Re: Anybody have any ideas?
I had one group measuring 0.24 and another measuring 0.38. Other groups were from 0.75 to 1.00. Later in the afternoon i duplicated the same two loads that shot well and could not get a group under an inch.
You have gotten some very good advise from some good folks here.
Let me see if I can add a little.
I am familiar with a Rem.700 but not your particular Mdl. I am thinking it is a factory un-tricked rifle. If so groups in the 2's and very low 3's are indeed hard to come by on regular basis. It's like a bowler who bowls 300 once in his life and spends the rest of it trying to do it again. Not impossible but difficult.
I shoot a Mdl 70 Win. in 270 Win. People who bench rest won't even talk to me when they here I shoot a 270--But-- using a Buds bull bags and my Zeiss
3-10 Mill dot scope I can do 1/2'' all day long with Nosler 130 Gr. B/T. and 51.5 of IMR 4831. All loads from a RCBS charge-master and checked on a beam scale, .025 off the lands. I have shot in the Mid. 2's with this load but it's every 3rd or 5th time. I can't seem to do it every time.
I shoot at 3/4 inch dots at 100 yards and with the 10 power they still look small, but I can still split the pie. Ok my point is for me to shoot below the 1/2'' and get to the mid 2's everything MUST be the same. I have a tight chamber for a factory rifle, My rounds are .305 at the neck loaded and the necks are .308 after fireing. That's about .003 clearance. I turn my brass to clean up the necks, about 70%. I use a bushing die and only size 3/4 of the neck. This leaves about 1/4 of the neck as it came from the chamber. I use all rounds with over .002 run-out for Fowler's. I anneal the brass every 3rd time.
Primer pockets/flash holes/ trim to length chamfer and debur are all addressed. That being said the rest for me is on the line. If the wind is not looked at, or my trigger work is not exactly the same/ or my position on the bag
or anything changes --well so do my groups. I shoot at least 4 shots for a group. I load five of each for load work up.
Your best shots could be just by chance or it could be you. How about barrel temp. or the kind of day, temp. Humidity, ammo temp. I keep my ammo in a cooler when it is hot out--I take out 5 rounds at a time. Staying in the 2's with a factory rifle is very hard for me.
I can do it BUT Like I said everything must be the same.
I think that is a good reason the bench rest boy's don't just spend $3,000
for a rifle and think it ends there. They load for the day and the weather,
They load at the range, read the wind and on and on.
All of that and the expensive rifle to shoot on average perhaps 1/8" groups.
That's a 1/8 smaller than I can shoot with my 270 Win. BUT they do it almost every time. Consistence is the name of there game.
Sorry for the long winded post. Hang in and shoot some 10 shot groups.
Let me add my trigger is 3.5 pounds and I think that is not helping.
No I know it's not helping.
