[pork chop]

thinking of trying these in my 22 br with a 1 in 10 twist.has anyone used these in this twist rate ,their site says 10 twist min but would like to hear of anybody using them first hand

They are my head of choice in my 1:8 223, I'd imagine they'd do well in a 1:10 too.

I regularly shoot 69 smk in a 1 in 9 twist. Great results with 24.5 gn Vit N140. Similar results with TR140. I'd try a 10 thou

jump initially and try adjusting to see how groups improve.

Superb bullet for a 1x9 twist....and many powders to choose from....Using 22.1g of H335 here...I will add though that this load does not correspond to the Sierra manual starting load - I can only assume this is because the barrel twist is different; being me using the 1x9 twist, when Sierra tested with a 1x14 twist, therefore resulting in faster rpm through barrel until exiting muzzle.

..Easily MOA load at 100yds and 200yds...Also OAL of bullet differs from Sierra manual; Sierra states OAL = 2.250...I loaded first batch at this OAL length and couldn't hit a bull up the a*** with a shovel! ....Then decreased OAL by 5/1000 until down to 2.235 OAL...it's all about the testing and finding out which pill & medicine your rifle shoots the sweetest...good luck
