How is it demanding on the equipment? Serious question as I don’t know about that sport and can see it being demanding on the shooter being slung up but not so much on the equipment. What’s their round counts in a match?

My reason for the questions were in reference to the comments about 700 triggers whether pins or hangers, in PRS we shoot in the rain, extreme hot or cold and many times in very dusty conditions where dirt/sand is literally blown on and in the open chambers and the rifles will shoot without problems for a 100 shooters and 100 rounds or so in a match. That tells you in real-world applications that the current trigger systems work extremely well. Add the fact that there are roughly 365 matches a year in PRS rimfire alone now add NRL 22 and centerfire and you have a number of rounds combined that I think dominates any shooting sport. All with very low problems. Do triggers fail on occasion, yes, but it is very small for the sheer number of shots taking place.
Ahhh, my mistake. I thought it was in reference to demanding in terms of more precision. I will see myself to the door…

What did you do in the reloading room today?

The 3 way cutter was not being discussed, but might as well... there are additional cutters in the 3 way...but they still can leave a tiny burr, more pronounced when the cutters dull, and the angle or champher is cutting very little on the outside edge or just rubbing if shallow enough angle so less burr is noticed, because less pressure and little to no cutting is occurring at that spot, and one may see or feel a slight burr on one side because of runout, or out of roundness of the of the caliber hole in the case...as nothing is perfect.

Even form tools can leave a burr, with the whole profile being cut at once.
The pressure of the cut can flex the part being formed enough to allow incomplete 100% coverage between the part being formed and the form tool, a small burr will form.
Slightly dull tools or chatter can cause problems.
Thanks for your reply. I was looking for your more knowledgeable input.

I found the 3 way cutter head, like the one Giraud employs, can indeed leave a burr on the OD of the mouth when cutter position is not set up properly. . . AND when the cutter is dull. While I never experienced this my Giraud tool, I did experience it with the Trim It 2 that uses the very same cutter head design. With the latter, I kept getting a burr on the OD of the mouths and tried many adjustments trying to get rid of the resulting burr. I even changed to the different cutters on the cutter head and still no joy. Finally, I ordered a new cutter head from Giraud and put it into the Trim It 2, adjusted it and it worked perfectly. I get no detectable burr any longer. . .
. . . though I haven't used a microscope to see if there's really a microscopic one there. ;) :p

AAC ammo grenading rifles

I have shot probably 1000+ rounds of their 300 BLK subs and supers (both with cans) and have had zero issues. I did some velocity testing with three different barrel lengths. Let me see if I can dig up the link.... :unsure:

Gunsmithing Muzzle brake ruins muzzle crown

I'll say it, I'm skeptical. I've seen barrels with a muzzle device that'd have a crown get caked up with carbon, I've seen corrosion too, but I can't say that I've seen, experienced, or heard of a muzzle device causing any kind of gas cutting at the crown in so few rounds. You said that you removed the brake, re-crowned the muzzle and now it's back to its old self again shooting 1/2 MOA. Does that mean you shot the second 1/2 MOA group without the brake after the crown job? If that's the case, isn't it possible that the muzzle just had some carbon fouling on it and it didn't like having a clamp on device at the end?

I'm not saying that you didn't see a UFO but without pictures this largely becomes conjecture. It is a cautionary tale in muzzle devices though.

Dillon 650 Setup Confirmation/Advice

That's interesting, since I know the .300BO powder drop definitely goes into the ID of the case mouth (I ordered an Armanov one IIRC, because I didn't want to pay for a complete conversion kit when all I needed was the drop tube and the plastic case feed adapter, since I already had the .223 conversion kit).
Here’s a pic of the inside of an Armanov one I have it might flare it somehow but I can’t see anything that would indicate it’s indexing the drop inside the case.

Help me pick a chassis for a B14R Heavy

It’s not a trend in my case. The B14R comes with 18” and 20” heavy. I bought a 18” years ago. Shoots very well. I now bought a hvy 20” model from battlehawk. The price they sell for is worth the $$ in my opinion. I’ll shoot the two against each other and whichever shoots worst (unless they both hammer) will get a barrel upgrade from Modacam or I’ll pull the trigger on a Rimx or something

I’m buying this chassis with the idea that I’ll have a 24” tube or similar in it eventually.

My 18” factory barrel put 29/30 shots inside 1” at 100 yards the last time out with SKLR. Which is why I rolled the Bergara dice again.

We’ll see how it plays out. I shoot mainly prone so balance won’t be a major issue for me but I do like to train with at least tripod shooting as well.

I don’t think the Matrix Pro II will leave me “wanting” after this. The barrel swap can fix the balance issue. I’d spend half what a Modacam barrel would cost on weights if I kept the factory setup so it’ll have to be a hammer. But I’m willing to work with it if it is

Even after the barrel swap, you’ll still need to add weights if you desire the 4” balance point. If it’s just prone and tripod shooting, then it matters much less. I run a Pro2 and love it.

Tikka T3 Thread

I bought a t3x lite 300wm - then found the mag is only 3.350 shorter than even a sav mag. I read through some post here on aics mags and bottom metal where you cut the trigger face down and notch feed ramp -or not- to get to 3.500- sav mag length. which is still too short imo. maybe I didnt read enough post or misunderstood - is there no other options ? if not I may sell it without shooting it and move on back to Remington. any advice appreciated tia

Seeing a 22lr in flight

What does it take to see a 22LR bullet in flight? I was shooting today at 200 and 300 yards and do not believe I saw any bullets. I know I've seen them in the past but did not see any today. Do I need better lighting, better scope or better eyes? Today it was overcast with a few quick showers shooting center x. Scope is a razor G3 6X36 on 36 power. The berms are grass and dirt, targets are smallish white steel. The 4 berms are 50, 100, 200 and 300

And much to my surprise. I shot a group at 200 before the rain started in pretty hard. Then shot another group. Same size same position. How is that possible? Rain drops don’t affect the bullets path or the bullets squeezed between every drop for 200 yards?
