    Geissele vs. Timney triggers

    Don't know about the Timney but I just purchased my second Geissele trigger. The high speed national match trigger for the service rifle. Been using the first one for our club matches for a few years now and it's the best trigger I have used. It's adjustable first and second stage. I have it...

    Varget anyone?

    After years of M1's and M1a's on the firing line...Just started to use my AR-15 on the line at our local 100yd matches. It's a BM lower with their DCM 20" upper with a 1:8 twist bore. Been using 52 and 55gr smk's with 24 and 25gr of N140 in FC brass. The N140 is difficult to get locally most of...

    Strange problem while loading .308

    Re: Strange problem while loading .308 Low power (electrical,battery) can cause just that sort of problem. Don't understand why you had normal readings for your standard load though. Or being close enough for muzzle blast to affect chrony. I'm usually at around 12 ft. from the muzzle.

    Need help with my CED M2 Chrono

    Re: Need help with my CED M2 Chrono I tested my first gen CED in the house with rubber bands. I will pick them up. So if it picks them up it's working correctly most likely. And the problem is out at the range. Just a thought.

    New 7.62 Nato Brass from Scharch (Top Brass)

    Re: New 7.62 Nato Brass from Scharch (Top Brass) Just compared the IVI to my new IMI. The primer pockets are .001 shallower and the ID and OD of the neck is .003 - .004 narrower on the IVI. BTW it does not have a Nato circled cross but neither does my IMI. I think the circled cross is the...

    Has anyone tried the new Canadian 7.62 Nato brass from Scharch (Top Brass)? If so what do you think of it? They want $150.00 for 500 cases.

    M193 80

    Re: M193 80 Thanks guy's. I was told on another forum that the 80 is probably 08 instead. It is if I don't rotate the case and read it. These guy's prob just bought the ammo at the gun store as new or fairly new ammo.

    M193 80

    Default M193 80 I just picked up some 1X fired brass at the range from some guys shooting next to me stamped M193 and the other side 80 which I presume is the year. They were shooting AR-15's. I believe it is 5.56mm but it does not say .5.56 or .223 on the case head. I have never loaded...

    AR15 loads bushi DCM upper 1:8 twist cabon barrel

    Re: AR15 loads bushi DCM upper 1:8 twist cabon barrel Short stick. Thats one reason I like it. CCI 400 are standard primers. Using a rest five shot groups are an inch and under at 100yds. I believe I'm .4gr under max. I bought a pound of N140 a while ago. Slower burn rate so maybe will push...

    AR15 loads bushi DCM upper 1:8 twist cabon barrel

    Shoots factory ammo just fine. But when I load 23gr, 23.2gr and 23.4gr of N135 for a 69gr SMKHPBT in a FC 1X fired case and CCI 400 primers the bolt does not go all the way to the rear, about 5/8" short of full open, even with a single round sled for slow fire. No ftf or fte. My plan is to load...
