I had taken the time to reinforce the hogue and felt this to be a worthwhile effort until todays range trip.
I am satisfied with todays testing and feel more confident knowing the rifle will shoot I just need to locate another take off HS Precision or BC Medalist stock. It is my finding that errors in shooters form, handloading regiment, and poor equipment will magnify with subsonic loads. 300 Whisper and results have been good with both platforms. Today I changed the hogue stock with my HS that was on my 5R and tried again with the same factory Corbon and group shot a solid 3/4" 100. Yesterday I shot a 100 yard group with factory Corbon subs with 220 SMKs and shot a 2" group. I have used diffirent powder and combos of bullets. I have been extremely aggravated with the performance of sub loads in my ACC-SD 300 blackout. Any suggestions for heavier bullet sub loads? Thanks for any help Using the same brass, Forster dies, and I have several pounds of different powders to try. New barrel 1-8 22 inch long no taper 90* crown Old barrel 1-10 16 inch long no taper 11* crown It's about making a rifle do what I want it to. This is not about what I will use it for or why I want to get groups smaller. Things I have tried are giving me around 1 inch groups the best being just a bit under. My issue is now I put a new barrel on with a faster twist to go subsonic and I am looking for advise on reaching a comparable level of accuracy with subsonic loads using heavy bullets 175-240 grains. 3-.4 with standard off the shelf bullets. 35 for five shots when using high end bullets and. I have had decent luck with supersonic loads averaging between.
#ARE SUBSONIC ROUNDS MORE ACCURATE FULL#
To find out more about ELEY’s subsonic and supersonic rounds, head over to our ammunition page to see our full range.I have been working very hard with 300 blackout savage bolt gun over the last year to wring all the accuracy I can out of* this little cartridge. When combined with increased velocity, flatter trajectory, and greater energy at the target, this allows hunters to humanely dispatch targets at greater range compared to a subsonic round. ELEY’s supersonic high velocity hollow round features a hollow-nosed profile and low antimony levels for maximum expansion and stopping power. This is because you’re not only relying on accuracy, but also stopping power and expansion characteristics too. Hunting, on the other hand, is slightly different. This is particularly important when shooting timed events such as Rapid Fire Pistol and practical shooting disciplines. Although the difference in accuracy may only be miniscule, for those competing at the highest level on the ISSF and Olympic circuit for instance, the smallest change can mean the difference between qualifying for a World Cup final and even if they take home the gold or silver medal.ĭue to their lower velocity, subsonic rounds also generate reduced recoil allowing shooters to get back on target faster. Let’s put this into context for different shooting disciplines. Nevertheless, the perception of accuracy is dependent upon application. This makes them more accurate at shorter distances because they aren’t affected by the inherent instability resulting from supersonic rounds returning to subsonic velocity. Subsonic rounds on the other hand don’t suffer from this problem.
As the bullet loses velocity, the transition from supersonic to subsonic can destabilise the projectile reducing the accuracy of its trajectory.
#ARE SUBSONIC ROUNDS MORE ACCURATE CRACK#
This produces the small sonic crack you hear after the round is fired. Put simply, supersonic bullets break the sound barrier. Supersonic: over 1,100 feet per second So is there a difference between the accuracy of subsonic and supersonic rounds? 22LR, and rounds can typically be split into two velocity bands. Many target rifles and pistols are available chambered for. 22LR round is one of the most common cartridges used worldwide. Here, we’re looking specifically at projectile velocities for. Understanding each element and its potential impact allows you to introduce measures to help limit these factors. Barrel maintenance, air temperature, wind speed, ammunition type and even the shooter themselves. We all know that there are a multitude of factors that can have an influence over shooting accuracy.
