Home from the range

I just got home from a great morning at the range. I have been the process of getting some loads worked up for my browning 7mm and my rem 700 .243. The other night worked up 3 different loads for each gun.

In the 7mm i'm working with the 140 grain barnes ttsx.
Topped with a vortex viper 6-20x50 30mm tube
My first 3 tries went like this

61 grains of H4831
1 shot- 2800,
2-2848
3-2837
No signs of pressure
3 shot 1" group

63 grains of H4831
1-2961
2-2970
3-2966
No signs of pressure
3 shot 1/2" group

65 grains H4831
1- 3079- high pressure signs
2- no shot
3- no shot

Conclusion
the 63 grains of h4831 very accurate but I would prefer some more velocity.
So i'm going to try a few other powders in hope to find some more velocity and accuracy.


.243
Remington 700
topped with a vortex crossfire
95 gr berger VLD
I tried 2 different loads

37 grains of h4895
1- 3029
2- 3027
3- 3030
no sign of pressure
2 shots basicly same hole 1 shot 1/4' left

37 grains varget
1- 2950
2-2961
3-2940
no signs of pressure 3/4-1" group

Hoping to get a little more velocity and i'm in no hurry for the rifle to be ready to go so I will keep playing some more.


I also shot some factory loads out of my rem 700 22-250
hornady 55 grain vmax loads.
1-3678
2-3682
3-3658
4-3675
5-3669

Right close to a 1" group at a 100yards

Just thought I would share.

Re: Home from the range

The first group with the 243 sounds great. Are you sure you did not pull the shot that was a little left that way? Either way it is a great load with very little deviation in velocity.

The 7mm looks to have shot the 2nd group very well, with little deviation. I would not give up on it, but remember it in case you cannot find something faster.

My 7 RM groups well at low velocity, 2870fps. I have decided to live with it, and it is shooting well out to 1000 yards. I decided that accuracy, and low deviation, are more important than speed. Good luck with your development. Keep us posted!

I may have pulled the other shot on that load in the .243. I'm going to load a few more of that same set up and shot it again and compare it to a couple loads I wanted to try of the h414.

In the 7rm I forsure have that load saved as I completely agree with you. I will take the accuracy and speed of that load over more velocity and less accuracy.

Thanks for chiming in.
Justin

Re: Home from the range

if that 7mm is a 7mm rem mag, and if I was you, I would change powder or something. that's pretty much 7mm-08 speeds. a magnum should go a lot faster, easily. and still keep accuracy and a low ES.

Depends on the rifle. It can go faster, definitely, but some rifles are more accurate at slower loads.

It is a 7mm Remington mag. I will be switching powders and trying some more loads in it.

Re: Home from the range

I use h1000 with an es of under 20, I forget the exact number now, doing 3100 with a one hole group at 100 and an inch at 300 (162 amax) I could drive them harder but like you, id rather settle there with good accuracy and es.
