1-10 twist and 155 gr Palma

[kansas]

I see another thread about the Palma and didn't want to HJ his thread so is anyone out there shooting 155 gr Palma in a 1-10 twist with any luck? I've got a Criterion 24" bull barrel and am, after quite a bit of work, finding a decent load for the 175gr SMK but the best I'm getting is .5" groups. I've worked with the 178 gr Amax with similar results, actually a little larger, and like the BC of the 175 SMK but would like a little tighter group. I always thought a faster twist liked heavier bullets but I've talked to a few shooters that like the Palma but I don't know what twist they are shooting.
I'm shooting some local competition that shoots between 300-1400 yards and am afraid also of keeping the lighter bullet stable past 1000. Any experience with this? Thanks.

Try the 155 scenar bullet. It might shoot well out of the 1/10 you have. it is also longer than the sierra palma bullet. almost as long as a 190 sierra.

My 26" 1:10 Savage 10FP LE2b shoots the 155 Scenars and 2155 SMK 155gr Palmas pretty well.

Get them up to 2900-2950 fps and you should have a chance.

My Savage M10 shoots the SMK Palma (2156) the Nosler 155 CC the Berger Fullbore 155.5 Equally as well. It has a 1-10 Twist rate i have taken these rounds out to 1220 yards with no issues as of yet.

Thanks for the info. I hate to spend another $30-50 on a box of bullets only to find they won't shoot and it's something that I should have figured out before buying.

My gun shot the 2155 Palma SMKs very well, then I switched to the 155 Scenars and I have not run through my stash of 2K scenars to be able to try the 155 Bergers or the 2156 Palma SMKs.

ETA: My gun has an excellent shooting node down at 43.6gr Varget and another excellent shooting node up at 47.8 gr Varget in Win cases with CCI primers.

I just got a 1/10 twist 308 and have been wondering how they would work with my 20" bbl. If I can get to it soon enough I will test them out.

I know this is an old thread, any update on the Sierra Palma in a 10" twist 308?

I keep thinking about some berger 155 or the sierra 155 palma. I want to go shoot a 500 yard F class and I think the lighter bullets can shrink the groups down some.
