If You Own One…It’s Just A Matter Of Time
The caption says it all. No worries, laugh all you want because I was. This chronograph lasted 5 hits and has paid itself off with lots of load data collected. Maybe it’s intentional for a upgrade? Lol
Finally seeing Groups For The TC Compass
Unlike my previous TC Compass in 308 (which I sent in for repair and returned replaced), my load work ups are showing good results. Keeping the groups to 3 shots due to barrel temp on this pencil barrel, I was able to produce nearly a half MOA group with a 180gr Nosler BT bullet.
This is a heavy bullet for this 1-12 twist. Goes to show there’s a little more truth about bullet stability than what is commonly thought of. More on this in a future article. Now for this bullet (Nosler 180gr Ballistic Tip) I found for my 308 this bullet likes lots of jump. After doing much research, many 30-ot-six shooters where reporting accurate loads with around a .100″ to .130″ jump. Also, Nosler posted load data for this bullet with H4895 being the most accurate and COAL being 2.800″. Nosler Load Data Here I loaded to .110″ off lands which coincides close to Nosler’s 2.800″ COAL.
So, on a good note, I found another potentially accurate load for my son’s rifle. This time we’re going to nail that IPSC consistently with this budget setup.
