55g vs 62g in a 1/7

[35percent]

The 62 grain may shoot worse, the inherent accuracy of th etwo piece core makes it a generally less accurate round.

Don't believe the bullshit about a 1/7 not shooting 55gr accurately. Molon dispelled that myth.

This, and different guns will be more or less accurate depending on the load, but it won't be a huge difference at 100 yards.

So we just covered shooting 55s out to 100 or 200 and it seems that it's fine.

Is it also no big deal to shoot these out to 500 like for gongs and the like?

Give it a try. It might surprise you. I have had great accuracy with the Hornady V-max rounds through my 18.5" 1/8 barrel, and my 20" 1/7 twist HBAR.

I do buy and love 62gr. for blasting ammo, training, and stock pile when I can get 'em.

The most accurate round I've loaded to date was topped with a 55gr Z-max. I've also had excellent results with those bulk 62 grainers from Wideners and TAC.

On a similar note, I have shot 40 gr bullets through a 1/8 twist that was otherwise intended for 60-75 gr stuff. Despite the optimal twist being somewhere in the 1/12 range, the 40 gr Vmax's shot just as well as the 50-75 gr bullets of similar quality (Hornady Amax and BTHP) out my 1/8. When I say shooting well, I mean 5 shot groups however around the MOA range.

62 gr have generally always shot like crap no matter what load. Even the cheapo 55 gr SP's I had considerably outperformed them.

Don't get sucked into dogma needlessly. Having too fast a twist only becomes a real issue if bullets are going very high velocity and getting spun WAY too fast, like a really light bullet in 220 swift.

FWIW, shooting 5.56 62gr FMJ, and Indy M193 at 100 yards was the same with my shooting. .223 FMJ 55gr had a too different POI.
So I would have changed my zero slightly.

Out to 600yards, minute of steel man, is where I saw the difference. I should add that it was solely because of pressure. .223 55gr requires a greater holdover. When I get home from WI, I will test the three FMJ loads I have.

With my COG zeroed at 100 yards with CBC 62gr, 5.56 77gr shot about an inch or two low and to the right. I thought it would shoot higher. But it shined at 600. Again I was not going for groups, but it seemed this bullet, even without optic zeroed for it, flew the straightest.


*The "testing" I did has no value outside the life of Zane, just thought I'd share my expirence with bullet weights and how they act in my good with my own shooting.*
