Logixtix, your plan is not a very good one. If you want to do everything with holdovers, there are some practical options, but using a second focal scope on a lower power than the retical is set for is not one of them. Too many stacking errors. If you are set on holdovers only, get a Horus on a fixed or first plane scope and be done with it. Or learn to dial.

9mm for me as well.

If your 930 runs why change? Have you tried an M2?

I can think of a couple of guys that I wished would start zeroing their rifles at 10 yards.

Someone post "the chart"!

My magic 8 Ball says it is a problem with your bolt. 10,000 is a good run for a bolt, pop in a new one and see if that fixes your problem.

Using the dot never worked for me, I think in terms of target diameters.

I used to zero limited rifles at 300, I now use 200. It does not really matter as long as you print some groups at all the ranges you will be wanting to make hits at.

Most matches are short action only 3200fps max. If you are going to shoot paper and steel for sport get a 6mm, if you are going to shoot critters and people get something else, I have no recommendation on that sort of thing.

Have you tried scotch? Enjoy a couple of fingers before you try a conventional buffer spring and reduced weight buffer. I do not think the Seekins bolt carrier plays well with the captured spring.

I picked one up for a new SBR that is still in jail. I have put it on a couple rifles to check it out and my feelings are similar to Kurt's. I have been a long time mini user, but this one may unseat it as my favorite dot.

The original question was what 18" barrel do I use and recommend. I have settled on and use two brands of 18" barrels, in 3 profiles. The first is a Seekins 18", it is fairly heavy, but is the most resistant to POI shift, it will make the hard shot before or after shooting the rest of the rifle targets. The other two are JP 18" barrels, the light and the medium. They both perform the same, really well, just not as tight as the Seekins, but they are lighter, and easier to shoot off hand. The medium swings and points the best for me, but the light is a close second, and amazingly enough is lighter. I am not as good a bench shooter as most of the guys on this board, I consider a 1" group to be pretty darn good at a 100 yards. My groups are a bit smaller when I cheat and use magnification, but even with a 3 gun scope they are not much smaller, I guess I am just not cool enough. A good shooting barrel for my money is one that can hit all the steel on the long range stage at the Ironman from the base of the slide with no more extra shots than where taken from the top of the slide (hopefully not many). There are probably a lot of barrels that are good enough to win with for our game, but these are the ones that I use. The whole "is it the indian or the arrow?" argument comes into play here, as a good shooter can do a lot with less than ideal gear. So I will recommend that you buy the Seekins barrel, because it is cheaper and Glen is a good guy, when you have just about shot it out, order a JP or a Black hole, and give one (or both) of those a whirl.

I would certainly hope you are not actually melting, if you are then seek help immediately. My post was just a tad sarcastic. I was attempting to poke fun at the 16" rifle fad, and at the same time take a swipe at the jousting lance shotgun tubes. I should not have even included the bullet weight stuff, that debate is not even funny anymore.

Not just BC. Velocity and recoil also matter. Higher BC, Faster, and with less recoil, but at the expense of shorter barrel life.

Unless it was magic.

Harness the evil! Use it to crush your enemy, driving them before you and cause the lamentation of their women.

Many of the selections are pure personal preference. Many people may disagree on individual options of a build, and there is no "right" answer. Here are my thoughts on your question, for what little good they are. I like the RC hand guards, especially since they added the knurling, longer is better, with just the comp sticking past. Only two optic choices for me, Aimpoint micro, or Trijicon MRO. For me the forged upper is better. It is lighter, and I am not such a fan of the side charger. I prefer the UBR stock, it is heavy and balances the gun better, and is very solid. As for grip I prefer to sand and stipple a stock grip to my tastes, or sand and add grip tape. Good luck!

Hook sling to the toe of the stock with a QD. Use a HK hook on the other end and a loop of 550 cord. Put loop of cord around mag tub, secure with tape if you wish, shorten sling so it won't reach end of tube.

A little hockey tape can be a real help.

rockset and a pair of wrenches, or if your prefer red loctite.

Great question. I'll see if I can get Russell Phagan to answer that one. I'm not sure off the top of my head.... This is what I THINK it is... For the MGM Ironman match the shooter will have one ammo can in which they may store extra ammunition, spare parts, spare firearms, food, etc for re-supply during the match. Shooter will provide their own ammo can which will be a Tall .50 BMG can (7"x12"x9") or smaller (less than 756 cubic inches) adios, tg That's correct. I can't remember what years, but we did have even larger cans at some point, but the dimensions posted on the match site are what now stands. Last year there was some confusion and some people had the regular 50 BMG ammo cans, and some had the taller cans that we used to use. I just wanted to clear up any confusion and be certain that everyone was on the same page with what size the can was supposed to be.

Kurt, you pulled another gem of wisdom out, rolled it up and hit us (me) on the nose with it. I feel shame now for wasting time with pointless argument. I was just attempting to fill a slow time at the office with some argumentative discussion. I apologize and concede to the wisdom of the group.

Chuck, I am not going to go googling definitions for the word illegal. I don't think I need to debate with you that the most commonly accepted use for the word is in the context of "against the law", and not the far more esoteric application "against the rules of a game". There are many words that have multiple definitions and could be used in situations that they where not the best fit. This is an example. A similar but more inflammatory example would be using the word gay to replace cheerful. By the dictionary it would be a correct use, but by the most commonly understood meaning it would not. Calling a rules infraction in a game an illegal act is grossly overstating the importance of the game and at the same time lessens the importance of those acts that are truly illegal. I am certain that you have an image in your mind of a USPSA RO. Now imagine that RO yelling "illegal!" and pointing at you when you step outside the shooting box.

Gooldylocks, thank you for putting me in my place with your quick wit and excellent copy and paste skills. Your defense of the word illegal in this context was stunning. But help me out, how exactly am I wrong? Do you not agree that in this case "contrary to the rules" would not be more accurate than "illegal"? The trigger at the heart of this thread is a legal modification to a rifle. The issue arises when that legal trigger is used in a game where it would appear to me to be contrary to the intent, and possibly the letter of the rules of many games. The use of the trigger in it's "binary" mode during competition would make it a rules violation, but terming it illegal would imply a violation of law. From the tone of your post it seems to me you have more to say, lets hear it!
