Need ammo suggestion for carbine 1:8 twist
Hey folks,
I am new to the forum but not new to shootings. Ordinarily, I strictly shoot .308s but I have bought a smith a wesson m&p carbine with then1:8 twist barrel.
I will be shooting both with and without a suppresor but hopefully will not need to change ammomduemto the can. I plan oshooting no further than 600 yards max.
Question : what is the best bullet weight to sight in and shoot with? The heavier the better is my philosophy so I'm thinking anywhere from 70-77 grains.
Next question, I will be shooting with a red dot sight co witnessed withnthenstandard a2 front sight. If I want to be able to shoot from 100 to 300 without having due massive dope adjustments what should I set my initial zero at? Unfortunately their are no 50 yard ranges around so I might have to use the outdated 100 yard zero. What do you guys suggest? Also, I will have back up sights so I plan on setting the front sight flush with the base of the sight....what should I set my rear sight at? 8/3 and then plus 2 or 3 for longer range shooting?
I've read the posts and charts by the master on this site with all the bullet poi/poa charts imjustbneed to know what will work best with my set up.
Thanks for the help bros.
Bullet weights out of a 1:8 carbine
Thanks for the info. I'm pretty well versed in shooting and ballistics but have never owned a carbine with the 1:8 twist rate. I'd like to go with the heaviest weight round I can get so I can shoot as far as I can. Keep in mind that will be shooting with a full,size thunderbeast 30p-1 can on the end which may or may not help accuracy out of the weapon.
Anyone on here that shoots the same type of set up I'd love to hear what works best for you. Sounds like anything from 60 grain all the way up to maybe a low 70gr round may work well. The 77 grain round may do ok at short range but at 500 yards it may be looking like wobbly thrown football.
I don't need sub mo accuracy but I do want to be able to shoot at least 1 moa at up to 250 yards and then maybe 2-2.5 moa at anything past that.
Really, I'm just using this rig to keep my m4 skills up to qualification standards
