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
