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.
if i have critters around my house i need to use Sub. Now civilian use i may differ from Dust on this. yes as both Dust_Remover and i have said tactical would be SHORT range as in urban (100yrds +or - a bit) Thank you lonewolf for the factual info, do you have any numbers to let us play with?Īs for the use of the sub round. Okay, this thread seems to be getting a little off track here. From the civilian standpoint, it's the desire to shoot the critters that are causing problems in the yard and you don't want your neighbors to be the wiser. I would run the numbers to figure out the differences, however I just got off work and i'm tired, so i'll leave the math to someone else.Īs for sub rounds from the tactical point, if I were in a combat or police situation where I were using sub rounds with a supressed rifle, I would likely be using them in urban conditions where the ranges are low, and the need to keep your position concealed is crucial. Yes, it's losing rotational speed, just not as quick. The rotation of the bullet still encounters friction from the air, however at a much lower coefficient of friction. The bullet actually is pushing against the air, and the friction of the air on the sides of the bullet is causing it to lose velocity. , and plinking past 150 isnt really in the nature of this round either so now accuracy is the only thing we need to worry about for plinking at say the 150 mark which is where we start loosing life on the roundįor the chart i choose a RN as the weight is pretty evenly distributed through the bullet and would NOT need to be loaded backwards (i still think it is more myth than fact at this time as the RN would disprove the backward theory)ĮDIT: after looking at the chart, i think this round may hold better than i thought even possibly out to 300 with out toumbling? anyone agree?Ĭlick to expand.Not quite, the bullet is going to lose some rotational velocity, however it won't lose it anywhere close to the rate that the velocity of the bullet itself is losing. the bullet will not start tumbling before 100rds in either load, so lets face it the only real use for sub is plinking, and a sub round should hold at least a 2" group at a 100yrds bare min i know ther is debate on this and i think that i need to load up a batch to see for my self.īut in the mean time lets look at the chartsįor tactical uses, anything over 100yrds wouldnt be done with Sub. The backwards load isnt solving the issue of accuracy. Yeah i read that as well, but the H*** if i am going to be the one that tries to figure out that pressure on my rifle with a load like that ? i mean if you load up backwards then think how FAR off the lans it will be.
