Any 7mm rem mag shooters here?

[Sonny]

So just recently picked up a used but not abused Browning BLR 81 lightweight in 7mm rem mag.

I know each and every rifle prefers a certain type and weight of ammo but damn with the price and availability of ammo these days makes that's a tall order.

So far I've only shot Federal Power shocks 150 grain ammo and I'm only getting 3 inch groups. This is not good. :(

This rifle has a 1:9.5 rate of twist but that is over my head but figuired I should add this info.

So... would a heavier bullet like a 175 gr. give me tighter groups?

Found a box of Federal 175gr ammo here in town and I answered my own question. Went from 3 inch groups with Federal 150gr to 3/4 inch groups with Federal 175gr ammo. I didn't think it would make that much of a difference but it does.

Still want to try some Remington and Winchester ammo but that has to wait until I drive to the big city. Will most likely go there next month to do some Christmas shopping.

That skinny barrel sure heats up quick and then the groups spread out some.

sonny, what range distance are you shooting....do you have several distances available...AND, just how steady is your position prior to firing...?

Oh I have a good solid Predator gun rest and I also have a Caldwell leadsled but was told that it's easy to crack a rifle stock with those so I don't use it much anymore.
The BLR was used and it came with an old Bushnell Scope Chief 3x9-40 scope but I replaced it with a Vortex 4x12-40 Diamondback with BDC which seems to work pretty good.

We have a darn nice range for being a small isolated town. Two 100 yard ranges and that is what I was shooting at today. We also have a 200-300-400-500 and 580 yard ranges. The 580 yard range has a pipeline behind it so that's as far as we can shoot since we can not shoot across the pipeline right of way. But we have a lot of Federal (Crown) land where you can shoot as far as you can see. lol

We also have a pistol range, indoor and outdoor archery ranges, four trap houses but one is broken right now and a clubhouse.
