Carcano 7.35 load results!
While looking in the storage cabinet for something else to test I saw my bottle of 10 X.
It's an OK powder for the .223 taking just a bit more to equal my IMR 4198 loads.
So I thought it might be interesting to try in the 7.35 Carcano with 128 grain jacketed soft points.
My previous tests with this caliber were less than satisfactory. Using Lyman data and IMR 3031 powder I was getting hand size groups at 25 yards.
I never made it to the max loads as there were signs that I could not proceed past the starting load of 34 grains.
Just to have some loads on hand I just settled for 32 grains as an ok to shoot load.
Since there is no data for 10 X in the 7.35 data for the 30-30 with 130 grain soft points was my source
Using the 10 X powder I started at 25 grains and increased the charge one grain at a time up to 30 grains.
The 25,26,27 and 28 grain loads produced groups in the 1 3/4" range much the same as loads using IMR 3031.
At 29 grains a three shot group was just slightly over an inch a definite improvement.
When the 30 grain load was tested the group dropped to 3/4" and may be as little as 3/8".
While testing I shot an additional round loaded with 3031 by mistake which entered the same group. I believe it is the hole at the bottom but I ran out of loads and could not re-test the results.
I was supposed to fire that round at the other target.
The rifle was shot sitting resting on a gun case. This is probably the best open sight group I have ever shot with a bolt action center fire.
Now if 10 X powder can make this big of a group difference with the 7.35 I will also try IMR 4198 as it is similar in burn rate as 10 X.
For those of you who shoot the 7.35 this may be of interest. I have never had this large of improvement with a powder change in a centerfire rifle.
Targets posted show a typical 3031 group and the other target shows the 29 grain load as low and the 30 grain load above that one.
