200 yard groups . Need help

New guy Here, I found a nice load for my custom rem 700 270 win. It groups nicely at 100 yards and 1 inch high. Wife and I went to range and tested it out at 200 yards. .. Heres the question. At 200 yards it grouped it shots at 1 1/4 to 2 1/4 high . Wonder is it poor centering by us or poor load for rifle.?

The load is 61.0 gr of H4831sc, Fed. 210m primer. 130 gr hornady sst.
vel. 3226 fps out of 25 inch Bench mark custom barrel.

This load is 1 gr under max form Hornady book.

We are new to this and looking for help. And yes my wife out shot me at 200 yards !!

Re: 200 yard groups . Need help

To me it looks like shooter to scope alignment issues. Consistently shooting high and right but with occasional pulled shots and grouped vertical stringing.

IMHO, I think the shooter is not getting the same sight picture each time and it could be both of you have issues with the scope set up. I have an buddy with a fair amount of experience who is not consistent behind his scope. At 200 he can shoot MOA, but with his rifle I can shoot .25 moa. I don't like how is scope is set up but I also know how critical it is get in behind it because it is very particular.

Part of the reason I say these things to you is that I don't see the weird flyers associated with inconsistent pressures/loads. At 200 yards the cross hair movement is quite a bit more noticable on paper.

Thank you, Brent. This makes great sense. Mary was shooting my rifle and the lenght of pull is to long for her. [ her rifles in the shop ] I didnt feel real comfortable at shooting table myself. I will reload some more rounds and see if I cant get more comfortable and consentrate on my alignment. Thank you very much Sir.

I don't know if you put only one 3 shots group at 100 yds but comparing one 3 shots group to two 6 shoots groups is statistically a bit unfair for the least. You know what I mean?

One 3 shots group might be better than your average. On the other side if you pick 3 shots out of your 200 yds groups you can easily ended with a group under an inch.

How fast where you firing? With small diameter factory barrels the heat from firing to fast will make your groups larger. Also in the future, it would help to do your load work up at 200m and not 100, this will allow your bullet more time to stabalize.

He wrote that it is a 25" Benchmark barrel, but didn't mention contour. Good points otherwise.
