Can a Remington 750 reliably cycle 110gr to 250gr handloads?

[briannmilewis]

I am not talking about managed recoil loads, just medium loads in the 45,000 CUP to 53,000 CUP pressure range:

110 gr
125 gr
150 gr
180 gr
200 gr
220 gr
250 gr

I keep reading posts all over about how they typical will not do that out of the box, how they will reliably only reliably feed a range of loads from 150gr or 180gr and up.

Obviously I am looking for one rifle that will do the job of all the 30-06 parent case family: 25-06, 270 Rem, 280 Rem, 30-06 and 338-06.

Is there a modification that can be made to make this happen?

Is this too much to ask?

Not having that Model or being familiar with it I would think that as long as the cartridge generates enough pressure it should cycle regardless of bullet weight.

Autoloading rifles require a certain amount of pressure for a certain duration. The duration is where the lighter weights get into trouble.. They sometimes are out of the barrel before enough impetus is given the mechanism to fully function the arm. Is a reliable all purpose arm is wanted I would reccomend the M700 or the M760 as they are not affected by pressure curve duration..just pressure peaks. Please understand that as one gets further from the 'normal' bullet weight for a certain round the efficiency of the arm rapidly deteriates. The 130 grain 30 caliber is not nearly the ballistic equivilent of the 270 Win's 130 grain slug,,even if it likely leaving the 30-06 at a higher velocity.

Years ago I shot some factory 125 grain bullets in my 742 in 30-06.  Worked then.  Still have the rifle.  It's 42 years old now and works just fine with moderate loads in small base sized and trimmed brass (essentially factory fodder).

The mystery of "small base sized", can you explain this, I have read a lot of reports and it seem more black arts whether or not a semi-auto needs that king of FL resizing. What happens if you use regular FL resizer? Thanks.

I suppose you could mic an unfired factory case and compare it to a FL case.  If the FL case is the same as your factory case you should be fine.  The rifle should work well with cases sized to new factory specs.

My experience has been most satisfactory with the small base sizing die and least satisfactory with dimensions much greater than this.  Same goes for pressure.  You will do best with medium loads.

If you want to make high velocity custom reloads, you might do better with a bolt rifle than a semi auto.  Recognize the purpose of the rifle and its design features.  It chief purpose is to cycle very quickly. Everything else is secondary.

Charles p:

Medium loads are exactly what I had in mind. Thanks for the sizing explanation.

Autoloading rifles and others such as some of the lever guns have little camming force to load a tight case and lock the action. Some have all kinds of problems but I never had. I've never used a small base die and have loaded for many autoloading rifles.. The 742's while problematic in many ways have never been finichy feeders for me.. The only really finicky rifle I've loaded for was a Ruger Mini 14. It almost refused to feed with heavier than normal bullets.. Fifty and fityfive grain bullets worked just fine!! NO 63 grainers. AR15's (severak) have been the easiest of all.  It seems the Browning auto rifles are the worst offenders for needing the small base dies, but I've not had any problems.. Still have one in the vault..in 243..
