thanks for the loading info , I was hoping
to get an information on those who have used
162's thru a 9.5 twist, and how well they worked.
my loads will be with varget ( I have a bunch )
I have to make an order for some parts and am
thinking to throwing a few hundred for load
development but if they won't work I'll have to
step back and regroup
again thanks ....

I don't know why Hornady first came out with the 162 HPBT and stated it needed a 1-8" twist. Then still kept that requirement on the A-maxes. A 1-10" will stabilize them from relatively low speeds. I do this in my 7x57.
For my 7mm-08 I use either R-19 or R-22 46 gr. of R-19 and 49 gr. of R-22. The latter load is slightly compressed. If these bullets aren't keyholing, then they are stabilizing. If they just aren't accurate, you need to find a different harmonic (load) for your barrel.
A couple things to note here. You are keeping the factory 'varmint' barrel? Which to me implies you bought a Remington SPS varmint in 7mm-08? If so, you might reconsider that. As cutting down Remmy barrels has often proved unfruitful. Even their 'varmint' barrels are hammer forged and cutting them down releases/relieves stress in ways that can't be accounted for. In short, your barrel harmonics go haywire.
Regarding your group, 4" @ 500 to 700 is pretty damn tight in most cases. You might find it difficult to get that with a cut down Remmy barrel. A new cut barrel would be much more capable of providing that kind of accuracy. If you mean 4" @ 100 and want to shoot 500-700 yds., you might well again be disappointed with the accuracy. Could you clarify? </div></div>
thank you for the excellent response
I'm picking up a rem 700 7mm-08 varmint new
in the box next week, I'm having work done on the
action and replacing the stock, I don't have the
funds at this time to replace the barrel,
so the factory barrel for now, I hope when I
have it cut it works for now.. we'll see ..
as for range I'm looking to get 4" or so @ 500
not 100 . with that being said again we'll have
to see how it works out. I have tons of varget
and I guess I'll try my luck with the 162's
I was concerned it wouldn't stabilize with a
9.5 twist ... I just have to see on the harmonics.
thanks ... </div></div>
If the 162's won't work in your barrel, test another 'known' bullet. Try a Nosler 140 or 160 BT. Just to see if the barrel harmonics went nuts or it's just your barrel won't stabilize 162's. While a number of Remmy barrels HAVEN'T worked out for people a number of them HAVE. So, if it works for you, good deal. Just don't give up on it one or two bullets into trying. If it still doesn't work out, you'll have the rest of those bullets to shoot in a barrel that does.
