Re: Walther kkm GX1?
Yana: I purchased what I think was a GX1 in the early 90's, selling it remains one of my biggest regrets in all the years I have been shooting. It was an amazing rifle. Mine had a feature I have not seen on other GX1's for sale in the past (I hope I can explain it). It had a split fore end - basical...

Re: Nerves, pulse etc in prone
Hi Roger: I think everyone deals with this issue at some point, I know I have (and still do!). I asked Nancy Thompkins about this some time ago, and she mentioned something that has helped me ever since - she simply said I should take one shot at a time, and focus / concentrate on nothing else. Focu...

Re: Buy a tuner or not?
Hi Bryan: So jealous that you have access to the Bisley range! I was there in 2009 and was in awe - what a beautiful and functional range. We will be there next year for the Roberts Team and your Nationals - I am so looking forward to it. This will be a very long winter / off-season for sure. I am n...

Re: Buy a tuner or not?
Guy: Thanks for the reply, I hope you had a great weekend! I think I may have confused my position with my previous post....i believe tuners or extension tubes that combine tuners are a huge advantage. Unless you do your own work, having some means to optimize accuracy is invaluable. You can get nak...

Re: Buy a tuner or not?
My conclusion (at this point) is that the vibrations most probably come from the fall of the firing pin and are not barrel generated by recoil about the centre of gravity - as they are in the case of centrefire rifles. So for a given rifle, it is difficult to alter the vibrations to achieve positiv...

Re: Buy a tuner or not?
Just to chip back in with my original question as Bryan has hinted at it above - if you can tune or de-tune a barrel by moving a weight forwards or backwards a couple of thousandths of an inch at a time, how will I know how much of an effect the weight and placement of my foresight is having? And w...

Re: Buy a tuner or not?
Kevin - I'm still quite new to this so forgive me for asking (and its off topic) but isn't the best crown position decided on were the barrel slugs at the tightest? cheers Bryan Bryan: I agree that RF barrels perform best with some measure of taper in them, tapering towards the muzzle. Slugging IMH...

Re: Buy a tuner or not?
Good morning Mark: I certainly appreciate your approach, and I meant no disrespect in the previous post. I have always appreciated your posts. I am afraid I fall into the "Joe Dirt" subset on the subject. Although vibration analysis is something we do in my field often, the specific model ...

Re: Buy a tuner or not?
You are implying that the length of the tuner helps to locate the node at the muzzle and not that it is effecting the bullet's path after it leaves the muzzle; correct? Mark Hi Mark: How could any tube or mass tuning device effect the bullets path "after it leaves the muzzle"???? I know t...

Re: Buy a tuner or not?
Hi Kevin, so if a barrel/action shoots well with a tube fitted, swapping to a tuner-tube of similar weight and length would give a fighting chance of seeing an improvement, allowing for operator incompetence, or at least upset things the least? Tim Hi Tim: Yes, In my experience, if the two are very...

Re: Buy a tuner or not?
Thank you for those positive comments Kevin, I seem to do most of my training by myself these days so it means a lot to get good feedback, especailly from someone of your standing. One question for you though, how do you find aperature size effecting group size? Bryan: Aperture size is unfortunatel...

Re: Buy a tuner or not?
Hi Bryan, as Kevin so rightly says (although I may slightly disagree with his percentages) the errors from hold, aim and conditions will make it very difficult to objectively rate the groups. The vertical might be down to you or might be down to the barrel/ammo. Good morning Ken! It is great to hea...

Re: Buy a tuner or not?
All: This is just my very humble opinion on the subject......... Any tuner, be it an adjustable mass device or overall length based extension tube (or combination of the two) is only a means to fine tune the system. The rifle (as a system) must be optimized or all you are accomplishing is turning bi...

Re: Anschutz 2013 question
gwsb: Not sure if I should respond, I have done some smithing (not sure if anyone would consider me a gunsmith though!). For the 2000 series action, one of the most important variables is the fit between the tennon and action ID. You obviously can't control that with a drop in barrel, and typically ...

Re: Anschutz 1913 vs Walther kk300?????
Hi Levi - here's my $.02: The Walther KK300 is a far better rifle than the round 54 series Anschutz rifles for the following reasons: 1. The Walther trigger is far better, and can be reliably adjusted to zero creep. The Anschutz geometry allows the sear to "hang" - when the first stage is ...

Re: Karl Kenyon Anschutz
I agree (regarding tearing apart Karl's work), unfortunately, barrels do wear out..........even in smallbore shooting! Using modeling clay to fill voids when bedding is a very common practice. It's the easiest (and best) way to keep epoxy from getting somewhere it shouldn't be. I have had actions Ka...

Re: Karl Kenyon Anschutz
I have had many Kenyon round action 54's in my shop, and to date have never witnessed one he silver soldered in place (certainly doesn't mean they don't exist for sure though!). Karl was IMHO the last true, great RF gunsmith of our era. The rifles he built have earned more titles than any other - wi...

Re: starik tube/tuner
All: I thought I would add a thought or two, just my opinion here (for what it's worth): There seems to be two schools of thought regarding the "tuning" of barrel vibrations (with regard to the RF sports). Tony Purdy pioneered the idea (and analysis) behind the use of harmonic resonance, b...
