I used the search and found some pretty helpful results but i was just curious if anyone had finally worked a load using 110gr Accubonds.

The Nosler website gives load combination with an indicate of the most accurate load.

When I had a .270, before it migrated to one of our sons, I tried to turn it into a varmint rig using 90g and 110g bullets from different manufacturers.

I got them to move out ok with H4831 but the accuracy never seemed to be acceptable. If the critter was close enough, say under 200 yards, it worked but was very damaging to anything it hit. Beyond 200 yards it was a hail mary.

I ended up sticking with the 130g. NBT and found that it elevated the accuracy up to a point where it extended the range way out there and also provided good practice for the big game seasons in the fall. Since I was spending a lot of time chasing varmints I ended up getting a 22-250 to do the varmint work and never looked back. Shooting that .270 45-55 times a day didn't seem to be the ticket.

I've come to the conclusion, that for me, a rifle/caliber seems to "work the best" when you find the appropriate bullet weight for the most used application and then shoot it a lot to gain familiarity with the performance at all distances.

Just to give a little update to my experience. I started this afternoon working a load with IMR 4350. I started at 56 grs and ran out of light this afternoon but ended up at 58 grs. I havnt ran one through the chrono yet but shot a 1" group with 4 shots at 100 yds with 58 grs in a Tikka m695 with a 22" barrel. I will continue with my loading tomorrow to see if I can dial them in a little tighter.

Jason, back when I only has a .270 Win, I shot prairie dogs with the 90gr Sierra HP's. Like Teancum, I didn't have very good luck with H4831 and the lighter bullets, but H4895 was a different story.

I was shooting a max load of H4895 in necked down Army brass. I was getting 3500fps, and sub moa groups. It would sure launch the p-dogs high into the air.

The 110gr AB was designed with the 6.8 SPC in mind, but it could still be fun in a .270 Win.

Taking a look at the quickload data I'd probably try:

RL17
W760/H414 (they are the same powder)
Hunter
4895 (which ever one I had on the shelf)
4350 (again which ever one I had on the shelf)
RL-15
H380.

I think any of those could have Potential. They are more or less in order of velocity potential, but I'd probably start with the two or three that I had, or shot the most.

I hope this helps. Let me know if there is something more I can do for you on this.
