Thread: I have a cunning plan

or maybe not.

A mate has been asked to deal to some problem pigs raiding a local orchard. Three of us popped up after dark last night, and sure enough, the culprits were getting stuck into the apples etc. Unfortunately, after one shot from suppressed AR15, which secured a small weiner, the rest dispersed into the thick stuff double quick. There are some decent sized pigs in this mob too apparently, but due to space issues, and nearby properties, we cant get too carried away with the shooting.
Plan B is to load up some subs for my 308 and see how that goes, used in conjunction with NV.

Rifle is Rem mod 7 with 16 1/2 inch barrel, plus DPT can.
I have some Trail boss powder and, thanks to our man in Tokoroa, some nice cast 151 gn projectiles. I don't have a chrono, but can possibly borrow one if I need to.
From what I have read, the idea is to start slightly high with the powder, and test fire without suppressor to make sure rounds A; leave the barrel B; don't tumble.

What charge should I be starting with etc etc please?

Sub loads in my 308 18" barrel is 8.3 grains trail boss. 151 grain projectiles sourced from the same supplier in tokoroa.

7.7 grain into the exact same barrel but 17" long. It seems that the longer the barrel, the more powder you need to overcome the friction.( not mentioning all kind of bore dimensions going from 0.2984 up to 0.3020" in the gun industry...)

me and Tilly will sort, that's Tills in the photo, She loves the Penguin. Might need Jazz s well.

Any help gratefully received GA.

Thinking of doing that for the roar

Probably only a minor consideration, but does a stainless barrel V blued make enough difference to be, well, a difference.

No

As above the rule with trail boss is start with a full case and work down.....Ie the opposite of normal rifle reloading.

My chrony is always here if you want it but subs is easy, work down till it goes quiet in full grains, load more in .2-.5gr around the point they went quiet and preferably select the highest charge that no shots crack and accuracy is acceptable.

I can put you in touch with yukon optics if you like......I cant understand him either (actually you are pretty good on the engrish for a pom )

I cant afford thermal mate. Will stick with my wee Yukon digi NV for now. All good at close quarters.
Might take you up on the chrony though.

PS: All Engrish not same

keh

I pull trigger something becomes food , that all I care about

Not always a good idea to start at a full case. We were sub loading a 7.62x39 and discovered that if a cast projectile exceeds 1400fps without a gas check, it turns to very small molten lead droplets and turned a rifle into a 30 bore smooth bore. It took ages to clean the lead out of the rifling to the extent we almost rebarreled....That was about 11gr trail boss. It seems about 8gr is pretty good. but we also used a 180gr too. (And we gas check now as well...)

Casts are gas checked and lubed I believe .
