so ive had a few guys asking me if i tried or what i thought about IMR4451...actually several ppl. i know lonewolf is shooting it in his new 6 creedmoor and is pretty happy with it and since ive had an 8lb jug sitting in my safe for awhile i figured id try it out and post up the results.
now im not concerned about the temp sensitivity nor am i testing for it im just looking at the accuracy side...ive tested a few powders that everyone claims to be extremely temp sensitive and have found that they are not as bad as everyone says they are.

with regards to temp sensitivity and IMR4451 here are two good reads...you be the judge about the temp-sens part....

i was testing some 107g SMKs last weekend and they shot very well so i figured id shoot them with the 4451 because i know they are accurate with H4350 so ill shoot the test exactly the same as last weekend to give me a good idea of accuracy compared to H4350....this is the target with H4350...



i have 28 rounds loaded for this test...6mm creedmoor,107g SMks seated .025 off the lands,CCI200s and charge weights will be #1-40.5g-#2-41g-#3-41.5g-#4-42g...ill post pics later of the target after i shoot the test.

on a side note...i shot a lot of IMR4350 and the first thing i noticed when i opened the 4451 was the different sized kernels...not the it matters but i just found it kinda odd...the other thing i noticed was the 4451 smells like re-loader powders...



and what good would this thread be without some ammo porn....





and just an FYI...ive got 1300 rounds through this barrel now...i know not normal of me but ive been(and still am)just slammed at work....we will have about 25 jobs from this year rolling over into next year...but anyway at 1300 rounds ive lost .038 outta the lands/throat but its still as accurate as day one...i also havent cleaned the barrel in 850(+or- a few)rounds.
