Would this indicate bedding issues, the RED line is the lowest powder charge , then green then BLUE being the warmer one 3gr higher.

its my Ruger hawkeye 35 Whelen with 200gr TSX an 53-54-55gr varget...... is it some interest the faster it goes the larger the group gets, my Question is to get by for a bush hunting rifle where 200m is LONG, 100m is the norm, Large Deer, is it worth trying LOWER charges of powder to just see if it closes up a tad???
im not after MOA, i believe this rifle in this stock has always been a strayer, when i switched stocks to Ramline, it was shooting an inch to 1.5 all day w 250s... i noted a hairline crack in the ruger an did a bit of a fix up.. perhaps thats not worked- The short term fix of tryin them a few Gr slower may suffice for its needs now and then... but what do you think about this?

cheers

I have tuned up hundreds of target rifles for accuracy.

The absolute first thing we do is bed the rifle in a quality bedding compound. The two best (and easiest to work with) are Devcon F putty, aluminum or steel. The putty is not runny and does not shrink as it hardens (as most epoxies do.)

You have a nice rifle and I don't suggest you bed it yourself if you have not done it before. There is tricks of the trade, like using Plactercine to make blocks and dams to control where it does and a good mold release. I use duct tape on the front bottom and sides of the recoil lug. After the job is done, a lightly file the sharp edges of the recoil lug so it does not shave material when installed.

If you want to do it yourself, start with bedding your Cooey 22 and other cheap candidates, to get some practice.

I remove a 1/10" of wood, to make room for lots of epoxy. I leave a couple key spots of original wood so the action is correctly located in the stock.

I only explore accuracy after a rifle is bedded. Without bedding, accuracy and point of impact can change. Not acceptable in a hunting rifle.
 
Hey update!

I pulled the rifle apart, re tightened the action screws snug, loc tite and then................. and Then i wrapped like 5 or so wrap arounds of Duct tape just up on the end of the muzzle about 1 cm back............

then loaded lower down as mentioned the groups were getting faster and further apart........... 52GR Varget------- results.

MOD

i mighta let one off a little to the side, but the other two were half an inch apart... never had horizontal issues apart from my shooting- fairly pleased the vertical has gone somewhat...

i ended up loadoing the remainder of the TSX with the 52gr and it is Zero right on 100m Bang on........ deer meat for dinner.

What happened, ?

I know i played with the Barrels harmonics... thats about all i know.
 
If the Hawkeye has the same bedding arrgt as the Mk II, it can be problematic. Most mauser style actions have some bedding support immediately in front of the recoil lug. The Ruger does not, instead it relies upon a pressure point at the forend tip. This makes the gun sensitive to a warped forend. This appears to be your case as the groups improved when you switched to the Ramline. If you want to use the wood stock you need to get the action glass-bedded by someone with experience. Its not particularly expensive - about the same as a night at the pub with a Sheila.
