A small miracle has occurred, I finally found a Henry H015-223 in stock! Placed an order with Buds, looks like I got the last one they had. Now to find a H015-243 and a H015-44. The 44mag is always sold out as soon as they come in. The 243 is easier to find than the 223, but not much. Got an email from Grab-a-Gun, they had 35 of the 223s and 20 or the 44s in stock at noon on Thursday, they sold out in 10 minutes.
Ordered a Weaver Classic 2.5-7x33 and the correct base with low rings. Looking forward to working up loads and having a new varmint rifle.
