Need help deciphering the data

[terrydull]

You folks have been a great help to me. I'd like to ask for more opinions, if you don't mind.

I want to shoot a prb for accuracy and this the the data I have for the two rifles,

#1 - 54 cal, 33" barrel, 1:48, 7 lands, 7 groves, 0.006 deep, single trigger, 9.5 lbs

#2 - 54 cal, 32" barrel, 1:60, 5 lands, 5 groves, 0.01 deep, double trigger, 9 lbs

Just based on the data, can you suggest the one that would be more accurate? My head is kinda swimming with all the numbers.

Thanks!

Id go # 2 (and know yer done with any conicals for the most part)

Go with what Azmntman said. Slower twist is better for roundballs. You can even go slower than 1-60 and still shoot good but when you get into real, real slow twists, it takes more powder to stabilize better.

I like the slower twist and deeper rifling.

I think the 7 lands and grooves need some thought too. If the lands are slightly narrower than the grooves, there is opportunity for accuracy with a modest charge using a tight patch and ball combo. Use a spit or slightly damp oiled patch.

You will only know which rifle is most accurate by going to the targets and developing an accurate load.
