dead on....
 

I went and shot at 100 yds yesterday and had an interesting 4 shot group... 4 in high dead on left and right, 2 in high dead on, 3 in high dead on, 1 in high dead on in that order. No movement left or right just up and down. Im questioning now whether the 777 pellets im using are rubbing off some of their powder while in the box. Seems like the powder load is not consistent. Has anyone experienced this before? I am cleaning the bore between shots with no. 13 and then 3 dry patches. Any advice would be helpful! thanks

How many pellets are you shooting at each time, and what bullet? That sounds like something in there is causing something. Have you ever considered loose powder. Also what rifle, and primer are we talking here?

RE: dead on....
 

well i have a prohunter shooting 150 gr. 777 and 250 shockwave. last time i was out the first two shots were in the same hole and the next 3 were w/in 2 inches. the only thing that was different this timewas that it was about 32-35 degrees versus 50 if that makes any difference. I feel like i need the 150 gr. load because i am heading up north where a 200 yard shot is a very good possibility. Should i try to see if it will group better with 100 gr?

you could try 100 grains but I would just work with what you have. Try a different swabbing solution, maybe that will help. Try some windex and alcohol mix. Try some different primers, try all sorts of things and see if that makes a difference. I am sure the rifle will come around. Good luck.

Maybe it's the shooter...?

Sounds like Breathing causing the up-down action.

Whats your bench rest set-up??

RE: dead on....
 

Be sure to try to seat the bullet(pressure the same every time,this will really help in group size. My Prohunter likes to have the bullet just seated firmly on the powder. If I use allot of pressure seating the bullet on the powder,it starts stringing the shots.

RE: dead on....
 

I doubt it is the shooter, but that makes sense about the breathing and going up and down...im pretty used to shooting rifles and have never had this problem before. The only thing that might be causing a little bit of variation is the slightly heavy trigger pull combined with the magnum load. But then again i shot my remington 1100 slug gun and the trigger pull is super heavy and i can still get about a4 in group with it at 100 yds.
should i run one saturated patch of no. 13 then dry it with 3 patches or should i clean it with several wet patches and several dry ones trying to get it as clean as possible while shooting on the range?

It's just the opposite! Bullet is not consistent with the powder load. This minor vertical stringing is the bullet holes-way of asking you for either 90 grainsin pellets (most likely)or 110grains (not likely).That means you need to start carrying some 30-grain pellets - ortry the 50 gr.Pyrodex pellets -- or switch to 777 loose powder.

Inconsistency with 777 pelletsis nothing new. I read about it all the time. But yours is minor and probably correctible. This is why I stick to 777 loose powder. With loose, you can tweak your powder chargeusing single digit numbers.

RE: dead on....
 

Agreed, that is one of the things I pay the most attention to is seating pressure.

The weather change can have an effect though you should see through out your group vs a stringing effect. Ie: now your shooting 2" low vs dead on!

It very well could have been an off day as well or bad rest so before you worry about switching, test some more and pay attention to detail.

RE: dead on....
 

if i pick up a box of pyrodex pellets and keep the 150 gr. load, how will this shoot compared to the 150 gr. 777? ....higher, lower, or similar? I have heard about these inconsistencies with 777. do i need to be careful shooting 777 one shot, then using pyrodex the next shot as long as i clean it?
