Just starting loading using IMR-4064 under 175 gr. SMK's...
*I loaded 5 shots each at half grain increments starting at 40.5 and going up to 42.5.
*I shot these round robin style as not to be partial to any one particular load and no cleaning was done of the bore during the test.
*I had zero'd my rifle with a different round so my POI was off some from my POA each time, but regardless I kept the same POA for each shot with each particular charge weight.
*I shot 5 shot strings and allowed about 10-15 minutes in between for barrel cooling.
*Shooting at 100 yards.
*Shooting off of a bipod on the front and bag on the rear.
*I'm shooting a bone stock Stevens Model 200 in 308.. Nothing special, just trying to learn so that when I do build a shooter oneday I'll know how to work up a load for it.
*I can't say for sure where shot 5 is on 41 and 41.5 grain loads, but I feel like they went thru and existing hole. (???)
Help me learn as much as possible from this test.
What do you see?
What would you do next to dial in the load?
Do I need to looking for less vertical stringing or just the best grouping of the 5 shots? (at this point)
