me. I know I've seen it before-can someone post it up please?

Edit***
Is it
Max fov/min=x
Erector/x=y
Y*base mag=min mag where tunneling begins?

I recently purchased a 6.5x47 Lapua and took it out Friday to test a few loads. This was brand new Lapua brass, 140 GR Berger Hybrids, CCI 450 primers and H4350. All shots were at a 100 yards. I did fail to record velocity on 3 shots so I didn't include the ES or SD on that group. I didn’t have any pressure signs on the brass so I am tempted to go a little higher just to see if there is a node around 2800 FPS.

The rifle is a Defiance action with a Brux 26 inch barrel bedded into a McMillan A6 stock.

Last but not least, from group 5 on I was able to put 3 shots touching or in the same hole and then I would start to struggle and the next 2 would leak out. I am not sure if it was because I was just so excited to be shooting my new rifle finally or because I was on a time crunch due to my Dad needing to get back home to do his irrigation.

Interesting read! Who knew?

For those here that are well versed with the smoking of meat- I've got a Weber SMC coming this week and it'll be my first experience into giving this type of cooking a try myself (although I am a longtime fan of the end result). So as mentioned- I've got a SMC coming, approximately 70lbs of Kingsford Blue Briquettes, as well as Hickory/Cherry/Mesquite/Pecan/Apple Wood chunks.

I've been reading through various online articles and watching YouTube videos over the past week and it sounds like either pork butt or chicken thighs is the most forgiving for starting out and I'm leaning towards starting with the thighs myself. I think I'm good with the importance of maintaining temperature and how to do it (I also have a Termopro temperature gauge in the order with two probes, one of which I believe is best served to use one to monitor the ambient temperature at the rack with the 2nd being used to monitor meat temperature), understand the trimming of various cuts of meats, dry rubs, and marinating/basting timing. If I start with the thighs, I'm thinking of using either the Pecan, Cherry or Applewood for the first time (I prefer the heavy smoke flavor that hickory or Mesquite will impart but I'll likely have a crowd to evaluate how things turn out so understand the alternatives to be a bit milder/safer for a group.

I'm still trying to figure out the whole wet/dry brining element though as well as to understand the variations in smoking temperature. I've also seen some recipes where they put the chicken thighs in a pan rather than directly on the grill/arguments on whether or not to use the water pan (seems to focus more towards it being more favorable for the lower temperatures as far as I can tell but chicken seems to want to be smoked hotter than say the pork butt ... So many variables and I'm still trying to figure it all out.

All that said- for the Pit Masters here, any tips/tricks for someone starting out on their smoking journey that you'd be willing to share?

Sig Kilo10K Gen 2 vs Vectronix Vector X

I have owned the Vectronix PLF-15 and Terrapin X in the past and was impressed with both but much prefer binos to monoculars. So when Vectronix announced the Vector X I immediately put in for a pre-order. Got my Vector X last week and while I was impressed with some aspects, I was disappointed with others. Kind of long winded but here are my thoughts FWIW

First the positives. Optical clarity IMO was EXCELLENT. I would put them in the same ballpark as Leice Geovids (which are the best rangefinder binos I have had the opportunity to look through). Depth of field was GREAT. So nice to be able scan long distances without having to adjust focus knob.

But despite the excellent glass and great depth of field the Vector X were not without issue. There were several minor but annoying issues with them.

1) First thing I noticed was the focus knob is not smooth. Not sure how to describe it but kinda feels a little sloppy. Talking with others with the Vector X I found this was not unique to my Vector X.

2)Second issue was the Laser button. It is recessed and I found it hard to find the center of the button with my bare finger. I am guessing it would be very difficult to find with gloves.

2A) Also found the button to be very stiff requiring significantly more pressure than any other ranging binos I have used. Even when mounted on a tripod pressing the range button caused the aim point to shift slightly.

3)Another annoying quirk was having to depress the range button twice to get a range if the display has gone to sleep because the first press only “activates”the binos after the display goes to sleep.

4) Was excited to have an etched ranging recticle but found the SMR reticle difficult to use. You obviously don’t want the ranging reticle to interfere with your main viewing area but I found the reticle too far off center making it akward to use for spotting. Also could not get the SMR recticle and center cross hair to be in focus simultaneously (although that may be due to my astigmatism)

5) Lastly, although the binos ranged well, I did not find them to range any better than my Kio 10ks Gen 1 and they were a little slower

These issues may not be a deal breaker for some, but for me there were too many annoyances to justify the price.

Hoping to find a better solution I bought a pair of Sig Kilo10K Gen 2. I have had the Gen 1 for a while and have been reasonably happy with them. Almost bought the Gen 2 when they came out, but went with the Vectronix thinking the Vector X would be a better product.

Overall I am really liking the Gen 2. First off, I no longer see any blue tint. With the blue tint gone they appear clearer than the Gen 1. Not sure if they actually have better resolution but glassing with them is significantly more comfortable. Optically not as nice as the Vectronix but not far behind. So what do I like about the Sigs compared to the Vector X

1)Range button easy to index with finger and press without undo pressure
2)Fast accurate ranging similar to Gen 1
3)No need to hit Range button twice to get reading
4)New Wind buttons that are intuitive and easy to use
5)Ability to center aiming reticle on the laser beam
6)Lifetime warranty on glass AND electronics

Both are great units with pros and cons and not going to say one is “better” than the other. Depending on what is important to you will determine which you will be happier with.

Bottom line is that the Sigs check more boxes for me than the Vectronix and that is what I will be keeping.

Putting the finishing touches on my build. Only issue I’m having is that the magazine lips extend too far up and prevent the bolt from closing. If I release the magazine and hold it just a bit lower, I can cycle rounds through without any issues.

How do folks go about trimming magazine lips? Just flip it upside down on a piece of sandpaper and scrub ‘till it fits?

For the experts on here - do you guys figure out what COAL your chamber likes first, and then test powder loads at that seating depth, or do you pick your powder load and then test varying seating depths to dial it in? It doesn't seem like you can work on both at the same time - or can you?
