[5.56 case length]

There is a max length and then a trim to length.

1.76" is the max you want. 1.75" is the length you trim to so that as it grows that 0.001, it is still ok.

So the magic question is, how long are they ?

A *quick* check of 20 of them this morning 9/8/12. Most 1.764". A couple a little longer 1.767". A couple 1.687"

For plinking what's wrong with .005" over?

I can trim them, but want some compelling reason to do so......

*** Edit....

Just called Dillon. There is a compelling reason. If the case is too long it will extend into the rifling causing the case pressures to be too high.

So my next question was: Since I don't care about accuracy for plinking can I undercut them 10 or 15 thousandths so they maybe I can get a few uses out of them without having to trim them every time. They said yes.

Any reason I shouldn't under cut them? (remember... this is just for plinking).

If you trim them too short you will lose neck tension and your bullets will get pushed back inside the case. (Ask me how I know lol) Don't do it. There are reasons the specs are 1.750 to 1.760. Get a dillon auto trimmer and run it each time you reload. Thats what I do and its fast.

Pat,

what do you think with regards to the RCBS X DIE, as per instruction,initial trimming is .o2 from max lenght which is 1.740. any opinion on this

[1Lower-1BCG-2upper]

Jetracer,

thanks for the replies, any chances it will affect the fit of the rifle in general from switching back and forth. thanks

[1Lower-1BCG-2upper]

Hi,

Need your advice and opinions with regards to this set up,

Contemplating of buying a complete upper to alternate with my 16inch bbl upper, thinking of getting a 10.5. I know its not the best alternative for a 1911 to have to 2 slides with 1 receiver, but how about an AR, will it affect the original fit of the origianl upper?

One more thing, how about using 1 BCG for both uppers. I will eventually will get a separate dedicated BCG for both uppers, when the wallet permits, thanks

[Ar Brass ejection]

lol, it took me 10 months to complete this rifle, funds are very limited,kidding aside, I used the sprinco action spring based on my buddys recommendationed, maybe would try to used the Vlttor spring, my rifle is not a safe queen, fired almost 500rnds in a month, just doesnt like the marks on the gun. thanks for the replies.

[Vltor A5 vs. Heavy carbine buffer]

I am also using the A5 kit, but I replaced the action spring to a Sprinco green coded, but everytime I used a 5.56 round the ejected brass is hiiitng my forward assist housing, which causes some marks,I dont like beacause its a new Noveske rifle, will Installing the Vltor A5 spring solved this problem? By the way, with a 223 round, the ejection angle is more on the 3 oclock to 4 oclock angle which is just perfect for me, your feedback is highly appreciated. thanks

[Ar Brass ejection]

Hello,

My midlenght 14.5 Ar ejection of the brass especially the 5.56 rounds to 5 Oclock angle, not so much with the 223 ammo, in fact its ejecting at a 3 0clock to 4 oclock. Right now the ejected brass is hitting the forward assist housing and causing some scratches , which I dont like because this is a new rifle, just got it a month ago.

this is how my rifle is set up,

Vltor standard A5 kit , but replaced the action spring to a Sprinco green spring , I still have the vltor spring that comes with kit, should I replaced the spring back to Vltor and maybe a heavier buffer.

thanks

[Issue with light primer strikes]

why not try a factory ammo with different brands so you can start eliminating some possibilites of the problem.

[9mm major with hybrid barrel or poppel holes]

I for one was very hesitant to put the holes, its the fear not to make major with nine, but sometimes you have to take that risk. My setup is a flashback of the old power factor of 175. well it works for me.

[9mm major with hybrid barrel or poppel holes]

it started with a Millenium titanium comp,unfortunately it cracked, tried the bedell comp,although it shoot flatter but the recoil still hits on my hand , thats when I decided to put a hole in the bbl. Because I have a spare EGW comp(0n the Pics) we decided to try using . this time it shoots more flat with a little slap on the hand, the last port on the bbl. improved the recoil. I just mentioned the comp aspect,dont forget about the spring and load combo. finally it shoots softer and flat. with Vhit. N350 and HS7, I am lucky that my smith is very accommodating.I guess everybody has its own setup and concept on an open gun. I can never be more happy of my setup right now.

[9mm major with hybrid barrel or poppel holes]

infinity38s45 My smith drilled the holes, but it started with no holes, its a R&D lol, then drilled the one then another hole, in fact this is my 3rd comp. finally found best of my liking. Roger Kotanko built my gun, By the way, The Omega P.O. is more accurate then my gun, +3sec./month. thanks

[9mm major with hybrid barrel or poppel holes]

8.3 of HS6 and 7.0 of WAC both make the same Pf as above, but for now its the VhitN350 shoots the softest and flat., a buddy of mine who shoots STI MM, also find the N350 better for his gun. I should be okay with HS7 in the next 3 years, was able to stack for about 20lbs.

[9mm major with hybrid barrel or poppel holes]

This is my 9major set up with bbl ports,

Schuemann Hrbrid 4 port 2 machine, holes size 3/16,9/64, with EGW COMP 6CHAMBERS 4 TOP ports,4 side ports, Projectile-Zero 125c, OAl 1.175, Powder HS7 9.8GR. pF 173, Same spec as above but with Vhit N350,7.5gr. PF 170.. The 7.5gr. N350 shoots softer, Flatness are almost the same. By the way, I am using 8lbs of Sprinco and ISMI recoil springs and 17lbs main springs also from ISMI

[Akai comp/ Azone]

I had the chance to talked with Mr.Dave Pruitt, For Azone Comp he recommends 3 hybrid ports on N350. Thanks Mr. Pruitt.

[Quinn 2 cmore mount]

I just ordered the New OFFSET CHEELY MOUNT, cant wait for the Quinn2, and I wont pay the Brokerage fee.

[Quinn 2 cmore mount]

The tax in Ontario is terible 13% plus the Brokerage fee, it will be $200.00 in my door..

[Quinn 2 cmore mount]

I prefer from the U.S., Double A only ship by private shipping company, they charge more plus brokerage, USPS is much cheaper. thanks for the replies.

[Quinn 2 cmore mount]

Hello,

I cant seem to find a dealer for the Quinn2 mount,can anybody please point me to dealer, tried the Quinn site, still out of stock, thanks

[Freedom Gunworks]

On an earlier post of mine, I inquired about Akai , I dont want to put this 2 builders in one post to avoid builder loyalty, I know this 2 builders are both top notch. So my qustion or inquiry is about experiences of B Kiegan/Freedom 9mm major open gun. Again my thanks for all your inputs.

[akai open guns]

will give him a call anytime soon. for the time being, Im looking for someone who can facilitate the importation. thanks

[akai open guns]

I am shooting right now a full size 9major, with a schuemann rib bbl. I just switch from a midsize 38super. I"ve been shooting open since the 90"s , and they are the old power factor of 175. Personally, and in theory I beleive the supers is the ideal for an open caliber, but its the brass that let me switch to 9mm major, that the reason I am posting this quwstion to ask you guys your experience. caliber/ models wise,
