Pressure point on barrel

[Bottom Fodder]

I remember that some “ factory “ rifles had a had a raised pressure point on the end of the forearm against the barrel and best I remember adjusting the forearm screw adjusted the pressure. Anybody remember this? I guess in a sense you could tune the barrel doing that

So did the 40Xs Remington

Ruger 77s had it back in the day but adjusting the screw was not part of the deal. There was an after market kit that had a plastic piece that pushed up on the stock. Required drilling the stock as I recall.

Anyone using barrels with a pressure point and placing high in competition? Serious question. I think I know the answer but perhaps not.

Yep, I think I do too. When using a pressure point as the barrel heats up and things begin to move the tune will not remain stable.

Really I guess most competition guns have a full floating barrel you know where the action is bedded and makes contact with the stock

Many moons ago, had a factory Remington Model Seven in .17 Fireball with wood stock that had a pressure point. Some genius decided it was interfering with group size and removed it. Results were the opposite.

I won’t remove a pressure point unless I‘m having it pillar bedded.

Sometimes it works, sometimes not. I had a Ruger 10-22 that wouldn’t shoot for squat. I took one of wife’s credit cards and cut shims to add pressure at the tip of the fore end.
The rifle doesn’t shoot any better but I can now afford a better rifle.

Best post in the thread!

The pressure point is a light barrel hunting rifle thing. On some it helped , some it did not. Was there to tune barrel harmonics of the light barrel.

I always looked at them as a sorta CS way for the factory to maintain a, barrel to forend gap whilst on the dealer's rack.

Saying,quality walnut not what it was....

The pressure point was taught in stock making (by hand, from a blank) in gunsmith school, and later recommended to me by another stock making instructor from another gunsmith school . Many times, it took fine tuning, little by little, to get it right. As I said, for a hunting rifle. If ya' miss, or don't put it where it needs to be the first time, critters don't tend to stick around to be shot at repeatedly. At most, 2 shots is all you're gonna' get! When it comes to the pressure point, one size does not fit all. Those used on factory built usually need tuned.

I read an article many years ago about shooters using leather shims and would move the pressure point with the shims to tune the barrel. It's been 30 or 40 years ago but I think the article was about palma shooters in Great Britain.

so, in a sense today’s tuner my have started from this?

 

[Dan V.]

That's what I was thinking.

Kind of off subject but seems like more often than not when I get a pre64 model 70 in the shop I always find interesting things under the forearm slivers of phone book, newspaper, pieces of business cards its some back in the day tuning

That would likely be NRA Service B: the slow fire bullseye matches with .303 Lee Enfields. Only service pattern barrels were permitted*, but limited bedding was allowed. Bedding meant ahimming with Cork sheet, paper, wood veneer etc. When 7.62mm Target Rifle superceded SRb a heavier barrel was allowed, usually free-floated as the NRA finally looked at what the rest of the world was doing. Even action bedding, unheard of in .303 days, was on the table.

*From memory the Australian and New Zealand NRAs allowed a slightly heavier .303 barrel based on the 1890s MLM/MLE barrel. Visiting teams could use these at Bisley, but were expected to change to a British pattern if they stayed.
