turbo33 Posted September 19, 2013 Report Share Posted September 19, 2013 (edited) As its such a vile day and I can't go out and play I cleaned all the guns and checked through the ammo stocks. I have a some Winchester hmr which were dire in my 452, some Remington that were stunning . Some Remington 22lr subs which were nuppence a box, and the dealer said they were awful I found them ok and certainly on a par with the winnies, if not, fractionally better, some Winchester subs and some eley subs. The eleys were very good indeed, So thinking of the variable results, and having lost the will to live with the weather, I thought I would weigh a few and see if there was much variation. 10 of each went on the scales and measured in grains, live rounds. Re-arranged in order for ease of viewing. Ok I appreciate its not totally scientific, as I didn't have any empty cases to weigh. However, the results are interesting and I think it does go some way to explaining why some rounds work so much better than others. The consistency in the Rem .17 and the Eley .22 is very good and i'm sure its no coincidence that these two are the best I've tried through my rifles. With the HMR Remingtons, there was one that was some way out at 39.8grns I pulled another out of the box and that was 40.1grns. However,on the grounds of accuracy, I included it. But it does explain flyers. Were it not for that, the difference would have only been 0.1grn It would also explain to a degree, why the Rems were stunning through my HMR. rimfire ammo weights.pdf Edited September 19, 2013 by turbo33 Quote Link to comment Share on other sites More sharing options...
killer_pigeon Posted September 19, 2013 Report Share Posted September 19, 2013 very useful info there, that's the problem with factory ammo, and the mood of the machines stamping it out all day ! did you check the powder weights also ? ill bet they vary slightly also ill use your info as my excuse next time I miss with the Hmr !

Whitebridges Posted September 19, 2013 Report Share Posted September 19, 2013 The Remington HMR look very consistent. I'm going to get a box or two to try but always been very happy with Hornady V-max. Eleys subs also good. I've shot several thousand with no poppers or crackers.

That really would confirm me as certifiable As I mentioned, the Winchester HMR were awful. As I am going to have to pump them off at some point, I might just weigh out a few that are the same and see if they group more accurately than the random weights.

I've only ever used the Hornadays once. I had two boxes and they both had 35% of the rounds with split cases before they were fired. I took them back and the dealer sent his entire stock back to EB. No-one round here stocks them now, so I am unable to see how they compare which is a shame. Edited September 19, 2013 by turbo33 Quote Link to comment Share on other sites More sharing options...
dadioles Posted September 19, 2013 Report Share Posted September 19, 2013 It can be a strange geeky world.... welcome. I have not tried this with hmr rounds but did with .22lr which varied in weight within the same batch. Unfortunately when I fired them they did not do what was expected of them and they all shot to a similar random pattern no matter how I sorted them. My next step was to measure the cases and finally sort the bullet heads. None of it made any difference or showed any repeatable pattern. Finally I compared chronograph readings with where the shots landed on the target and expected faster bullets to hit slightly higher than slower bullets, fps varied from 992 to 1041 but the bullets did not seem to understand what that meant and all ended up in about the same place. Obviously what looked like a variation in speed to me meant nothing to the bullet and 2% variation is not much. I gave up and became normal again.

Normality has resumed and I will be out shooting tomorrow as a treatment for my condition As the condescending remark goes "I hear what your saying, but" over the 5 different rounds, consistent weight/accurate round.......inconsistent weight/inaccurate round.......chance and in order? If so, I'm doing the lottery Sat Quote Link to comment Share on other sites More sharing options...

If so, I'm doing the lottery Sat Always useful to have a quick look but only a snapshot and regrettably shows nothing. With all due respect that is statistically useless, the sampling needs to be FAR greater numbers and different batches as well to form any meaningful statistical comparison. And they may simply not like your barrels. Eley .22 are quite accurate in mine but no more so than Winchester, Magtech and RWS, and Remington subs are atrocious. HMR wise I'm not a fan of Remington either, Winchester probably edges it for me, but HMR wise ALL the 17g V-Max are so close it's not worth the bother.

Bewsher500 Posted September 27, 2013 Report Share Posted September 27, 2013 i was bored one day so sorted all my rimfire ammo by rim thickness (quite a variety as it happens!) couldnt for the life of me see any significant change in accuracy or group size of batches!!

kent Posted September 27, 2013 Report Share Posted September 27, 2013 Accuracy and hence sorting in any way is always limited by the weakest factor - it might not be evident if the gun or shooter cannot exceed the capability of the ammo Quote Link to comment Share on other sites More sharing options...
