my dilema

ok here is my issue. i have a remington sps .308. i had a load developed for it that shot inch groups at 100 pretty much every time. (after joining this site im less happy with my groups) this was before i did some tinkering on the gun.
i had already floated the barrel so that
after doing heaps of reading i took the stock drilled out the bolt pillars, put in aluminium pillars and beded the action. it now fits amazingly snug.
i then got a bipod and found that the stock was no wear stiff enough. so i epoxied in some arrow shafts and now it is way better.
so now i have a bedded and floated rifle . have been doing some shooting and it doesnot group very well now. in the 4 inch mark. thats with a sandbad and the bipod.
the load was developed in colder temp in winter. around 10 c on average. its alittle warmer now. about 16c. the load im using is 45.6gr of ar2208, remi cases, winchester primers and hornady 150 btsp.
would the tinkering i have done change the nodes and such.
im planning to change bullets to the 168sst for longer ranges. hoping to get is accurate enough for 500m shots on animals. kind of want to keep the 150 for under 200m shots since im not sure how the sst will be at closer ranges.

so do i just have to redo the load development for the 150 and i will have to do it for the sst too should i just shoot the sst?will they be ok at closer ranges. . sorry for the lond post. i will come up with more questions as i get replies though.. cheer everyone

Re: my dilema

foreign,

From my experience I would suggest that a redevelopment of the load would be appropriate.

As an example, I had a load worked up for a 7 Rem Mag and learned that that it needed a skim bed job. This one, some don't, required a rework of the load and readjustment of the zero.

Hey, ya gotta keep the industry supported.;)

Re: my dilema

What were the groups before the bi-pod?

I am still not convinced that the stock is rigid enough!
If your groups are not just about equal with or without the bipod then you need to correct that first.

I have a Savage with a Tupperware stock. I put a second sling stud just in front of the recoil lug for using a bi-pod.

Re: my dilema

Make sure your barrel is clean. My 7mmRM started throwing rounds all over the place until these guys on here convinced me that I had a carbon build-up problem. Nylon brush w/GM top engine cleaner and Wipeout...used alternately until it was truly clean and then my rifle went back to shooting 0.5MOA...
Good luck!

Re: my dilema

I don't think you will have to worry about the heavier SST with a close shot at your velocities. If that's the bullet you want to use then develope a load that you like for it and go do some shooting.

Re: my dilema

It depends on what you like your bullet to look like

About 2 years ago I was shooting the 30 caliber 150 grain SST at a bit over 3100 fps.
A friend kicked up a buck and it ran almost straight toward me at less than 100 yards. I shot offhand and hit him just to the right of center taking out 1 rib. The bullet went diagonally through him a small piece of lead core exited the opposite side ham without hitting any bone other than the rib. I found this piece of jacket under the hide at the point of exit:



If I were 100% sure of a 200 yard or longer shot then I would probably stick with the SST but I opted to switch to the 150 Accubond instead.

The SST did go full length diagonally through the deer so I can't complain, but I prefer a bit more retained mass.

Re: my dilema

I don't particularly like the light for caliber SST's. They do have a tendency, like light ballistic tips, of coming apart at higher velocities. The heavier for caliber SSt's just have a longer shank to keep them together and to push the fast opening mushroom plenty deep.
