Cabelas has the blue box in the fall catalog at a pretty good price. Which would be most suitable for a 1/9 twist. The 68 is much cheaper than the 69.

Thanks

It is all going to depend on your individual barrel.  I did some accuracy testing with my 16" 1 in 9 Crome lined barrel this weekend.

69 grn SMK   avg 1.75" @100 yrds
68 grn MHP   avg 2.875 @100 yrds
60 grn VMax  avg 1.25" @100 yrds
52 grn MHP   avg 2.375" @100 yrds
50 grn VMax  avg 1.375 @100 yrds
Q3131a       avg 2.000" @100yrds

All ammo was Black Hills blue box (except for Q3131a)

Your Milage will vary.

Looks like yours didn't like the 68 as much did it. Thanks for the quick response.

My 20" Stainless Steel Bull barreled varmint rig likes the 68gr Heavy Match HP to the tune of 1/4 MOA out to 300 meters.

I've shot a few literal one hole groups at 100 yards with it.

I picked up a case of it from the June Georgia Precision sale for right around $15/50 rounds.

Try both and see which one yours prefers. A 1:9 barrel won't care between 68 and 69gr, stability-wise. It's funny that the 68gr bullet is actually longer than the 69gr! (different ogive shape).

I have a DPMS 16" SS bull barrel 1:9 and it likes the 69 grain better.  I get about MOA at 100 with 69 grain, but get 1.5 to 2 MOA with the 68 grain.

Try both, and see what your rifle prefers.
