![]() ![]() 22lr, you're given a 40 grain bullet and almost universally, a 1/16 twist - it works OK'ish and has done for over a hundred years. Over that same 50 years, centrefire accuracy has improved in leaps and bounds - 20 years ago a sub 1 moa rifle was something talked about in hushed tones, now it's pretty run of the mill. 50 years later, nothing much has changed - the targets at 100 yards are still the same, rifles are better but 100's are still fairly rare. In the 1960's I was shooting NSRA prone competitions with a BSA International and Tenex ammunition, on the 100 yard targets, scores in the mid to high 90's were quite usual but 100's were quite rare. 22lr has been around for 150 years, the Captain of the Cutty Sark and Abraham Lincoln would both have been quite familiar with it, it's scarcely changed at all. A silent lead HP 69grain bullet at 1050 and 170ftlbs with sub 1moa accuracy at 100 yards sounds good to me, especially if you already have the rifle. Why can't we develop a load that performs better than the humble. 22lr sub is excellent at the job it's designed for, small game at 40-80 yards, and yes, I know it can be taken further but accuracy is, at best, fairly mediocre once you get round the 100yard mark. 22lr subsonic at 1050 gives 97ftlbs - a 69grain bullet at 1050 is not far off double at about 170ftlbs. Being able to just change mags to a full power. 22 and seen a fox just out of humane range. 22lr with subsonic ammunition is that it's so very quiet, and as such is idea for rabbit sized pests at moderate ranges in noise sensitive areas, however, on a good few occasions I've been out with the. It does make me slightly nervous as far as squibs, but given our known velocity at 3.1 is high, I think I’ll be ok.I can certainly see the sense in this, I'm just surprised it's not done more often and amazed that the accuracy problem doesn't seem to have been really cracked yet. No way I’m getting 60 fps more out of a barrel 10 inches shorter. This is why I can’t imagine the data from Hodgdon is out of a 24” barrel. We got supersonic loads from subsonic data, and I’m shooting a 14.5” barrel. Gun didn’t even begin to cycle as expected. I was shocked at how relatively good the SD was given the case fill. The speed of sound given my environmental factors is 1,106. Now, the interesting part: these clearly were not subsonic. Accuracy was surprisingly good at about an inch. ![]() I shot three at 25 yards without a suppressor to make sure they were flying straight and I wouldn’t get a baffle strike. The specific subsonic loads document does not list barrel length. They say it’s out of a 24” barrel, but I’m thinking that’s a generic number for the rifle data and is not accurate for this load. This is published load data on Hodgdon’s website. Quick info: 3.1 gr Titegroup under 55 gr FMJ 2.200” OAL.
