barrel length

I have two rifles that I’m feeding. Both are 308 Winchester. Both are 1:10 twist rate. Both are bolt action. But one of them (mine) has a 26” barrel. The other (my brothers) is an 18” barrel. I’m wondering if more velocity could be gained by using a bit faster powder in the shorter barrel. I’m...

Thought I'd share data results from some testing I did with the Nosler 240 JHP, 23.4 grains of H110 in 1) Ruger Super Blackhawk, 5.5 in barrel, 2) Ruger Super Redhawk, 7.5 in barrel, and 3) Marlin 1894 Dark, 16.5 in barrel. I was using clear ballistics gel so I'll include penetration depth...

I will preface this by saying that I've had the Glock 40 on my list for too long and that before Double barrel Joe wins I have decided I need to get a 10mm now before it's too late. What's kept me from buying the Glock 40 is it's $700 and Glock 20's can be had for quite a bit less used. What's...

Those who often reload probably know there are around 5 to 8 different manufacturers of smokeless gun powders, who all together produce nearly a hundred different types of smokeless powders, if not more than that. The powders they produce range from very slow burning (magnum) to very fast...

I'm building an 5.56 AR pistol, and I'm planning on putting a 10" barrel on it, mostly because I can use a carbine length gas system, and a regular buffer, etc. Are there any reasons why I should go with a shorter or longer barrel? What are your guys experiences?

I just got a PTR 91 squad carbine model with the 16 inch fluted bull barrel and I'm not sure the twist rate on it. None of that information came with the gun as far as I know. I tried looking it up. I believe the 18 inch barrels have a 1 in 12 twist and the 16 inch barrels have a 1 in 10 twist...

For general target shooting at the range, lets say 20 yards to 50 yards, what is your preferred barrel length and weight for a 44 magnum revolver? I am going to exclude home defense, carry and long range shooting as barrel length preferences will probably change for these purposes. Do you...

I am rebarreling a rifle in .300 RUM. This is the first time I have gone down this road so a couple of questions for the collective. The purpose for this build is to get to the 1 mile, and 2,000 yard mark, so heavy fast moving bullets will be in order. Will a standard 1-10 twist work with the...

Tikka offers the T3 chambered for 6.5x55 in both a 20" and 24" barrel. Obviously the longer barrel would be preferred for long range work (600 yd. & up). But what if the 24" tube is not available, and you're stuck with the short barrel? How much MV would I expect to give up? Would a heavier...

Good evening! A while back, though not too long, I started a thread about pistol vs carbine. I also promised to include data when I worked it up. You can find the original thread here: http://www.thehighroad.org/showthread.php?t=810127 Anyhow, I actually got somewhat higher velocities out of...

Good evening: I just want to see if anyone out theremay be trying what I am attempting. I just purchased a TNW Aero Survival Rifle in 9mm. I've only had a chance to try it out at my indoor range, so haven't had a chance to chrono it yet; But I have some good data on several loads for 125 gn TCN...

I have been shopping around for barrels. These are all the same part number barrel. The first time I found/saw the barrel it was listed as 16.5 inches. Then a few weeks later I go back to the same website to buy it and now that barrel is listed as 15 inches, then on gun broker dot com the same...
