    Advanced Marksmanship Zero from bench is different to zero from prone?

    Another question to the OP: So, when you go from bench to prone and have the shift in POI, are you able to shoot the same sized groups? In other words, regardless of the shift in POI, is your shooting otherwise consistent enough to shoot same groups? Some folks who don't invest enough time to...

    Advanced Marksmanship Zero from bench is different to zero from prone?

    SAP: You are probably on to the correct theory on whats wrong. A 3 mil change is huge, and I normally anticipate a change of 0.5 to 1 moa from bench to position shooting, so I think there is something else. There WILL be a slight change in POI when changing positions. Your head and eye...

    125 grn. Speer TNT's / .308

    I found the Speer 125 TNTs to be fairly insensitive to seating depth and powder. I'd shot it out of a NM M1A Krieger 1:11 and Krieger barrelled Palma gun with 1:13 twist. I used IMR 3031 since I had some around and a little faster powder for the lighter bullet is more appropriate. Anyways...

    M1A Keeps Grouping Vertical Stringing, HELP

    Re: M1A Keeps Grouping Vertical Stringing, HELP to the OP: 3 things come to mind 1. the load is too warm for the m14/m1a. 42 grn of Varget/RL15 does real well with 168 or 175 in my M1a and is safe for that action. The M118LR that was developed for the bolt guns had to be downloaded when...

    Do you still need varget?

    Re: Do you still need varget? ADI= Australian Defense Industries. Sad to say stick powders are all made else where. IMR Canada. RL(15), Norma Sweden. VV Finland.

    Sorting LC brass by production year

    Re: Sorting LC brass by production year They change the number on the headstamp die. Don't think the forming dies for the body/neck are going to be changed until they are worn beyond spec.

    Strange thing at the range today using IMR4064

    Re: Strange thing at the range today using IMR4064 FC 308 brass is notorious for being thicker/heavier, yet softer than any other brass around. The heavier brass will give a higher chamber pressure, along with the softer brass...you get the idea. Segregate the brass, at least the FC, as it...

    Muzzle Brake for the wife's rifle

    Re: Muzzle Brake for the wife's rifle If you can, have her try shooting an extended session with a muzzle brake before you buy one. My two kids, age 13 and 9 like shooting the M4orgery but hate the extra muzzle blast compared to my ARs with 20" barrel and no brake. Recoil with 5.56 isn't an...

    garand and a case seperation

    Re: garand and a case seperation Korean PS stamped ammo was better, not corrosive. The KA 75 in particular had problems with case head separation. Probably way undersized lot that year. KA shoud be generally regarded as corrosive and rifle cleaned accordingly after use.

    garand and a case seperation

    Re: garand and a case seperation KA ammo not exactly quality ammo. There were several vintages of the KA that was still loaded with corrosive primers so you may want to check that out and clean the bore/gas system out properly. Not really a big deal as the M1 all shot corrosive ammo in...

    What Alliant powder is close to H4895

    Re: What Alliant powder is close to H4895 RL15 works fine in the M1A. Its burn rate is similar to IMR 4064, which had been a go to powder for the heavier bullets (ie 180-190s) in the M1 and M1A for many decades when those guns were used in HP shooting. My M1A NM shoots the 168/175s better...

    Neck pain when shooting prone?

    Re: Neck pain when shooting prone? Boiler, shooting prone is very different than bench in regards to the setup of the gun, in particular the height of the bipod, the height of the sights/cheekpiece, and the relief of the scope or sights. If you're using the 9" bipod at full extension, the...

    4th day at the range and what I learned

    Re: 4th day at the range and what I learned Jhr: so it looks like you are shooting smallbore, not centerfire rifle? CMP is primarily about service rifle and pistol shooting, although they have been trying to expand the base with the "games" such as Garand, etc. The CMP rimfire matches are...

    Why so many pulled bullets?

    Re: Why so many pulled bullets? US surplus ammo cannot be sold directly to the US public, thanks to a law Clinton signed when he was president. But it can be torn down and sold as separate components i.e. pulldown bullets, brass, and powder. There was even a company here several years ago...

    Case Head Separation Lake City Brass

    Re: Case Head Separation Lake City Brass Two separate issues: for your LC 5.56 brass, use your Hornady (Stoney Point) gauge and resize to bump the shoulders .003" to ensure easy feed and extraction. More than .005" bump will overwork the brass and lead to premature case separations. I have...

    M1a reloading with R-15 / 175 smk

    Re: M1a reloading with R-15 / 175 smk BR-2 primers are fine, but it won't shoot any better than Wolf LRP in a M1A but cost half as much as the CCIs. I'd keep the CCIs for the bolt gun. Plus the Wolf is a real thick primer, less worry for slam fires in the M1A. BTW, 43.3 RL15 would be too...

    M1a reloading with R-15 / 175 smk

    Re: M1a reloading with R-15 / 175 smk 42 grn RL15 with LC brass, 175 SMK to 2.80" for mag length. Shoots better than the standard 168 SMK NM load in my M1A. Good enough to be in the top 15 at the M1A at Perry in 2010.

    Regarding Smokeless Powder Choices

    Re: Regarding Smokeless Powder Choices the .222 will like VV133 and probably 4895 and the .243 will like IMR 4350. Just saying. Agree with the 4831 for the 300WM
