Firstly, you're not actually using a micrometer at all - you're using a digital Vernier calliper - they are not the same thing... You should really be measuring the bullets at their largest diameter, and you need to take the bullets out if the cases to do that. Bullets from different manufacturers will vary in their shape and the profile of the nose - the major diameter may well be inside the case and not necessarily the part that you can measure outside the case mouth,. The 'bullet in the muzzle test' is at best, a very rough guide.
You need to pull bullet and measure bearing surface to get accurate measure. British MkVII bullet is .311. PPU uses .311. Muzzle test isn't a good test due to varying ogive. How your rifles are going to shoot depends on bore and muzzle condition. If your bore is worn shoot 312 if muzzle is worn it may not like boat tails like ppus.
The most that video showed was difference in POI between brands. To determine whether the ammo performs as it should, you need to shoot a group with each brand. It "may" be that the Remington shot ok, but just to a different POI, and that can be remedied by zeroing. Having said that, I've measured Remington bullet diameter myself with their 174gr FMJ, and the bullets mic-ed at .3095.
@@harrynr32dn thank you for watching & your comment . After I did the video I realized that I should have done a 5 shot group with each brand . I know rifles will shoot differently with different ammo and bullet grain . Also that these are military surplus rifles and muzzle wear all make a difference . What I was trying to show was that the “ bullet test “ on each ammo was different . The PPU was at .311/.312 while the Remington was at some .308/.310 . So over all did it really make a difference or just the fact of POI for each one & have the rifle zeroed to which one you are using
You were measuring all over the place because consistency is key. Next time try measuring where the bullet meets the case, there would be more consistency at that point. You do realize that they have two different profiles.
Yes , I know how the British set their caliber standard and the U.S. set its standard . I was trying to be consistent of where I was measuring , although not precise , I wanted to show there was a different . I do appreciate your comment . I am always learning
The other day whilst loading a rather large volume of .303B brass, I got myself curious as to what would happen if I attempted to use .308 bullets in my No4. I have a partial box of Hornady #3090, a 220 gr RNSP. Using Ken Wsters' Pet Loads as a guide, I loaded up 20 rounds using IMR4350 in R-P brass w/ WW LRP. OAL length chosen was .3085 (long loaded a bit). Accuracy for my 70 y.o. non-bespectuled eyes was 2 inches @ 55yds. Sights set at 200 yds. I am guessing that long loading helped better to engage the rifling in this parallel sided bullet. More than acceptable for the pigs roaing wild in this part of Florida.
would have been interesting to see 3 to 5 shot groups done with each to get a better idea. Back when I was shooting an Enfield, the Remington ammo was all that I could find and I never had much luck with it. The undersized bullets sure could explain it.
After I had edited the video and released , I did think I should have a 5 shot group of each ammo & rifle to have a more comprehensive comparison . I was going to make one with 3 different Carcano’s I have , because I thought I had some older .268 ammo , I realized I didn’t , so that will have to wait
Ok , I can accept that . Some one else commented I should have done the measurements of the bullets at the top of the casing . Help me to get better , what else should I do or not do to gain experience in using the micrometer . Thank you for your insight and help to improve myself
its impossible to get a good measurement with the bullet in the case. take one out and measure above the boatail portion.The calibers you have will work fine.Good luck@@milsurprifleguy7091
@@milsurprifleguy7091 Those Chinese vernier callipers certainly are not a definite precision measurement tool . ( they should be fine to explain what your trying to explain ) You could measure the outside of the necks in a few different places, to check for consistency of neck thickness / Concentricity. Measuring the bullet diameter has to be done with bullets as a component / pulled from the case . Cheers
@milsurprifleguy7091 no problems mate. It's easy to become the worst person in the world, when one posts on TH-cam. Measuring is a profession & and an art . Skilled machinists love to point out flaws in technique & inferior equipment.
It is about Bullet diameter and your bore diameter. what you have done here is show everyone that if the bullet doesn't fit your bore, you will not get good accuracy, I cast bullets and slug my bore's on my Enfield's for the best accuracy and I get sub M.O.A., The British .303's are a wide net to throw when it comes to bore diameter. I also cast bullets for economy and having gang molds keeps me supplied with quality stocks of ammunition as copper bullets have increased substantially over recent years. Also lower pressures with lower powder charges equal longer brass life, I get good results out to 200 yards, Hurrah for me, No.. that isn't my point, It is about bullet diameter and bore diameter fit to get the best accuracy.

@@thorsaxe5881 thank you for your insight . I do know some rifles “ like “ a certain brand or bullet weight . I know especially with my Carcano’s they are a .268 and commercial ammo is .264 . I have my rifles for myself and would like to do the best that I can with them . I have not done any reloading or casting my own bullets .

Again thank you for telling me what you do to get the best results
Shot the smle, and the usual, but the cake was the 1895 Winchester Rifle well hell yes. 300 yd pie plates, Find the Britsh issue just too heavy, as the m1 and others arrived, remembering bores done in by cordite 303. Great video good to see.
Thank you for watching the video and your comment . At the moment I just have bolt action rifles/carbines . Except for a couple of SKS ‘s & one AK , with a recent acquisition of a AR -15 ,I don’t have any semi auto rifles , that will be anther chapter in my life to get into
