Home Forums Reloading Big Game Rifles Accuracy test

I did some accuracy work ups yesterday. This is using the Magpro in Model Seven SS 7 SAUM with 22" barrel. The speeds from top to bottom is 2780, 2800, and 2840. I was using a 160 grain Accubonds.

Looks like you might have a bedding issue. Getting 1-2 groupings. Shoot 5 shots and see if you get 3-2 groupings... You asking a question in regards to your accuracy or lack thereof or what???

Lawrence you don't think messing with the seating would help?? Then again the op didn't give much info on the gun I'm going to assume it bedded.

Good point. You may be on to something there.. However, I don't assume anything is bedded around this joint... OP still a little vague..

These are some of my first reloads. I probably haven't loaded 30 rounds yet. I still got alot to learn.

Is your rifle bedded?

If its 3 diffrent loads, I would take load 3 vary the seating depth 5 thou up and 5 thou down,then take it out to the 2 or 300 if possible and see how they do.
2 tight and one out for a hunting rifle isnt bad.

To me, it appears he is reloading by the Nosler book to saami spec in a factory rifle, so with out measuring to the lands and then measuring the loaded ammo to the ogive, by having him move the bullet in and out would not be advisable. A factory gun and factory duplicate ammo is most likely .120 or more off the lands to begin with.

If it is a box gun shooting per the book handloads , his group isnt that bad, could be better with a different powder, but it is still what one could expect from a box gun shooting basic handloads from a 22in barrel.

More information about the gun and the hand loads would help, but Id hesitate giving much advice with out more info.

Hunting rifle + hunting load = plenty accurate for big game hunting !

Sometimes you go with what info you have. More on the rifle and loads would help, but as BSA said earlier 3 shot groups really mean nothing. 5 shots are more helpful, but then again so is a little distance which is why I suggested the 2 or 3.

load development target for 110 accubond out of 25.06 at 200.



Target 1= 5 thou longer than Nosler book.
Target 2 = 5 thou under
Target 3 = Nosler book
Target 4 = 15 thou under
Target 5 = 25 thou under and 5 Thou longer than the proven 117 Sierra load.

As you move beyond 100 yards, shooter ability/influence/error increases. That is why at this point to shoot at 100 yards reduces shooter error and allows focus to be on gun/load.

If you read in the Berger book about seating depth test, they indicate seating depth nodes of .040 as a starting point then refining from there. We generally go with Bergers manual since they have pretty much been one of the key innovators of the "load long " movement.

Our above post on the Ruger Precision Rifle .243 shows our tests as well, just we kept it to 200 yards for reasons of development of ES/SD so we are good to go beyond 600 yards.

I see Larry the douche-bag is back..
