    Ruger 10/22 “M1” Carbine. The ultimate WW2 cosplay rifle? Feel like storming the Normandy Beaches or planting the flag atop Mount Suribachi? You can make everyone’s favorite 22 look like the WW2 classic M1 carbine. I was looking for a non-laminate wooden stock for my Ruger 10/22...

    Measuring Muzzle Velocity Standard Deviation - Are we doing it right?

    My issue is the nature of sampling a random variable. This is not a problem that can be circumvented through technology or methodology. There is a theoretical limit to the information the Math provides. I ran 100 mini mags through my 10/22 and the result supports the notion that muzzle...

    Measuring Muzzle Velocity Standard Deviation - Are we doing it right?

    You have to shoot thousands of rounds of ammunition. The chi-square test factors in the sample size. As long a you shoot 30 or more, the central limit theorem kicks in.

    Measuring Muzzle Velocity Standard Deviation - Are we doing it right?

    It matters because the loader was making decisions based on these numbers. Accuracy in a load is a product of consistency. That required measuring. Manufacturers can do extensive testing to make their loads consistent. People that load their own don’t have that luxury. I ran this...

    Measuring Muzzle Velocity Standard Deviation - Are we doing it right?

    I actually used a chi^2 goodness-of-fit test. If anyone is curious, they can look it up on YouTube. I didn’t want to make a math lecture. I just wanted evidence to support that muzzle velocities are normally distributed. That makes computing the confidence-interval estimating...

    Measuring Muzzle Velocity Standard Deviation - Are we doing it right?

    I was watching a Youtube video where the OP was doing some load testing. He fired several 5-round groups while measuring the muzzle velocity, computed the mean and standard deviation of that random variable. He presented the results proudly and was moving to make a conclusion about each...

    Looking for ammo for friends wife new rifle B-day gift from in-laws

    From what I’ve read, resizing 308 to 7mm-08 is not complicated.

    22LR Target Ammo testing - 5x5@25

    I’m trying to come up with a standard method for measuring the consistency of guns and ammo. I decided to measuring the average group of 5 groups of 5 rounds each at 25 yards. I decided to 25 yards so my open sights rifles can also be measured. Groups are measured center-to-center. Today...

    Deer sighting, I 95 NJ

    We get deer at the range often. Lately, we’ve been overrun by turkeys…

    Deer sighting, I 95 NJ

    We ran across this buck while hiking in the Shawangunks. I actually have permission to hunt here. We got pretty close. The deer moved about 5 yards from the road behind some brush and came back out to continue feeding after we passed. Spring deer feel no pressure.

    Deer sighting, I 95 NJ

    This crappy video is from the dash cam in my Toyota. I’m driving back from work last evening on I95 north through Secaucus NJ and there’s a herd of deer on the shoulder. All that meat is just walking around suburban New Jersey. No Justice.

    Many of the firearms in my collection serve practical purposes. Hunting rifle, target rifles, defensive rifles… One is just a grown man’s plaything. The Henry H001 lever in 22LR. It stands in mostly factory configuration with only a skinner barrel sight and large loop as modifications...

    Always the Quiet Ones - Benjamin Marauder 22 PCP air gun

    A statement that is trivial, since the consequence is always true.

    Always the Quiet Ones - Benjamin Marauder 22 PCP air gun

    I got a hand pump. But, it only took a couple of trips to the range to convince me I needed a compressor. I bought the cheapest Walmart pump I could find still capable of 3,000 psi. It’s not fast. But, it’ll service a single rifle.

    Always the Quiet Ones - Benjamin Marauder 22 PCP air gun

    My most recent built is a rabbit hole that ending up bigger than the original plan. Usually, around my birthday, I think about purchasing a new rifle. The lack of available ammo made adopting a new caliber problematic. I was also looking for a more quiet option for small game. I considered...
