Jamming To Square?

[artbosco]

The best way to prevent the mess that's created when a bullet stays in the barrel, and the extracted case pours powder into all the crevices found in a chamber, and even into trigger area, is to simply fire the round. [Outdoorsman]

Ah not a regular F-Class or Fullbore type target shooter methinks!

Correct! I only shoot competitively in NBRSA and IBS Group and Score matches.

Outdoorsman and Laurie,I know everyone(almost) refuses to jump VLD bullets but, please go to Bergers website and follow Steckers Tips on getting VLD bullets to shoot in YOUR rifle.Read why he came up with this and give it a shot. After fighting with a new rifle for all of this year with less than satisfactory groups, I tried it. Shocking! Unbelieveable! Wasted year. I had 2 three shot groups at 200yds with zero vert. This was near dark. I went home and loaded a set (24) of 105s and a set of 95s and have not had a decent day since.It's all about finding the trick that works for you in your rifle. Don't say anything doesn't work until you've tried it. You can turn yourself into a cul de sac that can take a year (or more) to get out of.
I've had 20 years of short range BR with good results so I was sure.........

John, I only shoot Bart Sauter's 68 grain, flat base Ultras in my 6PPC and only Ronnie Check's 118 grain, 9 ogive, .308 bullet, built on a .925" J-4 jacket in my 30BR. Both are jammed to a square mark or to one that is twice as long as it is wide, and have been very effective. But thanks for the info.

John,

thanks for the advice, but I already know of it and intend to give the Berger recommended large VLD jumps a try next year in my .223R/90 F/TR rifle. Apart from anything else, I'm intrigued by this issue and plan to have a look at two or three cartridges to see just how this works out.

I don't need to do this for grouping in the .223 - seating the 90gn VLD a moderate amount into the lands gave very good results straight away - the barrel and throat obviously appreciate this set-up. It's solely to address the unloading a live round issue. When I shoot on those ranges where regular cease-fires are called, I use tangent ogive bullets as a matter of course, and since none of them involves really long distances, it's no hardship.

What I do like is a tangent ogive design that matches the BC of a VLD - Berger's 0.308" 185gn BT Long-Range is my ideal, the best of all worlds you could say! I think we may see rather fewer VLDs in use in the future as more efficient tangent models appear. The other thing about VLDs is that they are more likely to be fussy than conventional designs - I won't say are always fussier, as sometimes they just work straight away as is the case in my 223 and also with Berger 105s in my 6BR Light Gun. Nevertheless, there are those times when it proves hard work, and life (and barrel life too, often) are too short to be spending multiple range visits and testing sessions on trying a number of approaches in order to eventually find one that works.
