David TapsonI'm wondering if we have any observations on the Bergara Hunter Extreme .308?Cerakoted SS, 18", 1:10" twist. Pic below, mine is previous version which does not have fluting. It's pretty lively to shoot, not just my observation, but then I've been doing the cross-handed thing which I will stop doing. It's ridiculous - it leaps about like a spooky horse, just about jumps off the front bag. Included are pics of muzzle - looks pretty rough to me - is this the case? This is after maybe 300 rds, cleaned with G96 only up until now, when I cleaned with Gunslick Ultra-Klenz which took off couple of copper streaks on the rifling. Either G96 is pretty good at removing copper, or this rifle is a low copper fouling rifle, not sure which. I will polish up the throat as per videos, but am wondering if I need to go full beast mode on cleaning up the bore as per accurizing book? Shoots pretty much MOA with Fiocchi Perfecta, which I hear via the grapevine is not great in these rifles. I used some Belmont SP one time the range was open at 200m and got less than MOA, but that was a three shot group, so luck might have played a part. Haven't had time/no rain to get some range time holding it properly with better ammo. |

Nathan FosterRe: Bergara Hunter Extreme .308Hi David, the Bergara is a good rifle and although there have been some hiccups along the way, this company continues to improve their products. Having said this, it is unwise to flute light weight barrels. You did well to obtain the pre-fluted model.The muzzle looks fine. It does seem to be producing very low copper fouling. It is on the other hand collecting quite a bit of carbon and will need good periodic cleaning to remove this. Besides keeping the bore protected against corrosion, one needs to let the rifle (accuracy) dictate how far one should go with either copper or carbon removal. If the rifle is suppressed or braked, carbon removal is important in order to avoid high pressures at the chamber. The subject of carbon and carbon removal was discussed in the book series. The following is a short chat which may help you and other readers. Please watch this before doing anything with the throat. https://vimeo.com/496483888 |

Scott StruifRe: Bergara Hunter Extreme .308Ive been using Bore Tech Eliminator. It attacks both copper and carbon, and also protects from corrosion for a couple weeks. It doesnt stink, and turns copper blue, so you have some idea of the amount of copper remaining. I wrap a length of patch material large enough to completely swaddle a nylon brush, then wet it with Eliminator. If you use a brass brush, it will give you a false reading, because it will turn the patch blue by dissolving the copper in the brush. I dont have any heavy copper foulers, so it saves a little time by eliminating the need for 2 different solvents. |
