Without spending $600 on a Brownell Micrometer ! I mainly want to measure my fixed choke guns ...Any advice or tips? (I do know about the silver dime trick) Thanks
 
Couldn't you just go on Google or a place like Harbor Freight and buy $20 calipers.

The problem is that choke is the difference between the actual barrel diameter and the narrowest part of the choke. The muzzle diameter only provides one of those numbers, and depending upon choke style, may not even reflect the maximum point of constriction.
 

Not sure where Gary Bulley's bore gauges are priced now (they were around $130-$140) but it will be considerably less than $600.

You could also look for a second hand Skeet's Bore Gauge.
 
You could also spend some time on the pattern board shooting patterns into a 30" circle at various distances (20, 30 & 40 yards). Preferably with quality skeet/trap or sporting clays loads (using same load and shot size). That should give a good real world indication.

Hi Roklok
I read your post on Caprivi. Congratulations.
I plan to hunt there for buff in 2026 oct.
How was the land, very dry ? But à lot of buffs ?
Thank you / merci

Chopped up the whole thing as I kept hitting the 240 character limit...
Found out the trigger word in the end... It was muzzle or velocity. dropped them and it posted.:)

2,822fps, ES 8.2
This compares favorably to 7 Rem Mag. with less powder & recoil.

I know that this thread is more than a year old but as a new member I thought I would pass along my .280AI loading.
I am shooting F Open long range rather than hunting but here is what is working for me and I have managed a 198.14 at 800 meters.
That is for 20 shots. The 14 are X's which is a 5" circle.
