On average, the heavier the bullet the higher the bc and the harder the kickback. Boattail helps, but, still for the distance shot, where to draw the line between best bc and lowest kick? Assuming .308 your thoughts? .................................................. I put a muzzle break on the 300 win-max, (which dropped the kickback to near the .308 but the noise increased)) but am using the .308 now and the deer still drop and I do not use the increased range
as a child, i would discuss these type of subjects with my late father. i know very very little because i dont shoot but i have shot a bit but not for sport(not at competition level) i never stepped into the load your own class or got into comparing long distance stopping/killing dynamics im guessing you wont be changing your barrel to something different ? & you wont be changing your powder ? & you load your own ? so im guessing your not going to tweak your burn rate of muzzle compression of your barrel so your just changing the over all charge(?) & grain & projectile type ... that's outside my knowledge base i assume cross winds would make a huge difference to boattail ? assuming you don't need increased penetration at that speed & weight a brick would be sharp enough to stop the deer & any limb or bone it hits will deliver a lethal catastrophic injury & death inside a minute to 5 minutes outside chance you want through n through for better butchering ? boattail will give you longer flight in cross winds dropping your grain may help a tiny bit for distance & arch but there is only soo much physics can be tweaked i was picturing those muzzle fitted side exhaust discharge ports pointing slightly backwards maybe that would shave a tiny fraction off ? might add bounce but after its left the barrel ?
yes greatly reduced kickback but lots more noise directed back at the shooter Please Register or Log in to view the hidden image! must use earplugs
243 and 308 Winchester are excellent all-purpose rounds based on the same cartridge, which is compatible with the 7.62 NATO (with careful selection). A 308 Winchester rifle (designed for high power loads) can handle 7.62, but the reverse is not recommended The 243 is just a necked down 308. That's what I call utility, for self-loaders.
A few years ago, I was chatting with the local gunsmith(Pat) after getting ammo for the 300. He told me that after a few years, I would develop a problem from the kickback of the 300, maybe including flinching as I took the shot. It took a few years but: Pat was right, So, I bought a better pad and had him install the muzzle break. While he had the rifle, I bought the 308, and for a couple years switched back and forth between the 2 before settling on only using the 308. as re: (2nd/3rd round) ? No. I only load and fire one round--and that only after I see the target. (If you can't hit what you're aiming at---STOP SHOOTING!) The cataracts are getting worse----will get the new plastic lenses within 2 months, then will see if my vision will improve to where I feel more confident...? Also, I ain't as steady as I was 45 years ago(when I never missed at 400 meters with iron sites), and can only hold about 1 moa on most days, so don't take the long shots very often. (the vicissitudes of age)
so you do not want to retard your nervous response or speed it up i assume but you have haptic feedback habituated nervous reaction(flinching) im musing here so think broadly not specifically nerve speed nerve speed slows down flinching starts as a delayed reaction to the recoil so the flinch is 2 things 1 the delayed push back to the recoil the body telling the nervous system to defend nerve issues like using power tools for a while & your nerves keep vibrating experiments i would suggest stripping all metals from your diet & all calcium for maybe 3 to 5 days then see if your flinching is reduced on day 5 & 6 etc just for a test not for a new diet brain speed will remain the same i guess but everything else will probably be trying to run the same program at different speeds additionally masked pain masked pain from a high pain threshold & joint & bone pain can illicit subconscious reaction to defend you may not be registering the pain in your conscious only your subconscious but it needs fixing or adjusting. experiments have you tried having a couple of really strong coffees before you shoot to test some safe nerve accelerants ? coffee also accelerates the body slightly to more practical steps spreading the load so you double your stock to shoulder ratio the more advanced foams can have timed compression ratios if you have a friend in nasa you can probably get them to get you a cut off scrap of a couple of different speeds experiments you may also try some shiatsu prior to shooting where you use a padded club(or the palm of your hand) to gently beat your shoulder to get the tendons & muscles to tighten up pre shoot see how that goes NOT massage ! you want compression to cause tension so everything gets in its reactive position at specified nerve speed & muscle tension(i use this in my physical training, an advanced form of shiatsu)
