jorge,
Some rifles will put various weight bullets in the same group, especially in certain chamberings. My pre-'64 Model 70 .300 H&H do not, and neither did either of my other .300 H&H's, one a custom rifle on the post-'64 Model 70 "classic" action, and a Ruger No. 1B.
To ask a rifle to do this, is asking a lot considering how many different bullet weights there are in the 30 caliber you have to choose from. However, to get a rifle to shoot the 180's and 200's into the same poi, that can be done. I was at the range last month testing one of my new rifles and this is how it did with both 178 grain match bullets and the 200 grain partition:
These ^^^^^^^^^are different charge wts too, as I was looking for a good load for this rifle. It is not finicky at all...
Here's where it put the load my other m1917 likes:
Oddly enough, that's exactly where my m1917 puts them too. Who wouldu thunk that??
So what do you do, when 2 rifles shoot to the same poi? Ha ha...
Don't make me dig up a target pic from my pre 64 fwt 30-06 and this load... That could be 3 rifles shooting to the same poi... Just the way I like them..
Oh, by the way, I tried some old Norma 130 gr. factory loads that I picked up at a LGS for $10.00/box and we don't even want to go there on where they hit the target..
. Lets just say, not the same POI... You probably already guessed that though..
