wymberley Posted February 18, 2013 Report Share Posted February 18, 2013 Not such a great choice locally so no idea to be honest. Other than the CCI which were no good, can anyone suggest any brand which might improve the SD of two loads I'm playing with for the 22 Hornet. At the moment it's still a quagmire here so am trying to tighten up the SD using the chrono' on the grounds that this may well produce better/consistent groups once we are able to get back out in the field. Not interested in any increase in speed as such. Cheers Quote Link to comment Share on other sites More sharing options...
rarms Posted February 18, 2013 Report Share Posted February 18, 2013 Are you sure primers will make a difference? If you think they will, remington make some. Quote Link to comment Share on other sites More sharing options...
wymberley Posted February 18, 2013 Author Report Share Posted February 18, 2013 Are you sure primers will make a difference? If you think they will, remington make some. To be perfectly honest, no I'm not. For months now we've been grounded so I'm reduced to fiddling to relieve the boredom and fight off the withdrawal symptoms. Am taking the opportunity to try a new load and have plenty of time so trying a couple of different primers will be helpful. On the grounds that CCIs made things worse, an alternative might reverse this. I simply know not but it's worth a go. Quote Link to comment Share on other sites More sharing options...
kent Posted February 19, 2013 Report Share Posted February 19, 2013 I found differences but still not happy with the SD, accuracy is great though so not quite sure why I am bothered what the chrono says. I actually think SD is the weakness in LIl gun not so much the primers ( I improved it but not so sure I will ever make single figures ) - but it shoots well with low pressure and long case life. I am constantly messing but the SD just wont come down to that of other calibres Quote Link to comment Share on other sites More sharing options...
Amazed Posted February 19, 2013 Report Share Posted February 19, 2013 I was reading a paper in gallery loading done back way when. To cut a long story short the out come was to gain a more stable ignition by boring the flash hole out to 38 gauge ( must mean wire gauge) In a different one it said to be wary of using a too powerful primer in the hornet as the short case can be seperated befor ignition of the main charge. Some things to look far tanyway Quote Link to comment Share on other sites More sharing options...
wymberley Posted February 19, 2013 Author Report Share Posted February 19, 2013 Thanks, Guys. Yep, I found the Winchester WSR primers to be far too fierce giving problems on what should have been a well safe load. I tried the CCI small pistol which were erratic. Am using the CCI small rifle at the moment which produce excellent results except for this one bullet in the one rifle (over the chrono'). However, Kent, I think you could well be right as what you say bears out what I've previously encountered. I went out yesterday to poop off another couple of loads and noticed some improvement in the ground from several days earlier. XC is predicting no rain (to speak of) and a fair blow from now until at least next Tuesday so perhaps I'll just try the batch I've loaded ready for today over the chrono' and then load a few of the most promising looking couple of loads and if the conditions continue to improve in the field, check the grouping and see what we get.

kent Posted February 19, 2013 Report Share Posted February 19, 2013 If you run a Lil Gun load over the chrono as you work it up you find exceptionally high results at the low start loads but a lot of variation, these spikes in velocity can equal what you end up getting at the top end.

wymberley Posted February 19, 2013 Author Report Share Posted February 19, 2013 Well, I shouldn't be too surprised as this bullet is the one I mentioned about a year back achieving a SD of 10.3 in the Ruger, but an extra 0.1gn has got me down to 21.5. With the Ruger, I could vary everything but all I can change on this load, and then only marginally, is the charge so I'm happy with that. Just have to see what it does in the field when I can. Yep, we live and learn, your last post, Kent, is what I also find. I see that you too have learned. A year ago in relation to a low SD in the Hornet you said, "the Hornet is actually very good at this but needs attention to fill levels and primer balance. What I don't understand is why as you increase the charge there's very little change in velocity but everything smooths out nicely. Having said that, now it's sorted, who cares?

Not sure were your coming from I still feel the same as that's what I have found, still messing, still experimenting best Std Deviation so far is 18.4 then 21.6 but have had some up to 80's . the two best are with xx and xx.2 grn Lil gun and CCI small pistol RWS brass and 45 grn bullets from sierra. The worst SD was achieved with Remington S/rifle with 10.8 grns of the same powder one shot got up to 2933 the low was 2722- that's real bad and scary unpredictable! I have another with the same primers I have just written a rude word in my SD notes and not even recorded it I plan to work on some 40grn bullets this summer (I do load development in hot weather) I suspect it will come down to single figures when I get everything balanced, its still shooting silly small groups twice as far out as I first expected it might though Quote Link to comment Share on other sites More sharing options...
